While the guide can stand alone as a technical document, it was prepared primarily as a companion to existing sports lighting standards and codes such as the Australian AS2560 series of standards. The focus on lighting requirements for cricket was chosen to fill a gap not currently satisfied by these standards – in particular, television. The IESANZ described the guide as ‘an

Philips Hue lamp ‘vulnerable to hackers’ Weaknesses in the wireless system used to control the revolutionary Philips Hue internet lamp could leave users open to cyber attack, a computer security expert has warned. Researcher Nitesh Dhanjani said vulnerabilities in the Hue wireless controller’s authentication system could make it possible for malware on the computer network to control the lights – but Philips says the risk is ‘very limited’. ‘Lighting is critical to physical security,’ said Dhanjani. ‘Smart light bulb
systems are likely to be used in residential and corporate constructions... The ability of an intruder to remotely shut off lighting in locations such as hospitals and other public venues can result in serious consequences.’ Philips told Lux Review Australia that the company uses industry standard encryption, and that the type of attack described by Dhanjani would only be possible if a computer was already compromised – in which case all their devices would be at risk, not just Hue.

Huge LED retrofit across New South Wales More than 40 Australian councils are set to upgrade their streetlights to LEDs. Councils across Sydney, the Central Coast and Hunter regions of New South Wales are expecting huge savings in energy and maintenance costs. This will be the first grid-wide rollout in Australia. Energy minister Chris Harcher announced the deal after eight successful streetlighting trials conducted over 18 months in Sydney and the Central Coast. Results from the trials showed that: electricity use was reduced by 43-70 per cent depending on the sources the LEDs replaced, that short-term maintenance was minimal, and that residents preferred the light output of LEDs to that of traditional lamps. The project will cover 41 councils across the Ausgrid network and Sylvania Lighting Australasia will supply equipment. Ausgrid owns and maintains 250,000 streetlights on behalf of the 41 councils, and reckons Sylvania will supply about 10,000 LED lanterns a year. ‘When a standard light on a suburban street fails and cannot be fixed, it will now be replaced by a super-efficient LED,’ said Chris Hartcher, Australian energy minister. ‘The

lifespan of LEDs is expected to be more than 20 years, meaning councils will pay a lot less for both maintenance and power.’ Each residential streetlight in the area concerned uses between 46 and 95W each – the replacement LEDs will use 29W. ‘Public lighting is an essential service for the community that helps make our roads and public areas safer for pedestrians and motorists,’ added Hartcher. ‘It’s great to see a local company at the forefront of this technology, helping to make a vital community service more efficient and cost effective.’

Zumtobel chiefs quit in row over Thorn strategy Zumtobel Group chief executive Harald Sommerer (pictured) and finance officer Mathias Dähn have quit in a row over the company’s strategy. The resignations follow months of intensive discussions in the Zumtobel Group boardroom over the future direction of the group and its companies, architectural fixture manufacturer Zumtobel, commercial and amenity luminaire maker Thorn and driver and control gear specialist Tridonic. It’s believed the two board members clashed with the supervisory board over strategy, including the possible demerger of Thorn from the group. Sommerer was appointed CEO in March 2010 to steer the group through the difficult transition from traditional technologies to LED, but like all European manufacturers, Zumtobel has been buffeted by market instability and the ongoing recession in Europe.
CEO Harald Sommerer has left the company
IN BRIEF Zumtobel in oled Jv the Zumtobel Group has bought out its partner Fraunhofer in the oled development joint venture ledon oled lighting. ledon oled will become part of the Zumtobel Group’s control gear specialist tridonic.
French led takeover
The Zumtobel Group has now appointed a replacement for Sommerer, Dr Ulrich Schumacher, who had a long career at Siemens, including the post of president and CEO of the semiconductor group. A replacement for Dähn is also being sought. In the months of May, June and July this year the group saw sales fall by 4.4 per cent to $417 million but profits increased by 41 per cent as cost-cutting measures bore fruit. LED products now account for 29 per cent of the group’s sales, but only 15 per cent at Tridonic.
Troubled Sill files for insolvency protection
Philips spinoff buys Hess
The troubled German architectural fixture manufacturer Franz Sill has become insolvent. The Berlin-based company filed for protection from its creditors under German planned insolvency laws in September. Sill has been in difficulties since the start of the year, and has been negotiating with its banks to continue trading. It now has three months to resolve the situation, which could involve new investors or an outright sale. It’s understood that Sill, despite its strength in exterior projectors, has struggled to make the transition from traditional sources to LEDs.
German outdoor lighting business Hess, which filed for insolvency earlier this year, has been acquired by Philips spinoff Nordeon. The deal includes Hess’s production site at VillingenSchewnningen, Germany, as well as Hess’s Scandinavian and US businesses. Around 180 staff are being kept on, the companies said. Hess went bust in February amid accusations that bosses had been overstating revenue and profits. Nordeon, which is owned by a Dutch investment group, was created last year as a spinoff from Philips, and owns two former Philips production sites in France and Germany.
Production will continue at Sill’s Berlin plant while the finances are resolved
The firm was founded in 1954 as Fuchs & Sill by Werner Fuchs and Franz Sill. The latter took over the company but died in 1990.

Dehen: Focus on profitable growth
In a bid to scale back on traditional streetlighting technology in favour of LEDs, Osram is closing down some of its maintenance sites in the United States and Canada. The restructuring of Osram Sylvania will result in 900 job losses. Osram boss Wolfgang Dehen said: ‘Our focus is on profitable growth and therefore we are consequently implementing the company’s transformation agenda.’ Osram, which was demerged from parent Siemens in July, is making lots of changes following pressure to invest in LED technology. The company previously said it plans to cut around 8,000 jobs by the end of 2014, saving $1.35 billion in costs between 2013 and 2015.

Philips Lighting’s aggressive cost-cutting plan will put the company on track to return to double-digit profit, chief executive Eric Rondolat has told investors. In what he described as a ‘crazily transforming market’, Rondolat said the rationalisation programme – under which the company has closed factories, cut staff numbers and reduced its product portfolio – would return the company to about 10 per cent profit in three years’ time. ‘Cost savings are no longer a taboo for us,’ he told his London audience. ‘We need to adapt our costs to the reality of the industry.’ More manufacturing is set to move to Mexico and China from the US and Europe, and more products will be built around a common technical platform. The company recently announced it was cutting 133 jobs at its factory in Hamilton, Scotland, as Philips phases out some luminaire products and moves production of others abroad. Manufacturing of SOX lamps will continue at Hamilton – one of the few places in Europe where equipment using the technology is still made. Rondolat predicted that both the LED components division, Lumileds, and the consumer luminaires business would be profitable this year. The latter is a key priority for the company, says Rondolat. In North America, Philips has lost market share in recent years as it struggled to integrate its plethora of acquired luminaire

brands. ‘We are now tackling this,’ said Rondolat. Automotive lighting is a growth area – the firm recently won its largest ever order from a car maker – as is controls, and the company was receiving an increasing amount in licence fees from more than 300 luminaire manufacturers that use the company’s patents. Rondolat described this as a ‘very interesting revenue stream’. He said that Philips was still the clear number one in lighting and that it was spending a third more on research and development than its nearest competitor, Osram. ‘We want to lead the technological revolution,’ he declared, citing technical successes such as Philips’ internet-connected colour-changing lamp, Hue, its creation of a prototype 200 lm/W LED tube – ‘no-one else in the world can do this’ – and the brightest OLED panels, at 6,000 candelas per square metre. ● Turn to page 62 to see Eric Rondolat’s wish list for the Philips Lighting business

PROJECT NATIONAL THEATRE OF BAHRAIN, MANAMA
Theatre of beams The National Theatre of Bahrain in Manama blends lighting and architecture to create a beautiful building. The structure is woven perforated sheets of aluminium attached to aluminium beams and supported on slender steel columns. Fakhruddin Golwala, Havells-Sylvania’s regional sales manager, says: ‘The fitting needed to fit inside the aluminium beam and to offer 180-degree illumination. There were environmental conditions to consider: it had to withstand high ambient temperatures and, on a site close to the sea, to have high ingress protection. The positioning of the fittings meant they also needed to be virtually maintenance-free.’ Sylvania supplied 1,920 Slyfog R-POP 2 models with 28 and 35W T5 options and electronic ballasts. Standard beam angle is 180 degrees with 84 per cent LOR. A 360-degree light output is available on request and was used for this project.

PROJECT PONTE 16 CASINO, MACAU
Harbour lights Macau’s only casino resort, Ponte 16, sits in the city’s Inner Harbour, a Unesco World Heritage Site. It has an ‘East meets West’ architectural style, with European and Chinese cultural influences. The resort consists of a five-star hotel, a casino, a shopping complex and Asia’s first Michael Jackson Gallery. Sustainability is a part of the resort’s corporate philosophy, so efficiency was an important aspect of its refurbishment. Retrofit lamps from Megaman’s LED series were installed throughout, with LED candles in the chandeliers of the VIP hall, and LED Classic and LED PAR38 lamps illuminating the resort’s exterior. On the first floor casino Megaman’s CFL GU9s were used in the interior chandeliers and crystal light fittings. Controls were introduced to set time schedules for the lighting, ensuring lull periods are not overlit. Over 1.4 million kilowatt-hours have been saved, preventing the emission of over 1,000 tonnes of CO2.

PROJECT PIAZZA SAN POSSIDONIO, MODENA, ITALY
Historic town embraces LED San Possidonio lies 50km northwest of Bologna in the province of Modena, Italy. The historic centre and main square of this Italian town have recently undergone a facelift. The redevelopment of the area involved, among other upgrades, a new public lighting system. An LED product with a modern design from Martini was chosen for the upgrade to ensure uniform illumination across the entire road surface. Energy savings were a starting point for the municipality, which wanted to lower its energy spend. Martini’s Stilis emits a warm 3000K light and has cut energy consumption for lighting by 53 per cent. Each unit has reduced CO2 emissions by 272kg a year. About 30 units were installed atop curved poles, with a total power consumption of 1,300W. Francesco Fregni of Martini says the overall energy consumption of a scheme lit by conventional light sources – metal halide or sodium vapour lamps, for example – would be approximately 5,000W.

PROJECT PLYMOUTH, MASSACHUSETTS, US
Plymouth win Lights at schools in Plymouth, Massachusetts in the US have been hooked up to a control system. Thanks to Acuity Brandsâ€™ Roam technology, the district has significantly reduced maintenance time and energy costs associated with outdoor lighting across all school sites. Wireless control lets maintenance staff set the lights to behave according to the demands of individual campuses. Staff can track the system so potential issues are highlighted before or as they occur, and monitoring from a single place saves time and money. The district was particularly concerned about energy costs for parking lot lighting that operated nearly 24 hours a day during winter. The lighting has been programmed to turn off after custodial staff leave at night until the early morning, when it is still dark and teachers begin to arrive. Lighting controls also help extend the life of the system.

Lighting had a huge part to play in helping hit those LEED requirements, making this VW site the company’s first with completely LED outdoor lighting, and the production halls and offices were all illuminated with energy-efficient lamps. All the effort paid off. The VW site received a Platinum LEED certificate, scoring 52 out of a possible 69. To get the LEED seal of approval, buildings are judged in six sections, including innovation, energy and atmosphere, and materials and resources. VW’s Chattanooga site received full marks for innovation, energy and atmosphere, and water efficiency.

‘Chattanooga is now a benchmark for all Volkswagen factories across the world.’ For Trilux, the German lighting manufacturer that worked on the job, the initial challenge was grappling with US standards and dimensions, which deviate from European and Australian standards. US mains is 110V, but lighting in US industrial buildings is often on a separate circuit, in this case one with a voltage of 277V. Also, US products are often made to slightly different sizes than European
‘Volkswagen Worldwide is committed to sustainable mobility and environmentally compatible production processes,’ says Hubert Waltl, member of the VW board for production and logistics. ‘We’re very proud that our Chattanooga site has achieved the LEED Platinum certification, and it confirms that we’re on the right way.

