iven that we’re always talking about how to promote the understanding of lighting to fellow design professionals and the public at large, it’s ironic and unfortunate that the only headlines

it grabs quite frequently nowadays are invariably of the negative sort (see Truth or glare? p10). When LEDs aren’t making you go blind, they’re being switched off altogether and causing crime waves (see News, p5). I’m obviously being simplistic to make a point but then so are newspapers, often failing to convey the full complexities of the case. It’s easier to demonise LEDs themselves rather than fully examine how they’ve been installed – column height, colour temperature, glare control and so on – and determine whether that is where the fault lies. Where switch off is concerned, it has always been a blunt instrument – dimmability and responsive fittings clearly offer a better solution in urban environments – and could well be a contributing factor to higher accident rates in those areas. But we don’t yet have the full facts, and statistics can be played a number of ways. This is why the Lanterns project is so important (see p14) and why those local authorities that haven’t yet signed up should do so. It’s crucial that we get as full a national picture as possible. Lighting professionals at least should be armed with the truth of the matter. Jill Entwistle Editor

CPRE backs dimming

where they’re not appropriate, but why shine bright lights on residential streets, quiet roads and open countryside throughout the night when it’s not needed?’ said CPRE Dark Skies campaigner Emma Marrington. ‘Genuine dark starry nights are becoming harder and harder to find which is why councils should take action to control it now. Light pollution blurs the distinction between town and country, ruins the countryside’s tranquil character and denies us the experience of a truly starry sky.’ The proportion of people living with severe light pollution in the UK is growing according to the CPRE. Its most recent annual Star Count survey shows that 59 per cent of the 1000 people who took part could see 10 stars or fewer within the constellation of Orion, the worst result since 2011.

Back to school 2015 The ILP and Light School have renewed their partnership for the 2015 event which takes place from 10-12 February next year at the Business Design Centre in London. Presented by Light Collective and hosted by the Surface Design Show, Light School is a forum for influencing and educating architects and interior designers about lighting design and lighting products. ‘The key purpose of the ILP is to promote excellence in all forms of lighting,’ commented Richard Frost of the ILP. ‘We therefore give our full support to Light School in influencing and educating the design community into the best use of light.’ The ILP will be playing an active role in developing the School Room programme of

Lighting Journal June 2014

seminars and presentations. ‘The ILP’s involvement reflects the importance of Light School’s mission for the lighting industry to increase its communication with architects and interior designers,’ said Sharon Stammers, cofounder of Light Collective. Light School has three elements: School Room, Product School and School Newspaper. More than 400 architects and designers attended the first year’s programme of talks by leading lighting designers. All sessions were completely full, so the Light School is looking into having a bigger space for the 2015 event. Surface Design Show and Light School were attended by more than 4000 professional visitors in February 2014.

‘We are concerned that almost six out of 10 people who took part in the Star Count saw fewer than 10 stars in the Orion constellation,’ said Marrington. ‘This suggests they have severe light pollution in their area. The fact that 96 per cent of respondents cannot experience truly dark skies where they live shows just how badly light pollution affects our lives.’

A new report by the Campaign to Protect Rural England backs local authority measures such as partnight lighting and dimming as a way to reduce light pollution. The report, Shedding Light – a survey of local authority approaches to lighting in England, says almost a third of councils are switching off street lights, typically between midnight and 5am, and almost half are dimming street lights in their areas. Dimming schemes are significantly more popular than switch-off schemes with residents. Shedding Light makes nine recommendations, including preserving dark skies by having a presumption against new lighting in existing dark areas, and allocating lighting zones to help determine where street lights should and should not go. ‘We’re not advocating changes

The IALD held its 100 Watt Challenge in London for the second year running. Five of the UK’s top architectural lighting consultants put their creative schemes on display during the week-long competition – one a day – organised by IALD UK projects manager Emma Cogswell, Stuart Knox of Architectural FX and Simon Thorp of LAPD. The teams have to light a house – the House Next Door in Stoke Newington – which comprises six rooms and four different levels, using a maximum of 100W of LED light tape. ‘The limit was arrived at because until relatively recently it was commonplace to use a 100W light bulb in every room of a house,’ said Cogswell. ‘Now designers are able to light an entire house with just that wattage.’ The teams taking part were BDP, DPA Lighting, Light Bureau (one of whose designs is pictured), GIA Equation and Paul Nulty Lighting Design. Sponsors who supplied the equipment were Architainment, Architectural FX, Eldoled, and LED Linear of both UK and Germany.