Finally, US installers are often unfamiliar with mounting rails for installing modern luminaires. ‘American electricians route cables in galvanised steel tubes that are continuously fixed to the ceilings, but then only allow room for the connection of single luminaires,’ says chartered engineer Matthias Strutz on his initial experiences on-site.
Power consumption cut After Strutz declared the trunking system mandatory for the new American Volkswagen factory, installers began their work. Up until the inauguration of the factory, US engineers installed 34km of the Trilux E-Line luminaire system in the factory halls at Chattanooga. There were also several thousand

hifeng Bridge spans the Hai River in the central business district of Tianjin. It is – you may be surprised to learn – the only inclined-pylon double-plane harp cable-stayed bridge in China. With a unique shape and complex twists and turns, it’s the city’s principal landmark. Despite its cutting-edge design, the structure had several lighting problems. These included difficulties in maintaining and replacing lamps, light pollution and waste, low uniformity and disability glare. Visually, the bridge was confused. Its traditionally-styled lighting

columns were fitted with luminaires carrying 250400W lamps. After extensive field research to explore and demonstrate a series of alternative lighting systems, Thorn’s Orus luminaire was chosen for the bridge refurbishment project. Orus has a bi-directional optic that projects light transversely to the road. It has a 35W HIT-CE lamp and its output is uniform. There is little or no glare and energy consumption is low. Mounting height is 0.9m to ensure no direct light enters vehicles, and access and maintenance is significantly easier than it was with the previous installation.

aiming ensures light is not emitted upwards and no energy is wasted on lighting the wrong areas. This sharp cut-off helps limit light pollution. According to Michael Han, lighting designer at Thorn: ‘As well as providing an ideal mounting height, the optical system offers a very sharp and controlled light distribution while optimising the efficiency of the lamp. The use of 35W ceramic metal halide lamps was the best choice in terms of light control, driver comfort and power consumption.’

recently opened Hazelmere super-site in Perth uses 60 per cent less energy thanks to a metal-halide dimming system. The Israeli-made Metrolight Ecopod high bay fitting has a 400W pulse-start metal halide lamp and dimmable electronic ballast. It follows a comparison with standard metal halide. A full Ecopod fit-out of the warehouse would need only 147 fittings, fewer than the 231 generic fittings that would be needed to achieve the same result. This in turn would mean lower consumption per unit of floor area (5.92W/m2 for the generic lamp compared with 2.29W/m2 for the Ecopod).
Gowings Department Store and adjacent State Theatre buildings in Sydney have been given a makeover and reopened as QT Sydney, a 200-room hotel. Lighting company Point of View (POV) created the lighting which had to create drama and an experience that would appeal to educated travellers. In the public spaces, the goal was to complement the design aesthetic. ‘We avoided unwanted architectural lighting projecting into the space,’ says Mark Elliott, director of POV Lighting. POV used a lighting control system and retained some halogen sources, which it says provide an ambience that still cannot be matched by LEDs.
WESTFIELD, SYDNEY Retail property group Westfield has designed its corporate headquarters in Sydney to high environmental standards. The 10-floor office building was designed to target five-star Nabers and six-star Green Star ratings. Philips installed a Dynalite A Dali control system. Energy costs are lowered through daylight harvesting and standard controls such as dimming and occupancy sensors. Each luminaire in the building is individually addressable, and lights can be grouped or ungrouped into different control areas without any rewiring. The entire system is centrally monitored through the building management system, so failed lamps and ballasts are identified automatically. In total, 300 Dali fixtures CORPORATE were installed throughout HEADQUARTERS the 32,000m2 space. A combination of fluorescent and LED sources were used, with 64 channels of switching controlled through the Dynalite DMRC210 relay fixture couplers. The remaining 236 channels of dimming are controlled through Philips’ Dynalite DDBC300-Dali ballast controllers.

MAN TONG KITCHEN, MELBOURNE The newly opened Man Tong Kitchen in Melbourne’s Crown Casino complex is designed in traditional Chinese style with a rich combination of materials and colour. Point of View Lighting Design of Sydney created a scheme which gave warmth and airiness in the various spaces, without losing sight of energy efficiency. All ambient lighting is provided by LED linear sources, concealed within architectural and joinery details. The same family of linear lighting was used in all concealed details to keep the colour temperature consistent throughout the space.

52 MARTIN PLACE, SYDNEY When a major tenant decided
to vacate 52 Martin Place in Sydney and a new office tower was planned for the neighbouring site, the owners realised they had to rebrand the building. Nineteen floors have been completely refurbished and the two ‘ground floor’ levels have been redesigned. The lighting scheme from POV highlights sculptures in the lobby with built-in spotlights, and T5 cove lighting frames the suspended artworks.
BARR SMITH LIBRARY, UNIVERSITY OF ADELAIDE Limited
daylight meant round-the-clock operation for light fixtures at the university, so PSG replaced 300 2 x 36W fluorescent troffers with 40W NovaBlade LED panels. The lighting upgrade has halved energy use, saving $15,700 a year – or $180,200 over the LEDs’ lives. Maintenance savings are $11,000 a year. The load across the ceiling grid is 3W/m2. Lux levels are about 320 lx, in line with Australian standards.
REVESBY WORKERS’ CLUB, SYDNEY The much-loved venue, which opened in 1962, has been refurbished at a cost over $9.4 million. Work started in the 3,600m2 gaming floor. Lighting design was by Point of View, which created a number of chandeliers and luminaires for the club. The gaming machines on the floor have coloured flashing lights, so the architectural lighting had to be bold but delicate. A 2.5m fibreglass dome pendant, polished black on the outside and glinting with textured rose gold on the inside, is illuminated by daylight streaming through an opening above. At night, a concealed LED strip lights it up. POV designed chandeliers in three sizes to repeat across variable ceiling heights. Inside are a concealed source of indirect light – angled to the ceiling – exposed LEDs and direct downlights.
BARROW ISLAND Barrow Island, off the coast of Western Australia, is home to a large colony of leatherback turtles as well as the site for a new liquid natural gas (LNG) plant. It was important that the plant didn’t affect their breeding habits. Newly hatched turtles follow the moon to find the sea, but if they head instead towards the lights of the LNG plant they’ll get lost and die. Lighting supplier Hadar Lighting, on discovering that turtles cannot see yellow, ensured that all floodlights within 500m of the beaches are yellow.
PASPALEY, CROWN CASINO, MELBOURNE Paspaley has been in business since the 1930s. Its boutique in Melbourne’s Crown Casino has just been refurbished, and Paspaley worked with architect Carbondale and lighting designer Mindseye to capture the brand’s image. Each display has its own lighting treatment to make sure that controlled illumination highlights each pearl. Mindseye’s approach to the façade was inspired by Paspaley’s strand-stringing technique. Forty-nine strands of LEDs are fitted behind frosted glass framed with mirrors.

NOBLE PARK AQUATIC CENTRE, MELBOURNE More than 300 Anolis ArcDot LED pixels have been installed in the façade of the landmark water slide at Noble Park Aquatic Centre in Melbourne. The lighting scheme, designed by Electrolight, transforms the 19.5m-tall structure into a beacon visible from the town centre. The ArcDot is a super-bright Cree MC-E RGBW multichip-based LED pixel fixture with an IP67 rating for good weather resistance.
NUMBER ONE BLIGH STREET, SYDNEY The Building Council
of Australia has awarded a 6 Green Star Office Design v2 certificate to Number One Bligh Street, a 28-storey office tower in Sydney’s financial hub. The office space is behind a doubleskin façade that surrounds a 135m-high naturally ventilated glass atrium. Lighting throughout the 350 perimeter offices is controlled by CP’s MWS5 microwave detectors. MWS5 makes absence detection and daylight harvesting possible, dimming to keep lux levels constant when there is sufficient daylight.

FLAGSHIP STORE WESLEY LINENS, DARRA, QUEENSLAND This factory needed a lighting upgrade, and a retrofit product had to be found that would save energy. After trials of LED, metal halide and induction units, bosses chose to install 29 200W high-bay induction lamps from Robus. ‘A lighting plan was developed and payback calculations provided,’ says Wesley Linens manager Peter Matthews. ‘Installation was straighforward with each lamp pre-wired for local supply voltage. The advantage of this lamp over other technology is that there is an extensive operating life with little drop-off in light intensity over that life. Labour savings are also expected as a result of minimal maintenance activity.’ The installation saves the company over $6,500 and prevents the emission of 16 tonnes of CO2 a year. ● What I believe: Peter Matthews, Wesley Linens, page 56
HARRIS SCARFE FLAGSHIP STORE, ADELAIDE The brief for this outlet in Rundle Place, Adelaide, was to illuminate the iconic store as efficiently as possible, while lighting the stock to attract customers. Aglo Systems worked as the lighting designers and suppliers in conjunction with the store designers, Red Design Group. The store covers 9,000m2 and consumption had to be kept to 22W/m2. Harris Scarfe chose to go with the LED option and has created one of the largest retail stores in the world to be illuminated primarily with LED.
JONES THE GROCER, SYDNEYLighting at this food emporium at the Westfield shopping mall in Sydney brings each area alive. It was designed by Point of View, which created custom steel pendants in the shape of diamonds for the retail area. In the café, suspended rectangular frames of black powder-coated bars are hung with spotlights to throw accent light onto the silvertopped tables. The main feature in the dining area is a sandstone wall, which is strongly lit by day to draw customers’ focus through the restaurant from front to back.
LOOK, by LAMP. The freshest in LED projection The new spotlight family has a replaceable Fortimo LED multichip module and passive cooling for optimum thermal management (50,000 working hours). There are models with luminous flows of 1,100, 2,000 and 3,000 lm with warm or neutral white LEDs (Ra>85), available with Flood and Medium Flood optics.
With LAMP, LED quality and high technology (5-year warranty) are available to the most demanding professionals.

Japan leads the world in LED light The growing popularity of solid state, efficient light sources such as LEDs mean the Japanese can indulge their love of bright light while embracing the traditional national virtue of frugality
The Japanese believe light attracts the crowds
f you look at the Earth from space, the brightness coming from Japan at night is pretty astounding. Talking with taxi drivers in the bustling downtown areas, the lighting is so bright that they don’t even need to use their headlights. Even moving out of these central areas, most places have security lights to illuminate pedestrian areas. Amazingly, in a narrow country of limited land, there are believed to be more than 10 million of these lights installed. Similarly, in each house or apartment, we have large ceiling lights in each and every room, making our indoors areas very bright too. In such a light-filled land, I think it’s important to understand the Japanese mind when it comes to illumination. It’s easy to see why Australians think the Japanese love lights. For example, during the Christmas season there are many places where huge lighting installations are set up and large numbers of people gather from far and wide to enjoy them. It’s Taxi drivers common for individuals to decorate their houses or gardens, which can in the bustling again draw crowds. In Japan there downtown areas, is a long-held belief that lighting the lighting is something up is a sure way to bring the crowds in – this is very much so bright that the case with our firework displays they don’t even in the summer, which attract huge need to use their groups of spectators. But even if many people love headlights” lighting, there is another traditional view – and it is a growing movement – that thrift is important. Japan, a country with limited natural resources and native foodstuffs, has always considered frugality a virtue. With this principle in mind, and with plenty of technical know-how on our shores, Japan has become perhaps the fastest adopter of LED lighting. After the disastrous earthquake and tsunami that struck in March 2011, Japan and its people have faced many problems associated with our dependence on nuclear energy. This has deepened the belief in minimising waste and, alongside
increasing electricity costs, has been a key factor in the rise of LED bulbs and ceiling lights in residential houses, as well as LED replacements for fluorescent tubes in offices, and highbay lighting in factories and warehouses. LED implementation has increased outdoors and indoors. As a result, the Japanese LED lighting market leads the world. My belief is that, over the next few years, the market for domestic lighting will be saturated, and exterior lighting applications will be the lead drivers for growth in LED lighting. At the same time, however, the competition to be more efficient and to lower costs will become even more aggressive. The themes of ‘efficiency’ and ‘low cost’ are nothing new, but I believe two key trends will evolve. First, we will become better able to harness the true potential of LEDs. For example, using home or building energy management systems, we will be able to create a new generation of intelligent lighting to make ever more efficient lighting. These could give us control of streetlights so that, perhaps, they turn on only when cars are approaching in the middle of the night or they are dimmable and can be quickly turned on to full power – again, only when necessary. Second, we will change the perception of LED light. From person to person, we feel certain LED light to be ‘cold’ or ‘hard’ but, in the future, we will be able to create highly efficient LEDs that can truly mimic the light of candles, or light seen in nature such as that created by fireflies. Eventually we will develop products with characteristics similar to those of sunlight.