Essex switches back on in controversial area

A decision temporarily to suspend part-night lighting on four streets in Brentwood, Essex, has once more thrown the media and political spotlight on links between street lighting and crime. The four streets in Communities Secretary Eric Pickles’s constituency suffered what The Daily Telegraph called a ‘crime wave’ in April when a car was broken into, a house was burgled and a motorcycle was stolen, according to local reports. Residents blamed new part-night lighting, which was subsequently suspended in the Pilgrims Hatch area, at the request of Essex Police for the sake of ‘public reassurance’, with lighting continuing past midnight to 5am, until 26 May. ‘This suspension was approved by us after a request from the police in accordance with the wellestablished procedures which were set up between us as part of the implementation of the Part-Night Lighting scheme,’ said Rodney Bass, cabinet member for Highways and Transportation. ‘Since last December, they

have been invoked in three localised situations, including the most recent at Brentwood, and twice at the initiative of the County Council across the whole of Essex when we faced the threat of a hurricane and a tidal surge. ‘We are also monitoring crime and accidents in the areas covered by the scheme,’ he added. ‘There has been an increase in the number of burglaries in the Pilgrims Hatch area over the past few weeks,’ said Brentwood district’s neighbourhood policing inspector, Scott Kingsnorth. ‘As a preventative measure we have asked for the street lights in that area to be kept on. This is just one tactic we are using to manage this problem in this area. There is no link to prove that the street lights being switched off led to the rise in burglaries.’ ECC-owned street lights ‘that don’t meet the exception criteria have been turned off between midnight and 5am,’ except in parts of Epping Forest where lights are switched off between 1am and 6am, the council says. By operating part-night lighting it saves more than an estimated £1m a year compared to an annual street lighting energy bill of £4m in 2010/2011 (see sidebar). Exemptions include ‘sites where the police can demonstrate that there is likely to be an increase in crime if the lights are switched off during part of the night or that there will be a decrease in crime if the lights are switched back on’. However, ‘the general experience in parts of Essex

has been that a reduction in street lighting has not led to any noticeable increase in crime,’ said Kingsnorth. ‘We will monitor with interest the consequences of any changes in the patterns of street lighting for any impact on both crime and peoples’ fear of crime,’ he continued. ‘We will continue to work very closely with Essex County Council and other agencies to ensure that we all keep reducing crime across the county.’ The story gained national traction when the Telegraph claimed that Pickles (pictured) – who it dubbed the ‘Minister for Darkness’, after an earlier defence of partnight lighting – had been overruled by Essex Police. ‘Eric Pickles faces embarrassment after police ordered street lights to be switched back on in his constituency, weeks after he insisted darkening streets cuts crime,’ the paper said. Shadow communities secretary Hilary Benn raised the issue of part-night lighting in the House of Commons on 13 May, when he asked what assessment Pickles had made ‘of the link between street and ambient lighting and the incidence of burglaries’. ‘There may be some roads where lights could be dimmed in the very early hours, saving taxpayers’ money. However, this should be a local decision by elected local councillors, reflecting local circumstances, especially in relation to any concerns about crime,’ replied Parliamentary Under Secretary of State Brandon Lewis.

London’s Hackney on 27 June 2014. The event is part of a movement originally based on bringing a ‘hacking philosophy’ into the lighting industry. A group of like-minded lighting individuals share creative ideas and knowledge with a view to solving a problem (creating new LED lighting products). The aim is to encourage higher levels of innovation in an entertaining way. ‘It’s a perfect blend of art and science and very much a part of the institution’s architectural lighting philosophy,’ said Mark Ridler, VP architectural lighting.

‘Equally, not every neighbourhood wants street lighting, as some communities, especially in rural areas, value dark skies,’ continued Lewis. ‘We believe that councils should listen to the views of their local residents, and then adopt appropriate local policies based on the neighbourhood, the precise location and the usage of the road or street.’

ECC boasts biggest CMS Essex County Council claims the world’s largest wireless street lighting central management system, following the 125,000th connection to its lighting network. Essex-based Telensa’s Public Lighting Active Network (PLANet) system cost £6m but the council expects to reduce its street lighting energy bills by roughly £1.3m a year through part-night lighting. ‘Telensa’s system has fully met our expectations and has been deployed across the county’s 12 districts in two years and within budget,’ said Rodney Bass, cabinet member for Highways and Transportation.