Light’s multidisciplinary future Solid state lighting offers not just new fixture form factors for designers, but entirely new disciplines to learn, such as graphic design
ingapore is an island city state 137km north of the equator. It is a hub for foreign architects and designers handling projects in Southeast Asia and beyond. The population is highly diverse and you would find an international team of clients and consultants on any medium to large architectural project. English is the common language and the city is safe and well organised. All of these factors attract foreign talents and capital to the small country. Singapore is full of lighting design firms, most of which are led by foreigners. But it seems there is work enough to keep them all busy. The number of new projects coming up is exciting, and it is raising awareness of the importance of quality lighting, and the benefits of using a lighting designer. I think demand for lighting designers is rising mostly because of the difficulty of dealing with LEDs. Things aren’t the same as they used to be and it has become very easy for nonThe lighting lighting experts to mess things up. Examples of bad lighting can designer’s role be found anywhere – inconsistent should be more colour, poor colour rendering, diverse in future, glare and so on. Efficiency may have improved, but visual comfort requiring a and aesthetics have certainly been multidisciplinary compromised in numerous cases. attitude and a In 2005, the Singapore government launched a programme wider perspective” called Green Mark as an initiative to drive the country’s construction industry towards more environmentally-friendly buildings, which obviously sped up the move to LEDs. Many companies have taken advantage of that trend and sold poorly made products labelled as a ‘green solution’. A sensible client would hire a lighting consultant to protect their project. Another reason demand for lighting designers is increasing is that architecture has become more complex. Buildings are so large and complicated that architects sometimes do not know how to light them properly. The lighting has become too difficult to leave to an architect or electrical engineer.
SHIGeKI FUJII director, NIPeK

Furthermore, in Singapore the government encourages good design. The Urban Redevelopment Authority (URA) demands a lighting design concept from developers for buildings planned in designated areas. This requirement forces the developers to hire a lighting consultant to prepare a lighting concept and design document for the government’s approval. The submission even includes technical factors such as colour temperature and methods of preventing glare. With increasing demand for lighting design in the region, it is easy to be lazy and keep doing the same things – repeating the same approach. However, there are exciting opportunities for lighting designers if we break out of our comfort zone. Technologies advance design. Light sources are becoming smaller and thinner, and controlling lighting is getting easier. Smaller and thinner light sources inspire us to integrate lighting into the architecture far better than we can with conventional recessed downlights and concealed cove lighting. Also, controls let us design lighting that is more interactive and responsive. As the lighting becomes more dynamic and even animated, the boundary between lighting and visual communication media could be blurred. The popularity of media façades is clear. However, architectural lighting designers often avoid the design of content for a media façade – it is considered graphic design, not lighting design. Our firm recently designed the graphical contents for the media façade of an office tower in Singapore. Before we were appointed, the façade used to display pictograms and texts as though it were a billboard. We approached it from an architectural point of view, took into consideration the surrounding context, and produced a series of abstract animated lighting that becomes a ‘skin’ of the architecture, glowing on festive evenings. The lighting designer’s role should be more diverse in future, requiring a multidisciplinary attitude and a wider perspective. The technologies inspire us all, but at the same time a lighting designer should carefully examine both the opportunities and risks, and find the right way to implement the technologies in a creative way.

Not all LEDs emit ugly light The output of modern LEDs matches the spectra of daylight or incandescent sources, so it’s about time we stopped assuming that solid state sources are capable of emitting only poor-quality light
46 | www.luxreview.com.au | 2013 Volume 1 issue 1
Emulating daylight is the goal for many designers of LED sources
ind me one person who would say, about anything: ‘That looks so much better under fluorescent light.’ Fluorescent light sources are significantly more energy efficient than incandescent sources, yet the vast potential energy savings they offered never materialised – compact fluorescent lamps (CFLs) have less than 20 per cent market penetration after decades of availability. The cause of this great failure of CFLs was an emphasis on low cost and high efficiency at the expense of everything else, especially light quality. This misplaced focus led CFL manufacturers to develop lamps with emission spectra that sacrificed colour rendering to provide the highest possible lumens (the ‘green ghoul’ effect), resulting in user experiences that were almost universally negative. So much so, that people were horrified when the first bans on incandescent The cause of lamps took place. Unfortunately, most LED the great failure companies are now doing the of CFLs was an same, promoting blue-based LEDs emphasis on low that squeeze their emissions into the green region of the spectrum, cost and high leaving fundamental gaps in violet efficiency at and cyan, and skimping on deep the expense of red whenever they can, all to get the numbers for lumens and lumens everything else” per watt as high as possible. We must not repeat the mistakes made by CFL manufacturers, or LED users will be disappointed and adoption will be limited. What we all agree is that good quality light is not some great secret – everyone knows that daylight and incandescent sources have it. What do they have in common? It is simply a full visible spectrum of light. A simple rainbow tells the story. Can you imagine a rainbow without violet, blue-green, or deep red? CFLs and blue-based LEDs cannot provide full visible spectrum light because of the efficiency and cost challenges
they present to their manufacturers, that have consequently been forced to distract consumers with an emphasis on lumens per watt and product lifetime rather than light quality and user experience. With the emergence of GaN on GaN technology, we have for the first time a true full-visible-spectrum light source. Now we can not only match incandescent lamp emissions, but also daylight, without reproducing the parts of the spectrum in the UV region (it is potentially harmful) and the IR region (it is wasteful). The great myth that energy-efficient, man-made lighting must necessarily emit light of poor colour quality is shattered. It may be hard to believe, but it’s true: we can now create the highest quality light possible, in any form factor, from a high-intensity directional source to a nondirectional luminaire. We can deliver uncompromising full-visible-spectrum light with all the dramatic energy savings of LEDs. Those that fought against the ban of incandescent lamps will look at our lamps one day and think – what on earth were we fighting for back then?
Reality check LED products have to be safe to be on sale, right? Gordon Routledge, lighting expert and publisher of Lux Review, tackles another lighting myth

INSIGHT AUSTRALIAN STREETLIGHTING STANDARDS
A new standard must take
ustralia’s streetlighting market is a hot topic. That’s because the local standard on road lighting is up for revision. More specifically, it’s Part 6 (AS1158.6), the section that covers luminaire requirements, that’s currently under review. A legislative overhaul wouldn’t normally cause a stir, but consider this: in its current form, AS1158.6 excludes the use of new technologies such as LEDs. LEDs have their advantages and disadvantages. In this case, the advantages are fast outweighing the disadvantages and LED lighting is becoming the most viable technology in many applications.
Worldwide trend There have been some big shifts towards LED streetlighting around the globe. Los Angeles, for example, is progressing quickly on its 210,000-luminaire retrofit to LED, and the UK has numerous private finance initiative projects that have been instigated to take advantage of the benefits of LEDs. And I have not read of a single major project where the consensus – from authorities or from the public – has been negative. In other fields, such as medical and scientific research, Australia pushes boundaries and is investing heavily in research and development. As I write, a team from the University of Queensland is in Norway preparing for the next launch in the advanced engineering scramjet project that is developing the future of space travel and exploration. At the same time, Australia’s lighting committee only recently convened in Sydney to discuss whether ‘new’ technologies such as LEDs are suitable for illuminating our streets. Why is Australia acting only now? The first point to consider is the way in which streetlighting is managed
52 | www.luxreview.com.au | 2013 Volume 1 Issue 1
here. Most of our 2.3 million streetlights are maintained by energy distribution businesses, which have strict guidelines on the equipment they can use. Because of this, the road lighting standard has been written to satisfy the performance requirements of streetlighting, and not to reflect best practice. Second, those guidelines do not specify minimum performance standards for the management of fundamental aspects such as safety. Instead there are strict stipulations about product forms and requirements. This makes them inflexible – they cannot make allowances for advances in technology unless the committee reconvenes to discuss the application of each and every new source. For example, there is a requirement for maximum luminaire weight, the value of which depends on whether the fixture is for pedestrian or vehicular lighting. Why does this have to be in the national standard? Surely the maximum weight of a luminaire should be a result of the structural strength of the mounting system. For new streetlighting installations, a pole, bracket and foundation can be designed to support any luminaire of reasonable weight. If a client is retrofitting a luminaire on an existing bracket-andpole arrangement, the client should specify what the maximum weight should be to ensure the luminaire will be installed safely. There need not be a generic standard for all streetlighting. There are also many references in the standard to

the benefits of certain LED luminaire form factors, such as the reasons for deploying a visor or the benefits of using the same optic for each LED chip. There are some advantages to these methods, but there are disadvantages that are not discussed. There are also alternative methods, which are not discussed at all. Mentioning one method in a positive light ensures a bias towards any products using that method, distorting what could otherwise be a fair market for all of the products that could be used effectively.

Safety first Whether it relates to a service, product or process, any standard should stipulate the minimum performance requirements to safely carry out business. Yet in the current draft of AS1158.6, minimum performance standards have been exceeded by requirements that do not necessarily contribute to achieving best practice. This can favour some products over others and does not promote fair trade. There are numerous LED streetlighting luminaire makers and distributors that want to compete in a market that is open to the best solution. This is why the standard review has caused such a stir. But the review represents an opportunity to level the playing field. Whether we drastically modify the luminaire requirements or abandon AS1158.6 altogether and default to the minimum performance requirements of AS60598, there is a chance to makeÂ significant changes to the market. This has been an Ashes summer, so let me finishÂ with a cricketing metaphor: let us allow the umpire to change his call and ensure a fair competition all round.

ENERGY VAMPIRES HIJACK HOME LIGHTS Residential lighting in Australia is in the grip of an unhealthy fascination with energy use. Renegades with no lighting knowledge are busily ‘upgrading’ lighting all over the place to low-energy LED. These energy suckers promise extraordinary energy savings in homes by simply updating globes to their whizz-bang brand new LED. With no prior experience or technical lighting background (so we must forgive them their ignorance perhaps) they present these products to unsuspecting home owners under the guise of saving the world one LED at a time, or worse still, improving residential lighting design. Lighting professionals everywhere cringe when they see another of these get-richquick schemes – oops, I mean energy-saving, light-improving business opportunities – appear on the horizon. But with such a limited understanding of lighting in the general population, how can we possibly expect home owners to know any better? It is only through openly and widely sharing our collective experience and knowledge that we can help people learn enough to avoid the next unbelievable sales pitch. The more the lighting community shares its collective knowledge, the better lighting will become. More people will understand its impact on our daily lives, and hence put greater value upon it. Who knows, perhaps a slow lighting movement (in the vein of slow food) will turn people away from

MORE ADVICE FOR AN INDEPENDENT OSRAM I found your article, My 10step plan to make Osram great (Lux Review, Volume 2, issue 4), really interesting as I have been trying to figure out the company for years. In particular, I found the suggestion that the company should change its culture as totally valid. Independent from Siemens, it now has the opportunity to build a different relationship with its customers. The further suggestion that it might acquire other companies makes sense in that it can offer an integrated solution to customers.
And it needs to work increasingly close with its distributors; in particular those who can provide a onestop shop. As for OLEDs, these were conceived more as a replacement for LCD screen and backlighting applications, not a replacement for LED. Naturally the ideal app for OLEDs is the home of apps – the mobile phone. Most of us in the industry focus on products. But we must also look at our suppliers and manufacturers and examine how strategic they are. The time is right for customers to exert some pressure on Osram. And also for Osram to learn the fine art of bi-directional communications with its customers. Good article by the way: It’s good to shine a spotlight on the business aspects of lighting. RAY BENNETT Partner, Analog 42, UK
NO BASIS FOR COMPARISON I found a recent visit to the Meyer factory interesting. The company has a mock-up area where we could do direct comparisons between LED and conventional luminaires. Most of the results were impressive. Results at lower wattages were awesome: 9W LEDs competing with 20W metal halides and packing quite a punch, although a few higher wattage floodlights did not impress much. These were nonarchitectural LED prototypes for fast-moving commercialgrade products used in general site lighting, such as construction areas. They did not have individual LED reflectors or lenses, and I guess a lot depends on the way a particular LED luminaire is engineered to suit a particular application. The architectural ones were treated with individual LED refractors and lenses, so the delivered lumen performance was right at par, if not better than, the competing metal halide sources. The optical control was better in the case of the architectural LEDs, but generally it was difficult to compare the optical systems of the different types of LED luminaire, unlike metal halides that follow the good old lamp + ballast + reflector + housing = luminaire formula. In the case of LEDs it’s more chip + LED + phosphor coating + bin + driver + drive current + individual refractors/ lenses + housing + heatsink + L70 + LM79 + Zhaga compliance + aargh… I imagine this will always be an issue until Zhaga comes into global effect and some standardisation
LIGHTING TALK takes place. But having said that, LEDs are almost there, for sure. Once some international standards come into effect, all the confusion will be phased out. FARAZ IZHAR Senior lighting designer KEO Design Abu Dhabi, UAE
THE HEAT IS ON The Lighting Talk debate on LinkedIn about what causes LEDs to explode is very interesting. I personally see little success in stuffing an LED MR16 retrofit into most of the already too-tight MR16 housings. I’ve seen overheated 20W MR16 halogen fi laments fail by melting themselves through the quartz envelope. Some of the larger bodies might work… maybe. I’ve retrofitted a few tight MR16 housings with LED MR16 lamps for an atrium in an historic gallery by adding a machined ring that thermally connects the lamp’s rim or part of its fin structure to the body of the fixture. They still experienced high driver component and LED temperatures, but far lower than non-modified products. We also experimented with fi lling the body of a fixture with thermally conductive epoxy potting material, but found the cost and mess troublesome – even though the results were pretty good. I advise people that come to me to find a suitable LED light fixture to replace the 12V heads, and toss the old product. The end result is superior and far longer lasting. KEVIN WILLMORTH Owner, Lumenique Milwaukee, US
SELLING THE BENEFITS OF LEDS I saw your post about Cree’s TV ads for their retrofit lamps on Lighting Talk on LinkedIn and just had to watch the video. A few of the videos actually. There was a lot of talk in the forum about whether or not such things are good for the industry and if this is a sign of LEDs going big in the consumer market. If normal people accept LEDs at home, then there isn’t really any stopping the rest of the world. These adverts are fun and engage non-lighting people with the benefits of this brilliant technology. The coffin was a great touch, although, as your technical editor Alan Tulla suggested, a cremation would have been more fitting. The whole industry should be screaming about LEDs. LEDs aren’t the future; they’re the present. I hope to see more promotions, more events and more adoption of LEDs. I hope everybody stops dillydallying around in fear of losing a history that we should be ready to let go off. You don’t see people refusing to buy iPads, preferring their IBM desktop machine of the 1970s. You don’t see people sticking to dial-up instead of connecting via broadband. You sure as hell don’t see anyone walking around with the bricks we used to call mobile phones. So why on earth are we still so obsessed with old lighting models? MARIANA SUMMERS Independent lighting consultant Los Angeles, US
HAVE YOUR SAY Editor@luxreview.com
WHAT’S HOT? What’s happening with Zumtobel? Harro de Cocq, Xycarb Ceramics, Netherlands LED-based lighting might be too much of a game-changer for traditional luminaire manufacturers to engage with in an evolutionary way. Certainly when there is no affiliated or internal LED (highquality) competence. On top of that, high quality (high-efficacy) conventional luminaries, until very recently, were outperforming LED luminaries (at equivalent lumen packages), while involving way lower investment. Challenges in retrofitting James Benya, Benya Burnett Consultancy, California, US I can’t believe how often I’ve handed a client a rock-solid study showing a three-year payback and having them either not believe me, or not be willing to invest. I discussed adding controls to the Denver airport, which could save $1 million per year in energy costs with a five-year payback and the city has something better to do with its money. What retailers want Douglas MacDonald, Insight Business Applications, UK They want simplicity, affordability, and lots of light that makes everything look nice – for some shops that we have retrofitted, that just involved putting in 1,200 x 600mm recessed luminaries with four 20W Cool White LED tubes per panel and a prismatic diffuser. Lighting design Inci Zeynep Kaban, ACT Lighting Design, Turkey I think it is important to include lighting designers in projects, with the team of engineers and architects, at the right phases of projects and under the correct definition of the profession and scope of work. What direction will the lighting industry take Gregory Moreland, Moreland Lighting, Los Angeles, USA With new regulations and industry standards here now and coming up you need to ask yourself “what will it cost your company when you are caught selling non-compliant light because you didn’t measure it yourself”?

What I BelIeve Peter Matthews
When we weighed everything up, induction was the choice for us over LEDs”
56 | www.luxreview.com.au | 2013 Volume 1 Issue 1
Peter Matthews Manager, Wesley Linen Services, Brisbane We needed to replace our mercury vapour and sodium lighting Our business employs around 85 staff with an annual turnover of $8.5 million, processing on average 85,000 kg of hospitalbased linen for approximately 150 customers. The problem we had with our existing lighting was that the light output from mercury vapour and sodium decays over time. We had to relamp the installation every year. When we did some measurements with a lux meter, we found that lux levels at the linen processing stations were well below Australian standards. Reliability and maintenance are critical It’s essential that our linen hire service is available on time all the time. Our mix of mercury vapour and high-pressure sodium units didn’t give me reliability over time. We couldn’t maintain them during normal production hours because of their location, which meant having to get contractors in after hours and on weekends at great expense. It was LED versus induction lamps We were aware that new technology was available including LEDs and induction lamps. We had some discussions with our local electrical wholesaler and got samples of both technologies, installing them in two key areas where we could measure the performance and also get feedback from staff. Input from staff was important because I wanted to ensure there were no issues with the colour of the light, flickering and so on. Staff were put off by ‘bright’ LED light We ended up choosing the induction lamp option, mainly because our staff told us that while the light output of the LED lamps was sufficient, they felt their eyes were ‘drawn into’ the lamps, leaving them with the impression of a burning mark on their eyes. They said it was like looking into a very bright lamp, so that for a while their eyesight was blurred. I couldn’t have staff experiencing that sort of issue. The induction lamps will last for longer The other factor was that during the costing process we found the LED option was around 25 per cent dearer, and didn’t have the longevity of the induction product. The Roben 200W induction lamps are guaranteed for 100,000 hours, which will see me out. Also, induction offered us about 1.2 years return on investment, while LED was about two years. When we weighed
everything up, including the total lifecycle cost over time, return on investment, reduction in carbon emissions and improved power factor, induction was the choice for us. Staff appreciate the whiteness and uniformity of the lighting After five months we’ve not had any issues. Staff have commented on how the light in the plant is all the same whiteness, unlike the variation in colour we had with the previous lamps. Time will be the judge in terms of whether the induction lamp was a good decision, but so far I’m impressed with the light output – it’s very consistent. Better lighting benefits an ageing workforce It’s difficult to quantify the improvement in productivity, but I’d say the consistency of the lighting through the work stations has helped people to be more thorough in their inspections. The number of complaints about quality is certainly dropping. That’s not entirely attributable to the lighting upgrade, but it’s made the staff’s task a little bit easier because they can now see properly – and with an ageing workforce, that is something we have to consider. It’s important to trial products and involve your staff My advice when upgrading lighting in warehouses and factories? Start by measuring your current light levels and whether they are suitable for your processes. Then you need to research your options – the internet is very useful. We were given the opportunity to trial lamps and that proved extremely helpful. It also gave the staff some input into the process. We’re also in the process of improving our plant’s power factor Energy efficiency is a significant cost factor, particularly in keeping us ahead of the opposition. We’re currently researching ways to improve the power factor for our plant, and I’m hoping we’ll have a solution in place within 12 months. Laundry equipment uses a lot of motors, and as a result you don’t have 100 per cent efficient use of the power. We’re achieving about 79 per cent, which means we’re effectively buying 100 units of electricity but only using 79. There is smart gear you can purchase that brings that efficiency up to around 96 per cent, so that’s where we’ll head. Generally there’s a return on investment of one to two years, so it’s a good financial opportunity. ● See page 40 for more details of the lighting refurb

Lighting in the vanguard of
EMISSIONS CUTS no gradients
Laura Fuller of the UNEP/GEF en.lighten initiative explains why efficient lighting is the key to quickly cutting global carbon dioxide emissions watermark
lectricity use for lighting represents about 15 per cent of global power consumption and 5 per cent of annual CO2 emissions worldwide. Current trends indicate that the global power demand for lighting will be 60-70 per cent higher by 2030. Action is needed urgently, especially in developing economies where electricity and consumption stackeddemand logo (for sharing only) is increasing rapidly. In 2009, to accelerate the transition to environmentally sustainable lighting, the United Nations Environment Programme (UNEP) and manufacturers Osram and Philips, with the support of the Global Environment Facility (GEF), established the en.lighten initiative. The project has convened governments and lighting experts from more than 40 international organisations to deliver guidance on the development and implementation of national and regional efficient lighting strategies. A global target of 2016 has been set for all countries to have phased out, to be in the process of phasing out, or to have policies in place to phase out, inefficient incandescent lamps.
Laura Fuller says efficient lighting could save the equivalent of twice Australiaâ€™s total CO2 emissions
Efficiency and affordability By harmonising minimum energy performance standards, product labelling and the testing methods for verifying compliance, developing countries can join larger markets, increase demand and benefit from greater access to more energy-efficient lighting products at affordable prices. UNEP estimates that replacing inefficient on-grid lighting globally would result in nearly 1,000TWh of electricity savings a year, equivalent to over $110 billion and the mitigation of over 490 million tonnes of CO2 emissions. If solar LED lanterns replaced kerosene and candles for off-grid lighting, they would displace 90 million tonnes of CO2 emissions and
Global efforts to phase out incandescent lamps should be under way by 2016
significantly improve health and safety. The CO2 savings potential for on-grid and off-grid lighting combined is 580 million tonnes, almost twice the CO2 emissions of Australia. If all light sources were switched to more advanced LED technology, global electricity consumption for lighting would be reduced by more than 52 per cent and 735 million tonnes of emissions would be avoided. Moving to efficient lighting can rapidly and significantly improve the reliability of the electricity system without having to build expensive generation facilities. With a global transition to efficient lighting, more than 250 large coal power plants with a capacity of 500MW could be eliminated. The operating cost savings would allow for the expansion of electrical services into under-serviced areas.
Wholesale transition West Africa is the latest region to make efforts to promote energy efficient lighting. A complete transition there could save 2.4TWh a year, about 6.75 per cent of total electricity consumption. If all Economic Community of West African States (ECOWAS) member states agreed to adopt more efficient lighting, the region would save an estimated $220 million a year in energy costs. ECOWAS was designated a pilot region for en.lightenâ€™s Global Efficient Lighting Partnership Programme, a voluntary initiative backed by 50 countries that supports policies and actions to phase out inefficient lighting. The global transition to energy-efficient lighting would save billions of dollars in electricity costs, boost economies and create green jobs in lighting and lighting-related industries. Improved access to electricity for millions of people would lead to increased productivity, income and quality of life. All of this makes the transition to energy-efficient lighting a win-win-win for the lighting industry, governments and users worldwide.

COUNTRY REPORT JAPAN
A new landscape takes
SHAPE COUNTRY REPORT
The lighting landscape in Japan is evolving rapidly as LED adoption is driven by some surprising names, reports Gordon Routledge
uring my last visit to Japan in January (Lux Review Volume 2, Issue 1), I struggled to find LEDs as I walked around the streets of Tokyo. I found this a little odd, because Japan is often considered a leading adopter of LED lighting. In the six months since my last visit, a lot as happened. Perhaps I spurred the Japanese lighting industry to action, or perhaps I was just looking in the wrong places. Either way I’ve found parts of Japan that are a pure LED fest. I started this visit in Japan’s second city, Osaka. Like many cities around the world, public transport networks are adopting LEDs with gusto, in particular retrofit LED tubes. Stations are often open 24/7, so the limits on maintenance make LED sources ideal – and Shin Osaka station has installed thousands of them. At first it is difficult to realise you are looking at an LED tube, because the ones in this installation have a near

360-degree light output and uniform lit appearance. A visit to the recently opened Osaka Grand Front shopping complex confirmed that LEDs are becoming the default option for new-build projects. The entire public space, and most of the shops have 100 per cent LED lighting – but again you would have to be an LED aficionado to notice.
New drivers In Tokyo, a visit to Stanley Electric’s new headquarters was a surprise: 100 per cent LEDs across the entire building – from car park to staff canteen. But it’s a well designed and executed lighting design, not the usual grid of recessed exposed tube fittings prevalent in traditional Japanese office blocks. It is rare to find 100 per cent LED projects elsewhere in the world – most projects today are a blend of LED and traditional technology, particularly in new-build projects because lighting
It’s not the traditional lighting players that are doing the innovative thinking’
is specified a number of years before the principal construction work. This newfound enthusiasm for LED technology in Japan reveals exactly who is doing the innovative thinking – and it’s not the traditional lighting players. Stanley Electric is not a traditional player in the mainstream lighting market, its background is automotive lighting. Automotive is a tough environment. Products have to survive extremes of temperature and must be designed to rigorous standards in a stringent business environment of cost control and high quality. It’s going to be interesting to see how automotive lighting players add a new dynamic to mainstream lighting with their considerable knowledge in optics design.
lighting control, making systems capable of reacting to the needs of users automatically. It smacks of Big Brother, but perhaps this is the missing piece of the controls jigsaw. Optex is the parent company of Raytec, which is starting to build these types of controls into intelligent outdoor security lighting systems.
Picking up the pace So what can we take away from all this? The market is moving fast and picking up pace in new-build and retrofit applications. New companies with considerable electronics expertise are injecting a different dynamic into the lighting market, exploiting considerable technical prowess from adjacent markets and adapting to suit the needs of mainstream lighting. However, it’s not just about technical innovation. Sales innovation is as important. Many Japanese companies have extensive local sales networks across the globe, and as Ricoh has demonstrated, you can often use a different route to market to achieve a quite spectacular result. My only worry is: what have I missed this time?
LEDs are becoming the default option for new-build projects in Osaka
Another new entrant to the lighting market is photocopier and printing giant Ricoh. The company has clocked up sales of over a million LED tubes in Japan. Apparently the person who looks after the office printer is also a good route to market for LED tubes in Japan. The simplistic nature of conventional Japanese office lighting makes the market easy pickings for retrofit tubes. (Ricoh is set to enter the European market with a product launch at the LuxLive exhibition in London, UK, in November). One piece of lighting kit you’ll struggle to find in Japan is controls, so the Japanese market represents a huge opportunity. Several electronics companies – who have recognised the potential of the retrofit market – are developing wireless controls networks. They certainly have the skills to deliver. During a visit to Optex, a global supplier of sensors to OEM security alarm businesses, I witnessed the kind of technology that can be built into a sensor. For example: sensors that cannot only detect people in a room, but how many there are, what they are doing and the direction they are walking in. This kind of sensor technology could revolutionise

Rondolat is under pressure from investors to increase profitability
wants 62 | www.luxreview.com.au | 2013 Volume 1 Issue 1
Philips may be the top player in lighting, but the market – described as ‘crazily transforming’ by CEO Eric Rondolat – is giving the Dutch giant headaches. Ray Molony imagines the top 10 gifts Eric would want for his birthday
A 10 PER CENT PROFIT MARGIN
Rondolat has promised investors he’ll take Philips’ profits to between 9 and 11 per cent in three years’ time. It’s a big ask in the current market and won’t be achieved without some pain. It means he’ll have to keep cutting costs and maintain margins from both traditional technologies and LEDs, despite falling prices in both sectors.
A BIG TURNAROUND IN THE US
Philips’ operations in the US are a bit of a mess. It bought a lot of luminaire firms during its spending spree – not least Genlyte, which it bought at the top of the market for $2.41 billion. Integrating it has become a headache for US boss Bruno Biasiotta. Philips has lost market share, and it must reverse this trend.
LUMILEDS IN PROFIT
It’s no surprise that Philips’ LED components division Lumileds has been losing money. Although it has lots of patents and a strong position in the OEM, car lighting, camera flash and computer display markets, there’s been massive oversupply in the sector, especially after the Chinese government encouraged its manufacturers to get into LEDs. Eric’s hoping to get it into the black this year.
CONSUMER LUMINAIRES IN PROFIT
Despite a strong brand and great kit, Philips has never made money in the residential luminaire channel. It would love to be the Apple of consumer lighting, and its Hue internetconnected lamp has attracted lots of media coverage since its debut last year. Now, with licensing deals from the likes of Disney, Eric hopes to reverse this.
A SHINY GOLDEN TAIL
The ‘golden tail’ is what lamp makers call the traditional stuff such as halogen, fluorescent and CFL. It’s still where they make most of their profits. The challenge is to extract as much money as possible here while growing the LED side.
A BIGGER SLICE OF THE CAR MARKET
Osram is the number one manufacturer in the automotive lighting market, and Philips is tired of being in the passenger seat. It has signed a few significant deals with carmakers, and is hoping that OLEDs will create more opportunities. The company recently supplied a three-dimensional OLED panel for a concept version of the Audi TT sports car.
Philips has lots of factories in expensive places like Europe and the US. It wants to close most of them and move production to both Mexico and China. The Philips language for this is ‘rationalising its industrial footprint’. It’s a key part of the company’s cost-cutting programme and will help Eric achieve his profit target.
There was a time when lamp companies never killed off products. They just stayed in the catalogue, which got bigger and bigger. No longer: Philips can make more money if it has fewer products built on a ‘common platform’. And it’s not just lamps; as US chief Bruno Biasiotta puts it: ‘Why do we need 16 different types of floodlights?’
AN OLED BREAKTHROUGH
Despite the hype from Osram and Philips, many remain sceptical about organic LEDs. Why use OLEDs when LEDs are perfectly adequate – and vastly cheaper? True, Philips has the brightest OLED panels at 6,000 candelas per square metre, and it’s claiming the best lumens-per-dollar package, but a profitable business still looks a long way off.
GOOD CUSTOMER SOFTWARE
A company with customers, employees and facilities all over the world must have a really good computer system to keep track of it all and enable the sharing of expertise and ideas. So Eric is subscribing to Salesforce.com, the all-singing all-dancing customer relationship management system. Lux Review Australia can recommend it – we use it for all our data.

Why every manufacturer wants to be
THE applE of lIGHTING James Holloway discovers how the lighting business is learning from companies like Apple, and creating products that are smart, sexy and ready for the digital world
f all the changes in the world of lighting, none can have been more unexpected than this: lighting is becoming sexy. Beautifully designed luminaires are nothing new, of course, but with the growth of LED lighting, even the humble lamp – once a commodity product – is rapidly gaining cachet, with products such as Philips’ Hue wireless light bulb entering the public consciousness as desirable items of consumer electronics. Are we seeing the Appleisation of lighting? ‘I think that’s a great description for some of the innovative products of today,’ says Dr Wendy Davis. Davis, who researches the interplay of light and user experience at the University of Sydney, argues that the controllability and ‘hipness’ of LEDs have been an inspiration to designers of lighting products. But has Apple been a direct influence? ‘Absolutely. Apple has influenced industrial design across many product sectors,’ says Davis. ‘My earliest encounter with a lighting product in this vein was Philips’ LivingColors, a remote-controlled colourchange light fitting for the home launched in 2007. I saw it during a visit to Europe and was struck by the design of the unit and remote control: it was sexy.’ But Davis thinks the lighting industry is still catching up with consumer electronics as far as product appeal is concerned, and that’s letting electronics firms move in on traditional lighting companies’ turf. ‘Lumileds was originally formed as the optoelectronics division of Hewlett-Packard,’ Davis points out. ‘Osram Opto Semiconductors traces its roots to the semiconductor operations of Siemens. Verbatim, a company many people recognise from the days of floppy disks, is in the LED and OLED business now. So is Samsung.’
64 | www.luxreview.com.au | 2013 Volume 1 Issue 1
If Apple has been an influence, it is in no small part down to Jony Ive, the industrial designer whose iconic designs of the iMac computer, followed by the iPod, iPhone and iPad, helped resurrect the company under single-minded CEO Steve Jobs. The iPod, iPhone and iPad have eclipsed Apple’s computer sales and become almost synonymous with the MP3 player, smartphone and tablet computer. They’re beautiful products, and if that beauty comes at the expense of repairability or upgradability, customers don’t seem to care.
Timeless design principles Philips’ Hue is helping turn light bulbs into must-have consumer products
But Apple didn’t invent pretty products, and it would be unfair to suggest that aesthetics only became a concern in the post-iPod world. Andreas Henrich, managing director of Anglo-German luminaire maker Wila is cautious of describing product design as
Plenty of LED products on the market today have luminous efficacies that are lower than fluorescent alternatives, but people are eager to use LED” The influence of Apple’s elegant design can be seen more and more in the world of lighting
Wendy Davis, University of Sydney
‘sexy’, as if it’s all about fashion. To him, it’s about timeless design principles. ‘We have a clear directive to follow three principles: build minimalistic, be modular and be visually clean,’ Henrich told Lux Review Australia. The last is a priority where Wila fittings are seen ‘in the architectural context’. Henrich says this means putting light first, with small fittings, narrow trims and flush finishes. ‘This might lead to an individual design language and maybe some people will find this “sexy”,’ he says.
Inside and out
Wila’s Alphabet downlight features a distinctive heatsink design
light bulbs (something compact fluorescents never managed in the consumer market) it’s their electronic nature that may yet ensure their commercial longevity. ‘LEDification is more than adding another lamp,’ Henrich adds. ‘It is the integration of illumination into the world of electronics.’ Davis agrees. ‘I remember listening to a group of men raving about LED torches’, she says. ‘I had never seen people outside the industry genuinely excited about a lighting technology before. Desire for energy efficiency is part of it, but it doesn’t tell the whole story. Plenty of LED products on the market today have luminous efficacies that are lower than fluorescent alternatives. But, people are eager to use LEDs.’ She adds, however, that it’s the combination of aesthetics and digital controllability that appeals to designers and manufacturers.
Complete control It’s arguably control that is most exciting to tech-savvy consumers, and no product has capitalised upon this more than Philips’ Hue, a colour-changing LED lamp that can be controlled and programmed using a smartphone. Hue is available exclusively from – where else? – Apple Stores.
When designing for the commercial market, Wila has to worry about light output ratios and glare indices, but Henrich asserts that the aesthetics of lighting products will become more important still. One need only look at the beautifully crafted heatsink of Wila’s Alphabet downlight (pictured below) to see that aesthetics are a priority for the company – especially when you consider that the heatsink is concealed once the product is installed. Even the bits you can’t see look great. Is the lighting industry right to pay such heed to consumer electronics? ‘Absolutely, and for many reasons,’ says Henrich, before pointing out that Wila started out in 1857 as a brass forming manufacturer making pretty bedknobs. Just as Wila was able to transpose that expertise into making light fittings, so electronics companies today need make only a relatively small sidestep to become lighting manufacturers. It would be an oversimplification to attribute Apple’s success solely to aesthetic appeal, and similarly the loftier profile of lighting products is about more than the appearance of lamps and luminaires. ‘Apple’s success was and is not only the physical appearance of the “design factor”,’ Henrich adds. ‘It’s the way we can use the product in a natural and self-explanatory, intuitive way.’ Though LEDs are fast gaining public acceptance as a hip, energy-efficient alternative to incandescent

Hue lamps, and includes the LivingColors wallwasher, linear LED light strips and Philips Ambilight televisions. Now, not only can Ambilight TVs backlight a wall with light that matches the on-screen action, it can make the ambient room lighting do the same.
‘We can scare the ghosts away,’ says Filip Jan Depauw, senior global director of connected lighting at Philips (or ‘Godfather of Hue’, as he’s more commonly described). He explains how remote control, automation and programming can be used by parents to alleviate, say, a child’s fear of darkness. But that’s only the beginning. The latest update to the Hue app adds support for the web service IFTTT (short for ‘if this then that’), which bridges numerous internet-enabled services and data sources so that events in one can trigger actions in any other. In the case of Hue, this means you could set the colour of your bedroom lighting to reflect the weather outside. Or, as Depauw suggests, your home office lighting could briefly flash green or red when your stocks and shares rise and fall. ‘Suddenly there is no right or wrong in what you do with light, but we as Philips provide you the tools [so] you as a consumer can do whatever you think is right,’ says Depauw. And by releasing application programming interfaces and software development kits, Philips is inviting developers and users to customise their lighting to the nth degree. Depauw enthusiastically cites the example of Australian father Jim Rutherford who, with his son, developed an app to link Hue to the hugely popular computer game Minecraft, in which the action revolves around in-game day and night cycles. Rutherford’s app adapted the lighting in the room to match that in the game, creating a more immersive experience and giving players useful visual cues. The Hue range now includes a family of colourchanging products that can be synchronised with

Making connections Ultimately, it may be the simplified connectivity and control made possible by LED technology that is the most meaningful manifestation of an ‘Appleisation’ of lighting. And though some of the examples are gimmicky, Depauw believes Hue can make a meaningful difference to users’ well-being. However, all agree there is much further to go. ‘While lighting could now be integrated in many products that we use daily (TV backlights, furniture and even clothing) it becomes a personal differentiator,’ says Henrich. ‘Light as a medium becomes individual and this will reflect on the luminaire as well.’ But because of the standards in the commercial sector, the pace of development will be slower than in the home, he adds. But Davis believes the industry as a whole could do more. ‘Much of the lighting industry is stuck in a “this is the way we do things” mentality’, she says. ‘We have the potential to change everything about the practice of lighting design. New technologies give us great freedom, but it’s up to us to leverage that flexibility.’ A new wave of LED luminaires look like they have been developed by Apple

STATE OF THE ART TECHNOLOGY
SUPERIOR DESIGN ARCHTIECTURAL LINEAR LED LIGHTING
Let’s give the green light to
If the food industry can come up with clear, simple labelling to show what’s in its products, so can we, says Paul Taylor
on’t get left behind in the LED lighting revolution – that was the tagline of the recent conference in London on the future of lighting fixture design. Top of the agenda was how we all negotiate this oncein-a-century transition to a new light source. But while we in the industry are rushing to keep up, shouldn’t we be worried about leaving someone else behind – the customer? The LED industry continues to develop relentlessly, releasing new products on a monthly basis, making standardisation all but impossible. It can be hard enough for people working in the industry to know what’s what, let alone the poor soul still trying to find a 60W bulb for their laundry room. If there can be this much confusion and agenda-setting around what a good lighting product is inside the industry, what chance does anyone outside have?
68 | www.luxreview.com.au | 2013 Volume 1 Issue 1
Well, we can help them. On the road to LED enlightenment lies a golden opportunity for the industry to release the shackles of the old technologies and standards (measuring light output in watts springs to mind). We have a chance to educate rather than subjugate the customer.
Informed decisions But how do we do this when we’re struggling to adapt to LED technology ourselves? The green agenda has forced us to adopt energy efficiency ratings labels much like those seen on fridges and televisions. The upcoming package labelling standards will let consumers make informed decisions about efficiency, lifetime and power consumption. But this will not necessarily guarantee that they get a product that is suited to their application. Buying a light based on efficiency is like buying a car based on its milesper-gallon figures. You wouldn’t make a decision without going for a test drive, so why light your home with a source you haven’t got a feel for? What about performance and quality? Lumen output? How the light feels in the space? Colour rendering? Colour temperature? Beam angles? Peak intensities? Flicker? Dimmability? Glare
rating? Leading/trailing-edge dimming? Dimming range? And that’s before even contemplating controls and their compatibility with these features, and before adding the increasingly proliferated LED and semiconductor industry into the mix. The number of lighting criteria that many customers aren’t even aware of is huge and they must be presented simply and impartially to improve the customer’s understanding of what quality light is. In doing this we should encourage the use of quality products that champion light quality and efficiency in equal measure. Understanding the thermal and electronic requirements of an LED can require a degree in engineering. Much like a computer processor, if an LED gets too hot, its life and quality will be cut short. Without comprehensive testing of LED lamps and luminaires as systems with all these variables in mind, it will continue to be difficult for customers to get the transparency required to choose a good quality product over a poor one.
How ratings migHt work for ligHting products
Light quality CRI, LED binning based on tolerances such as MacAdam ellipses that dictate the LED device’s closeness to the stated colour temperature, colour shift over life based on thermal performance testing, colour shift over angle based on LED, optical quality of beam and distribution. Performance Output in lumens, peak intensity, dimmability range and compatibility.
Trying customer patience During my relatively short time in the lighting industry I’ve gained the ability to bore and confuse the average person about these variables in a matter of seconds. This amount of time could be equated to ‘customer patience’. If a customer can’t absorb or understand the information in a matter of seconds, they will switch off and probably buy the cheapest product with a decent efficiency rating. That’s not the best way for the market to go for anyone involved. To convey the necessary information succinctly is a challenge, but with good design and regulations to enforce them it can be done well and implemented on a huge scale. When governments around the world make traffic-light labelling of foods mandatory, they do it for one reason: to help people make healthier choices. The labels are designed to fit and be legible on all packaging. If we tried to adopt a similar system for lighting products, what attributes would it take into consideration and what would it look like? Efficiency in lumens per watt, lifetime in hours and power consumption in watts are taken care of already, and that’s a good start, but things can always improve. What about carbon footprint during manufacture and distribution? Recyclability? Hazardous substances? And how do we expand on this to implement the performance and quality attributes mentioned earlier? Well, we first have to define the most important aspects of LED selection, lighting knowledge, eco-friendliness and compatibility features, so we can score any product based on light quality,
Ecology Lifetime in hours, efficacy in lumens per watt, recyclability of materials, carbon footprint including manufacture and distribution, and if the product contains hazardous substances that require special disposal.
performance and ecology. The sum of these indicators could then be condensed into a smaller colour-coded traffic light or battery-style graphic that is accurate, compact and – crucially – easy to digest for the customer. If weighted properly, these three key indicators could help customers understand the value of a quality lighting product. I’ve produced a couple of examples of how such a system would show the benefits of a good LED product with high-quality LED selection, attention to thermal design and efficient optics, compared with a cheaper, poorerquality product. As with energy labelling, the criteria would need updating periodically to reflect advancements in technology and encourage manufacturers to increase the quality, performance and ecological credentials of their products. As numerous recent studies have shown, the quality of artificial light sources can have a huge impact on health and wellbeing, not to mention the impact on the environment or the customer’s pocket. Prioritising and implementing labelling legislation would be difficult but, if it is done for the right reasons, it could benefit everyone in the long run and we could all look forward to a brighter future where quality is as important as efficiency. ● Paul Taylor is concept design engineer at Havells-Sylvania Europe

15 WAYS to save lighting energy It’s easier to get your lighting bills down than you think – if you know what products to use and how. Thorn Lighting sets out 15 ways to make big savings on the energy you use for lighting
horn developed its 15 ways to make energy-efficient lighting easy as part of its eControl framework, which is designed to make it easier to understand, specify, install and maintain good quality energy-
efficient lighting. The 15 steps now form a major pillar of Thorn’s consultation advice for customers who set out to minimise energy consumption. They are split into four areas: technology, control, application and environment, and are based on the
principle that implementing one or more of the 15 measures will help generate significant energy savings. Here, we’ve set out Thorn’s 15 ways to save energy, and a real-life example of a project where each one was put to use.
1 LAMP EFFICACY
2 BALLAST CLASSIFICATION
Ensuring the lamp efficiently converts electricity into light
Controlling the electricity supply to the lamp
ST JAMES’ PARK, NEWCASTLE, UK
Thorn’s Quattro LED has recently been updated to benefit from the latest LED light sources, which are fitted behind a low-glare optic. The lamp achieves over 76 lm/W, and is over 80 per cent more efficient than the fluorescent technology it replaces.
Compared with conventional gear, Thorn’s high-frequency (HF) electronic control gear, with an energy-efficiency index (EEI) classification of A2, can cut electrical energy use by as much as 30 per cent and also reduce parasitic power when the Quattro T5 luminaire is off. BOSCH CHINA SHANGHAI, CHINA

L’HIPPODROME DE LYON, FRANCE
70 | www.luxreview.com.au | 2013 Volume 1 Issue 1
The innovative optical design in Thorn’s Champion floodlight includes a zero cut-off light guillotine and an efficient elevated glass. This optical design improves output by as much as 10 per cent while achieving industry-leading light nuisance control.
SYSTEM EFFICACY Combining optical and thermal control in the luminaire
The small, modern Thorn Oracle S takes advantage of the latest white light sources and efficient sealed optics to maintain optimum performance.
WESTEX CARPETS YORKSHIRE, UK
DURHAM COUNTY COUNCIL, UK
5 PRESENCE/ABSENCE DETECTION Providing light only when it’s needed
With the right presence detector, even warehouses with high bay lighting can benefit from excellent energy savings when the space is unoccupied. Using absence detectors means the Thorn Hi-Rack luminaires must be turned on when entering the space – maximising energy savings.
6 CONSTANT ILLUMINANCE Making sure light levels remain correct throughout the maintenance period
Using digital dimming, Thorn’s Cruz luminaires take measurements from sensors in the ceiling to establish the task illuminance at desk or floor level and compare it to the required lighting level. If there is too much light – when the lamps are new, for instance – the luminaires dim to save energy. As the lamps age, the dimming reduces to keep the task illuminance correct.
STATION PLAZA HASTINGS, UK
FORTH VALLEY ROYAL HOSPITAL, LARBERT, UK
7 DAYLIGHT DETECTION Reducing waste light during daylight hours
Sensors built in to the Jupiter and Indiquattro luminaires sense the change in daylight in the space, and let the luminaires dim to save energy whenever there is sufficient daylight. Intelligent software ensures the lights do not react to short-term changes, such as the sun drifting behind a cloud for a few seconds.

ENGLISH INSTITUTE OF SPORT, SHEFFIELD, UK
CENTRE RETAIL PARK, OLDHAM, UK
TASK-SCENE SETTING Letting the user set scenes and adapt the lighting to different tasks
Using Thorn’s Titus Sport fitting in combination with switching, the correct lighting level can be chosen for a range of court uses, including netball, basketball, badminton, football and volleyball.
TIMED OFF Automatically turning all lights off during unoccupied hours
Indra’s Bi power controls let the light level reduce automatically when the amount of traffic falls late at night. The luminaires still provide enough light to navigate safely through the space, but save energy by lowering their output.
PORT OF LE HAVRE, FRANCE
TASK LIGHTING Lighting task areas with the correct amount of light
It takes immense skill and judgment to offload shipping containers, so it is essential that crane drivers have the right amount of light. The integrated light shield on Thorn’s Champion fitting ensures no light travels up from the luminaire or creates glare for the driver. It also still provides excellent lighting for the containers.

ÅRE SKI RESORT SWEDEN
ZONING Arranging lighting in sections according to usage patterns or task locations
Careful selection and lighting arrangements across several key sections of the resort’s slopes maximise lighting impact from the Mundial C luminaires, while minimising energy consumption in areas of lesser importance.
SPENNYMOOR FOOTBALL CLUB, UK
SHEFFIELD COUNTY COUNCIL, UK
Tailoring maintenance schedules according to product age, performance and environment
Eliminating light that does not hit the intended target
ELIMINATING WASTE LIGHT Tight control of obtrusive light ensures the light from the Champion luminaires is directed only where required, so the surrounding buildings and environment are not affected. Nearby residents will no longer have their front rooms lit up on match night.
When you have to maintain thousands of luminaires, it is vital to be able to check operation remotely. Thorn’s Oxane provides a long-life LED and driver and communicates with the local authority’s central controls when the lighting needs attention. In turn, this can significantly reduce maintenance requirements and costs as the modern light source and optics save energy.
DOLLAN AQUA CENTRE EAST KILBRIDE, UK
ENVIRONMENT GREAT LUMLEY, DURHAM, UK
VISIBLE SMART METERING Ensuring results of energy-saving actions can be seen
Even the simplest smart meter can highlight how much energy is being used, as it does in this installation using Thorn’s Oracle S with the Telea controls system. This simple communication means users can immediately understand the impact of their lighting decisions. In most cases, users will balance the need to save energy with the light they need for the task at hand.
15 REFLECTANCE Using light reflected from surfaces
It is vital in swimming pool lighting to make sure reflections in the water do not inhibit lifeguards’ view of swimmers. This can be achieved by using the ceiling’s high reflective properties to bounce light on to the pool. Thorn’s Troika fittings can be mounted in easyto-maintain locations and reflect light safely on to the task. Use of white paint helps maximise efficiency and avoids tinting the light as it’s reflected.

LIGHTING ECONOMIST RETAIL LIGHTING
Retailers must approach lighting design holistically
DavE TILLEy LIGHTING ECONOMIST
Who wants to be
average? Lux Review Australia’s numbers man Dave Tilley asks whether there’s any real basis for specifying average lux levels for retail applications
t has always been surprising to me that there is a disconnect in the lighting design process between the primary display lighting, ambient lighting and point-of-sale displays. I suspect the broad range of disciplines involved in the store development and construction process is responsible. There are architects, designers, consultants, visual merchandisers, shopfitters, furniture makers… Double trouble Each discipline will have a specific brief for lighting specification and design, but do they all combine to deliver a holistic lighting solution? Walk in to most Australian shops with point-of-sale illumination, and then look at the ceiling lighting. With few exceptions, the point-of-sale display will also be illuminated from the ceiling, thereby eliminating the benefits of local illumination. I am sure some retailers will argue that these two levels of illumination are required to enhance and promote the merchandise. But... why? If the point-of-sale lighting is designed and specified to provide adequate illumination, then secondary lighting from the ceiling is superfluous. Retailers talk about contrast, drama and
74 | www.luxreview.com.au | 2013 Volume 1 Issue 1
theatre, but continue to design lighting systems that will fail to deliver these characteristics. Average lux levels, still used by many retailers, are part of the problem. Retailers must reconsider their dependence on computer-aided lighting design and look instead at the sales environment as a holistic design. All the elements of lighting must be considered. What would happen if the point-of-sale lighting was specified first and the main lighting designed to support and complement the point-of-sale display units? Let’s take a simple example. Six 900mm display units with built-in illumination. This arrangement may have six 20W CMH or equivalent LED wall wash luminaires. An annual saving of $77 may not seem a great deal, but consider the saving on luminaire costs – six of them at $145 each adds up to $1,160, together with installation savings of

many retailers still believe sales will be higher if more light is projected into the shop. this is flawed thinking”
$500 adds up to a significant saving. If there are 50 similar areas or stores then the numbers begin to look very interesting. Installation savings for 50 stores add up to $82,000 and energy savings for 50 stores would be $3,900. As well as the financial considerations, if the point-of-sale lighting is designed to engage the customer, any extra lighting can only be a negative. Merchandise display furniture is designed to project the brand and display merchandise – and it is often designed in total isolation by a brand. Furniture is rarely lit by lighting designers, more often it is the furniture manufacturer that determines the specification. It appears that many retailers still believe that sales will be higher if more light is projected on merchandise, or into the shop generally. This is a clearly flawed thinking.

Ditching average lux levels in favour of a custom approach is not as radical an idea as some may think. For instance, Barry Ayling of the John Lewis Partnership in the UK has removed the ambient lighting from store design, relying on the display lighting, focused on the merchandise, to create general illumination for customer circulation. Break with tradition On the subject of wasted light, let’s examine two other basic examples where improved efficiency can be achieved by designing for the application: meeting rooms and offices. Imagine a rectangular meeting room illuminated with 32W fluorescent downlights, which operates for 3,000 hours a year (see tables above). The use of computer-aided design will often provide a higher lux level than needed. This is because the number of luminaires will have been rounded up and the design will be symmetrical. Even if the application design included a number of luminaires to illuminate artwork, or simply provide a feature, the savings would still be significant. The traditional approach has to be reconsidered. For example, offices are generally illuminated symmetrically with the same luminaire. But what is wrong with isolating the main work area from the circulation space using different luminaires and lux levels, or even introducing task lighting? The third option above uses two pendant-mounted direct/ indirect T5 luminaires. In some offices there is a combination of main work area, meeting space and sub-work areas (for filing or circulation, for example). Should lighting design continue to conform to what is accepted, or should space be illuminated to reflect various applications?
THE LIGHTING ECONOMIST’S VERDICT
spotlights like this one from Fagerhult can highlight displays and key areas
Economic pressures and the desire for business efficiency will inevitably drive a more holistic approach to lighting design. If lighting efficiency is really the goal for retailers and the commercial sector, traditional lighting design will have to be replaced with innovation and more creative lighting solutions. Average lux levels will have to be discarded in favour of custom approaches that focus on the application. Remember, if we keep doing what we have always done, nothing will change.

Top lighting consultant Alan Tulla sets his sights on corridor lighting in the first of his articles presenting alternative ways to light a particular type of space
THE BUDGET OPTION
ALAN TULLA TECHNICAL EDITOR
et’s look at an area badly in need of more attention: corridors. And for those of you who only read executive summaries: the 18W CFL downlight is dead. Although corridors do not present onerous task requirements, they are often illuminated for long hours. They don’t generally get any daylight and long corridors, especially, can appear gloomy. Installing movement sensors and dimming will make a significant difference to the amount of energy consumed. Take your pick The three options set out here are intended to show how the appearance and running costs of corridor lighting can vary depending on the method and choice of luminaire. The corridor I’ve chosen to look at is 1.8m wide and 2.8m high. The calculations are based on a 24m-long space to demonstrate luminaire spacing and light distribution patterns. All the designs achieve about 150 lx at floor level. Energy load is quoted per linear metre because, unless the corridor is very wide, you’ll only be using a single row of luminaires. www.alantullalighting.com
78 | www.luxreview.com.au | 2013 Volume 1 Issue 1
This design uses a conventional recessed downlighter with a horizontally mounted 18W compact fluorescent lamp (CFL). For our 24m corridor, the downlights are spaced at 1.2m intervals. Although CFL downlights may appear the same, their efficiency (in terms of light output ratio and delivered lumens per watt) can vary enormously. The unit used here is an old design and delivers just 39 lumens per circuit watt. This efficacy is way below the level recommended in much of the energy legislation in Europe these days. On the plus side the appearance is generally bright and uniform, although the upper sections of the wall are quite a bit darker than the floor. The colour of the walls will make a big difference to the appearance of this scheme. But it uses far more energy than our other two options and has no special features to commend it.
TECH SPEC Luminaire Typical off-the-shelf recessed 225-250mm-diameter downlighter with white bezel ring and horizontally mounted 18W CFL Optical control Specular aluminium reflector, no cover lens Arrangement 20 luminaires in a single row down the centre of the corridor at 1.2m intervals Maintained average illuminance at floor level 165 lx (100-150 lx on wall) Overall uniformity on floor >65% Electrical load 15W per linear metre Total equipment cost $1,180 Pros Inexpensive to buy and available everywhere with a large variety of embellishments and accessories Cons Heavy electrical load compared with other solutions. And it looks dull
THE LOW-ENERGY OPTION
This type of highly efficient LED downlight with precise optic finally marks the end of the 18W CFL downlight. The LEDs use less than half the energy of the budget option, produce almost the same illumination level and give better uniformity. This option also has the lowest energy and maintenance requirements of the three options. For an LED downlight, it has a wide beam and puts a lot of light on the wall. Typically, 100-150 lx is achieved at eye height and below. Inevitably – with a small, powerful source and specular reflector – there are some strong highlights on the wall but the corollary is that a degree of sparkle livens up the corridor.
TECH SPEC Luminaire Trilux Inperla C2 HR LED downlight emitting 2,000 lm Optical control Specular aluminium reflector, no cover lens Arrangement Eight luminaires in a single row down the centre of the corridor at intervals of approximately 3m Maintained average illuminance at floor level 155 lx (100-150 lx on wall) Overall uniformity on floor 75% Electrical load 8.7W per linear metre Total cost $1,700 Pros The best option for energy saving and maintenance Cons High capital cost
THE ‘MAKE AN IMPRESSION’ OPTION
This is my favourite way to light corridors. The scheme uses recessed asymmetric wall washers and the highest illuminance is on one wall. Most corridor walls nowadays carry notice boards. In prestige offices, the walls often have corporate art or graphic design. It makes sense, therefore, to put the greatest illumination on the wall. This scheme uses recessed mounted T5 fluorescent units at 3m spacing. Note there is no need to place the luminaires down the centre of the corridor. Placing the luminaires closer to the wall, at a distance of, say, 600-750mm, would highlight the wall even more but at the expense of uniformity. Hospitals will often offset luminaires in corridors, so any patients lying on trolleys on their backs don’t have lamps shining straight in their eyes. Visually, the scheme works well because it gives good vertical illumination.
TECH SPEC Luminaire Recess-mount Trilux Solvan C2-L RAX with 35W T5 Optical control Asymmetric semi-specular aluminium reflector, no cover lens Arrangement Eight luminaires in a single row Maintained average illuminance at floor level 210 lx (185 lx on wall) Overall uniformity on floor >60% Electrical load 12W per linear metre Total cost $1,270 Pros Stimulating, useful for highlighting Cons Uses more energy than the LED option

Jeremy Turner of FAB Controls and Alan Tulla take us through the dos and don’ts of LED dimming. To zero per cent… and beyond! of the mains sine wave to vary the RMS voltage delivery to the load. When you turn it up, more voltage is supplied to the lamp and it brightens. When you turn it down, less is supplied and it dims. There are two methods for cutting the sine wave: at the start (leading edge) or at the end (trailing edge). Before we make any enemies, it’s not our intention to judge the lamps themselves. What we’re looking at is combinations of lamps with different dimmers and transformers. The lamps mentioned in this article will perform fine – if you use them correctly.
Halogen should work fine, right? You wouldn’t expect many dimming problems with a normal tungsten halogen lamp, right? Think again. You can see from the oscilloscope reading (Figure 1, overleaf), this 50W halogen lamp is flickering like crazy when used with a leading-
ED technology should be perfect for dimming – it’s controllable, colourtuneable, efficient and comes on instantly – but the reality is different. In a new installation there are several ways to dim LEDs without problems – notably Dali, 1-10V and DMX – but retrofit LED lamps are often used with a phase-cut dimmer designed for oldfashioned tungsten lamps. Lots of existing dimmers won’t work with LED lamps and, because there are still no standards for LED dimming, even lots of those made for LED sources will only work reliably with the same manufacturer’s lamps. Combining LED lamps with the right dimmers and transformers is a minefield. The result is that, for a lot of users, LEDs don’t dim the way they should. They flicker horribly, cut out before they reach zero, dimming levels are unreliable or they fail early because electrical noise and capacitor discharge fry the components. With the LED retrofit market taking off big time, these problems aren’t about to go away. So the Lux Review Australia team got together a transformer, a box of MR16 and GU10 retrofit lamps, a phase-cut dimmer and an oscilloscope, and hooked up a few combinations to see what would happen. Phase-cut dimming is used in a typical rotary or slider dimmer switch – it works by cutting off part

edge dimmer. The problem is the insufficient load on the dimmer, which was designed for a higher minimum load than the 50W lamp provides. If we add a synthetic minimum load to the circuit, the dimmer is brought within its normal operating parameters, the lamp is correctly controlled and the sine wave is clean. Part of the reason we have a problem here is that there’s only one lamp on the circuit, but with LEDs you could have a number of lamps and they still might not give you the minimum load you need.
Don’t be Dim – Jeremy’s tips on getting LeD Dimming right
What about GU10s?
Even a budget LED GU10 lamp can dim with no flicker if used correctly. This LED lamp is only $7 and, despite its lower wattage, it works well. Generally you won’t have too many problems with GU10 lamps, which receive a modified version of the mains current. The manufacturer is able to work with a known supply voltage and how they perform comes down to the design of the power supply in the base of the lamp. The other reason these LEDs perform well is that they’re compatible with the dimmer we’re using. That doesn’t necessarily mean they will work as well with another dimmer.
Figure 1: Even good old 50W halogen misbehaves with the wrong dimmer
MR16s are a little more complicated. Because the lamp is not directly driven from mains voltage, a transformer must be used. But transformers were designed for the halogen lamp to provide the stabilisation circuit. Without it, the transformer cannot cope and could even blow up. To be successful, a zero-load transformer suitable for LED loads must be used. In effect, many MR16 LEDs are not a simple plug-and-play retrofit solution, so manufacturers supplying them should provide a suitable transformer alongside the lamp. Even a high-end product such as Soraa’s Vivid 12W MR16 flickers with a standard transformer (Figure 2). It’s not the lamp’s fault – the cause is a mismatch between lamp and the transformer. If we connect a zero-load transformer designed for the small load of an LED lamp, the transformer is stable and will provide a stable voltage to the LED. Even the sine wave produced by the transformer is not clean: small peaks indicate discharge from the smoothing capacitors inside the transformer. If we add another lamp, the dimming curve becomes clean and the lamps get brighter (Figure 3). This is because our dimmer does not perform correctly with the small load provided by the single lamp. With MR16 sources, lamp, transformer and dimmer have to match to get a good result. But watch out: the result seen with one lamp can occur with too many lamps. This is because of the large inrush current LEDs take when first switched

● Wherever possible, use a Dali, 1-10V or DMX system to dim LEDs. This allows the LEDs to be constantly powered, and dimming undertaken by a separate control cable. If phase-cut dimming is the only option (like on a retrofit project), try out the lamp and dimmer combination in advance. ● Don’t assume that paying more for an LED lamp means it will dim correctly. ● Match the right lamp to the right transformer. Look for zero-load support. ● Load your dimmer properly – too little or too much and it won’t work right. ● Make sure you have the de-rating figure for your LEDs. ● Don’t rely on paper predictions of which lamps will work with which transformers and dimmers – try them out and see. ● Don’t trust anything you read. The lack of dimming standards means some combinations that should work don’t, and others that shouldn’t do. ● Ask your lamp supplier for a list of compatible equipment. ● Remember: even if a lamp appears to be could still be shortened functioning OK, its life if it’s being used wrongly.

on. Be sure to check if the LED manufacturer issues a de-rating figure for the dimmer – without this you can get caught out.
Learning the lesson
82 | www.luxreview.com.au | 2013 Volume 1 issue 1
Try each lamp (transformer) and dimmer combination yourself to know if it’s going to work. Even lamps that seem to be working OK (they’re at the right brightness and aren’t flickering) may damage your dimmer and LED in very short time due to electrical noise and capacitor discharge. If you don’t have an oscilloscope, you won’t see this. From a buyer’s perspective, it’s really helpful when manufacturers publish lists of equipment that’s compatible with their lamps – so customers and sales staff know what they’re dealing with.

Lux recommends Car park lanterns
LANTERNS Alan Tulla gives his verdict on the latest LED luminaires for car parks and outdoor urban spaces
A number of factors will affect where you place the columns
utdoor car parks vary enormously in size and layout, but they all have three common requirements: people who use them must be (and feel) safe; roadways and vehicles must be well illuminated without any dark areas; and luminaires must have well-controlled optics to minimise upward and stray light. Large and small Small car parks are often illuminated from the perimeter to keep installation costs down, both on cabling and on physical protection for the columns inside the parking area. The disadvantage of this method is that, because of the throw needed in wide car parks, taller columns are needed compared with those used in a central location scheme. Taller columns also have a greater visual impact during the day. Perimeter schemes tend to produce spill light rearwards into adjacent areas. This is especially relevant to car parks bordered by housing. Large car parks often use columns inside the area. Centrally located columns need a physical barrier to protect them from vehicle impact; adding to their cost. However, they have the advantage that light can be directed in all directions from one position, thus keeping the number of columns needed down. For smaller areas, a single lantern with a symmetric (round) distribution is sufficient. For larger areas, it may be necessary to mount several lanterns in a star arrangement on top of the column. In this case, a ‘streetlighting’-type distribution (long and narrow) might be a better solution. This also enables wide spacings to be used along the driving and walking routes.

ABAcus orIon When we asked Abacus where we could see an installation of these lanterns, the answer was ‘at a supermarket near you’. There is a complete family of these posttop lanterns from 450W metal halide and 8m mounting heights to an 80W LED version more suited to 5m mounting heights. A ‘flat glass’ version is available, suitable for E1 environmental zones where light pollution must be minimised, and the optics can have a square or asymmetric distribution. The advantage of such a wide range is that you can retain a consistency in appearance for car parks of any shape or size.
Gets the job done
PHILIPs meTronomIs This latest range of architectural post-tops is designed for urban open spaces. The basic form is a clear conical/tubular bowl with the LEDs housed in the top. The large, clear bowl and minimal top make this unit unobtrusive. But we preferred the way it looked when it was off to when it was on. The Metronomis can be used with almost any type of column – wood, steel or aluminium to suit the surroundings. Light output is 2,000-9,500 lm (20-120W). Claimed lifetime (L80F10) is 100,000 hours for the Greenline version and 70,000 for the Economy, so this unit should last and last.

Reviewed: car park lanterns TRT ASPECT
ACUITY HOLOPHANE D SERIES
This is a new range of LED lanterns from Thorlux’s road and tunnel division, TRT. There are four beam spreads and 10 power options so there is bound to be one that meets your needs. The Aspect is best suited to lighting from the perimeter and one of the beam spreads mimics that of a conventional floodlight. One interesting feature is that the lantern can have a negative tilt – so when you retrofit it on to an inclined outreach arm, you can still achieve an environmentally friendly beam with no upward light. There are decent-sized heatsink fins on the top and, being open at the ends, they allow rain to wash away any dirt.
This slim, robust, lantern is one of the best in terms of efficiency, life and choice of power/lumen configurations. You get six lumen packages from just two body sizes. Although it may look like a conventional streetlight, there are three optical settings that make it suitable for car parks. Like some other quality lanterns, the beam shape comes from ‘layering’ optical lenses so that, in the rare event of an LED failing, you are not left with a dark patch. For techies, it’s reassuring to see that the LED life data is published in line with IEC PAS 62722 and 62717 standards.
A new look from a new name
CREE LEDWAY ROAD
It may never win a beauty contest, but this LED luminaire from Cree is well worth considering. The standard version is available from 50 to 272W with a choice of six different beam distributions. It means that you can illuminate just about any configuration of road and parking bays with an identical-looking lantern. There is also a range of control options available from occupancy sensors, 1-10V, to powerline systems. The standard version is 4000K, but 3500 and 5700K options are available. And the latest incarnation of Ledway, available now, hits 104 lm/W.
Wow? Maybe not, but this is certainly a beautiful piece of engineering. Apart from its looks, we like the driver warranty of 100,000 hours and a rated life for the LEDs of L90, B10 when running at 350mA. They will also give you a special warranty for operation at an ambient temperature of 45°C. If you want more light output from a particular lantern, you simply flip a DIP switch on the driver. There are a variety of optical distributions and power outputs. You get over 100 lm/W at the lower power ratings and a very respectable 88 lm/W for the high-output 147W version.

In simple terms, it is a very narrow angle floodlight, although ‘floodlight’ is the opposite of what it does, writes technical editor Alan tulla. Why would you need a very narrow angle beam of light? There may be no convenient location to mount a floodlight, access may be difficult or you may want to light an object and nothing else. Perhaps the floodlight must be out of harm’s way, or you may need minimal spill or light pollution. The Stanley Electric Ultra Narrow Light Angle LED Floodlight has a total beam width of just three degrees with a peak intensity of over 410,000cd. For the non-technical, this means you would get over 35 lx on a statue – with no spill light on the column – from 100m away. Not bad. Alternatively, you can achieve emergency lighting levels of illumination from well over a quarter of a mile away. This illumination would easily stand out in a moonlit landscape. Best of all, this outstanding performance is achieved from a unit less than 250mm square, 50mm deep and with a power consumption of just 21W. The secret is in the nine precision lenses, originally derived from highpower car headlamps – a Stanley Electric speciality. It’s rated at IP65 and the 5000K LEDs have a stated life of 40,000 hours at L70. What more can we say? It’s a knockout.

The next generation of MR16 and GU10 lamps is driven by LEDs
RAISING THE BAR Nearly 100,000 GE lamps have been installed by UK pub and restaurant chain Mitchells & Butlers (owner of All Bar One and O’Neill’s) in a massive retrofit project. GE’s Energy Smart GU10 LED lamp is designed to replace 35W halogen while using only 4.5W. It can dim to 10 per cent. With big energy savings and long lives, the lamps replace halogen lamps in accent, display and general applications in commercial, industrial or residential environments. www.gelighting.com
LOOK, NO DRIVER Enilight’s new GU10 may look similar to others, but it’s fundamentally different – there’s no driver. This lamp runs on mains power, thanks to an AC chip from Samsung. In fact, Enilight’s entire Iviti range of lamps will be moving to AC in the next three months, the company says. Electronic drivers are often the weak link in LED products, so Enilight’s development aims to take the driver out of the equation, sidestepping those irritating problems of compatibility, dimming and early failure. The first driverless GU10s will be available in 3000 and 4000K versions, producing 390 lm from 6W. www.enilight.co.uk
SHINING EXAMPLE Megaman is known for its great quality, great value lamps. Its new dimmable 8W MR16 comes in colour temperatures of 2800 and 4000K and a choice of two beam angles – 24 and 36. With an output of 450 lumens, a CRI of 85 and a life of 50,000 hours at L70, it’s built to last. megamanlighting.com
OFF THE SCALE Verbatim’s latest MR16 lamp uses an unconventional colour mix, with red, green and blue phosphors applied to a violet LED dye (instead of the usual yellow phosphor and blue dye). The VxRGB Vivid Vision lamp is designed for applications that need the highest quality light – such as galleries and museums. In fact, Verbatim believes it shows colours so vividly that the standard scale of colour rendering isn’t adequate. ‘The CRI is not the measurement that is relevant for this type of product,’ says business development manager Jeanine ChrobakKando. ‘It is down to customer needs in utilising the characteristics of the light in making objects appear more vivid.’ www.verbatim.com
INSIDE STORY Havells-Sylvania’s latest MR16 lamp features the company’s CoolFit technology, making it suitable for use in enclosed fixtures. The lamp monitors its own temperature, and if it gets too hot, it automatically dims itself to reduce the heat generated and ensure long life. The 8W lamp is also dimmable and comes in a ‘true fit’ size, so it should fit into the same fixtures that used to accept halogen lamps. www.havells-sylvania.com
BRIGHT STAR Forge Europa’s GU10 emits 670 lm. Designed to replace a 50W GU10, it achieves 70.5 lm/W with a CRI of 80 and 1,091 cd from the 36-degree beam. Forge uses Cree chips to ensure high standards. Grant Huck, business development leader, says: ‘There is a trend of disparity between actual 50W halogen flux and the flux of claimed 50W LED equivalents. Our challenge was not insignificant, especially considering the size and market position of our competition. We aimed to raise the bar.’ www.forge-europa.co.uk
ACCESSORISE YOUR LAMP Soraa’s ‘Snap System’, lets users magnetically attach beam shapers, colour filters, louvres, snoots and grates to its LED MR16 lamps. By attaching accessories directly to the lamp, users can customise their lighting without relying on bulky and costly fixtures. It’s possible partly because LED lamps emit so much less heat than halogen, and accessories can be made from innovative materials. Soraa CEO Eric Kim calls it ‘the Swiss Army knife of highperformance lighting’. www.soraa.com

Efficacy Efficacy explained To understand efficacy, efficacy, you must understand lumens, watts and power factor.
DR GARETH JONES LIGHTING & LED SCIENTIST
What is efficacy? There has been a lot of confusion in the lighting industry about efficacy and what it means. A straightforward way to express the efficacy of a product is the amount of useful light, in lumens, that it produces compared with the amount of electrical power, in watts, that it consumes in its circuit (including the light source and anything else that draws power from the circuit such as a ballast or driver). This is called useful lumens per circuit watt – a widely used term that sounds simple, but turns out to be rather complicated, and can be used by different suppliers to make wildly differing claims. What is a ‘useful lumen’? Let’s start breaking it down. Lumens are determined by what the human eye perceives, and that depends on how the eye responds to light. Efficacy is literally in the eye of the beholder. We determine it by measuring spectral information using a spectrophotometer, or simulating it using a photometer, and converting the result into lumens. But we’re not just talking about lumens, we’re talking about useful lumens, and whether or not a lumen is useful depends on the context. Lamps and luminaires can be direct or indirect and have characteristics that are directional or non-directional. By classifying the type of directionality we can work towards a meaningful measure of the number of lumens that are ‘useful’ for a directly illuminated task.
Lamps that have good efficacy for lighting a task focus light into a 90-degree cone
92 | www.luxreview.com.au | 2013 Volume 1 Issue 1
In Europe, the European Union has defined a ‘directional lamp’ as one that has at least 80 per cent light output within a cone of 120 degrees (defined by a solid angle). Any other lamp is ‘non-directional’. For a non-directional light source, the useful lumens figure is the total amount of luminous flux coming from the source. For a directional light source it’s a bit more complex. The European Union’s latest approach is to promote lamps that have good efficacy for lighting a task, and therefore focus the maximum amount of light into the useful 90-degree cone (defined by a solid angle). The system then measures only the light captured in this 90-degree cone and reports it as useful lumens. What is a watt? Now we’ve pinned down useful lumens, let’s talk about watts. Light sources can be battery operated or driven by AC or DC mains power. DC power is particularly efficient when coupled with LED lamps and luminaires, and is becoming more important. An important consideration for the luminous efficacy calculation is that the correct watts values are used for the product being tested. The efficacy of a self-ballasted lamp will be determined by the total power drawn from the mains supply. That means that the power in watts will include the conversion from high-voltage AC to lower-voltage DC and then to a constantcurrent driver circuit. Each step has inefficiencies built in which reduce the overall efficacy. Another lamp may be designed to be purely DC driven, without conversion. An assessment might give the impression that such a DCpowered product is more efficient, but remember that AC power will have been converted to DC power somewhere else down the line (this will become more interesting when homes and buildings start to be powered directly from mains DC supplies). This causes confusion and it is important to check whether product performance figures are derived from a DC or AC supply. There are many elements that make up solid-state lighting and most of them affect efficacy (see above). As we’ve seen, useful lumens per circuit watt is what we’re really interested in, but some manufacturers may use datasheet values for the LED package, which may not represent the lumens emitted under
Don’t be afraid, the doctor will explain all…
Many factors limit the efficacy of solid-state lighting
the conditions in which the source will be used. The LED package can be tested in a number of ways. The first is the quick screening test performed on the LED, in which a current pulse is applied to the LED and the light output is measured. This is the ‘cold’ lumen test and results in the highest lumen value that can be achieved. The second way is to apply constant DC current to the LED with the case at a temperature that represents the temperature that may be reached inside a lamp or luminaire. This is the ‘hot’ lumen value and is much closer to the value that the LED package will emit in real world conditions. Specifiers should always make sure that ‘hot’ lumens are used as the starting point for any discussion of luminous efficacy. Of course most LED lamp or luminaire products have lenses or reflectors on top of the LED. These optics introduce losses and so the number of lumens emitted from the LED will not be the same as the number emitted from the lamp or luminaire. The driver circuitry will also introduce losses and further lower the efficacy. So, manufacturers can make a number of different claims, but if specifiers ask the right questions, they should get the right answers. A group of lighting bodies in the UK has developed guidelines for specification of LED products – bit.ly/ledspecs – and I’ll discuss the questions specifiers should ask about product efficacy in more detail in a future column.

People who work in lighting use a lot of technical terms. Here’s what some of them mean...
Colour temperature describes whether a light source appears ‘warm’ or ‘cool’ – indicated by the correlated colour temperature (CCT). Lamps with a warm appearance have a CCT of 2700-3000K, and are considered appropriate for domestic settings; cooler lamps might be 4000K, and are used more often in offices and shops. The higher the colour temperature, the ‘cooler’ the appearance. Don’t ask.
Leadership in Energy & Environmental Design – LEED – is a programme from the US Green Building Council that has been widely adopted in Australia to score buildings for efficiency and sustainability. LEED scores are are also used in places like the Middle East, as they are flexible enough to apply to any project.
The Digital Addressable Lighting Interface is a protocol for lighting controls and dimming agreed by major manufacturers. It is set out in the international standard IEC 62386. A Dali working group, set up by manufacturers and institutions, promotes Dali technology and applications.
Short for colour-rendering index, CRI is the ability of a light source to show the colours of objects accurately. The higher the CRI, on a 0-100 scale, the more accurately the lamp will render colours. Lamps with poor colour rendering will distort some colours, so you may end up with brown socks when you wanted green ones.
High-pressure sodium lamps (commonly called SON lamps) are gas discharge lamps that use sodium vapour in an excited state to produce light. They are often used for streetlighting. SONs produce a yellow light and have poor colour rendering. But they are efficient, often reaching efficacies of about 100 lm/W. Higher-powered 600W versions can reach an efficacy of 150 lm/W.

Circuit watts (Wcct) means the number of watts used to power an entire circuit, including the control gear or driver rather than just a light source or luminaire.
LOR Light output ratio – the percentage of light emitted from the light source that makes it out of the luminaire. An LOR of 70 means 30 per cent of the light from the lamp is lost inside the reflector and light fitting. But there’s some debate about how to apply LOR to LED luminaires because of the directional nature of light emitted by LEDs.
PIR Short for passive infrared. PIR sensors are electronic sensors that measure infrared light radiating from objects in their field of view. PIR sensors are one of the main technologies used for presence and absence detection, turning lights on and off when people are or aren’t there.
CFL Popularly referred to as energysaving lamps, compact fluorescent lamps have a poor image because of perceived deficiencies in colour, power and the time it takes them to reach full output. But massive improvements have been made in all these areas thanks to substantial investment by the big lamp manufacturers.

The kilowatt-hour is a unit of energy equal to 1,000 watt-hours. That’s what a 1,000W device uses in one hour – or what a 1W device uses in 1,000 hours. It’s the ‘unit’ that shows up on your electricity bill.
Lux is the international unit of illuminance – a measure of how much luminous flux (in lumens) is spread over a given area (in square metres). In other words, it tells you how much light is hitting a surface. 1 lm/m2 equals 1 lx. Multiply an illuminance figure in lux by an amount of time in hours and you have a measure of exposure in lux hours – useful if you’re looking after delicate objects or surfaces that can’t be exposed to too much light.
An IP (index of protection) rating tells you the amount of protection a luminaire or other piece of equipment has against things getting in – including dust, dirt and water as well as hands and fingers. For example, a fitting rated IP22 will prevent the insertion of fingers and will not be damaged if exposed to dripping water.
● Engaged audience ● More opportunities to be seen
Zhaga is an industry-wide co-operation to standardise specifications for the interfaces of LED light engines. The aim is for light sources from different manufacturers to be interchangeable, so that luminaire makers and end users aren’t tying themselves to any one supplier. But critics say Zhaga doesn’t help buyers, and discourages innovation.