The first event was formulated by Joe Vose from Light Bureau, who organised it in conjunction with Light Collective, supported again by Mike Stoane Lighting. It also has the backing of other suppliers including Xicato, Soraa, Mode and LED Linear which have donated materials. MSL is currently preparing 30 ‘kits’ of components to send out to interested lighting designers. Anyone in the ILP interested in taking part should email Craig Scott at MSL:

The accident was captured on video by a photographer from the Coventry Telegraph whose offices were opposite the incident site. Graham was left with a broken finger after the column narrowly missed his head and landed on the handlebars of his bike. Workers from Lighting Coventry – a partnership between the city council and Balfour Beatty – were carrying out an emergency replacement of a column considered dangerous because of corrosion to its base, but it came free from the harness they were using to winch it out. Graham plans to take action, he said. ‘Apart from the loss of earnings, they’ve also destroyed a brand-new bike,’ he told the Telegraph. ‘We have of course apologised to the cyclist and ensured that he received immediate medical attention,’ said a spokesperson for Lighting Coventry. He added that Lighting Coventry would take appropriate steps once the full facts were established.

LIGHT Minded... Richard Hayes of 42 Partners on the complexities of the S/P ratio and why a shotgun approach to high CCT LEDs must be avoided

It is well established, backed up by science and research, that there is a link between high S/P ratio sources and the perceived brightness of a scene. The CIE accepts that at mesopic levels, where road and amenity lighting fall, the photopic content of light does not tell the whole story. In the UK, the road lighting standard BS5489-1 has been amended to allow designers to use a mesopic factor to increase the effectiveness of sources with a high S/P ratio; interestingly, EN 13201 (a EuroNorm) does not allow reductions in illuminance based on S/P ratios. The factors allow a maximum reduction of 18 per cent at a target illuminance of 15 lux, increasing to a 45 per cent reduction at a target illuminance of 2.0 lux. There is research that suggests that these factors are very conservative; several groups have found that at a high S/P ratio, detection of objects and movement outside of the foveal region can be much greater than is allowed for in the CIE model. Experiments by Dr Sam Berman, former head of the lighting group at the Lawrence Berkeley Laboratory, have shown that the size of the human pupil under normal (what is considered photopic illuminance) lighting conditions is much more closely related to the scotopic content of the light. There are potential energy savings to be made in normal interior lighting by using higher S/P ratio sources, and again this points to a potential to further reduce energy usage in amenity and street lighting. Anyone who has stood at two similar sites (as I have done), lit by HPS and metal halide lighting with similar photopic illuminance, cannot help but conclude that there is more going on here than can be explained by the currently applied mesopic functions. With some like-minded colleagues, in 2005 I conducted a trial in Leicester at a DeMontfort University site. We managed to find a pair of crossing roads – Mill Lane and The Gateway – where it was possible to replace the 150W HPS lighting on one axis (S/P ratio 0.63) with a similar luminaire using 70W CDM–T (S/P ratio 1.3). Effectively we reduced the illuminance by more than 50 per cent.

Lighting Journal June 2014

Observers could stand at the crossroads and see both roads illuminated at the same time. The trial was monitored and users asked for their opinions on the lighting. Overwhelmingly respondents felt that the ‘white light’ axis was lit to a slightly lower level than the HPS axis, but all respondents preferred the white light axis. Unfortunately we could only hold this condition for a short period of time, and we had to curtail the trial before we could collect as much data as we would have wanted. Berman’s research can also be applied to interior lighting. In a trial at Intel in 1995, changing interior illuminators from fluorescent of 3500K (S/P ratio 1.5) to a lamp of 5000K (S/P ratio 1.95) allowed a drop in average illuminance from 55 foot candles (590 lux) to 45 fc (480 lux) with a resultant energy saving. Users of the space felt that the area was still slightly overlit using the 5000K lamps. LEDs, the industry answer to all questions, are adding a further layer of complexity. As LEDs of more than 5000K CCT are much more efficient than LEDs of 3500K, this has led to some exterior installations of street lighting at more than 5000K. It is the blue content of the LED light at high CCT that gives LEDs a high S/P ratio – simplistically, high blue in LEDs means high S/P ratio. There is evidence that high blue content lighting can cause melatonin suppression in humans, resulting in disturbed sleep patterns. To complicate matters further there is evidence of a link between melatonin suppression and increased cancer risk, hence the scary headlines. There is a gathering body of comment that says, whatever the risks, the general public simply do not like the effect of LED lighting at high CCT and there are welldocumented complaints about some of these installations. Some commentators are asking for street lighting using LEDs at more than 4000K to be banned. The lighting industry can’t afford to ignore the potentially large energy savings to be made by taking advantage of high S/P sources, but this should not mean a shotgun approach to rolling out 5000K LEDs where they are just not appropriate.



LIGHT Hearted Glynn Hook, principal lighting engineer with Staffordshire County Council, reflects on his lighting legacy Reaching the milestone of 25 years as a local authority lighting engineer this year – can it really have been that long? – my mind has started to wander back and reflect over the past two and a half decades of my career. Legacy is a word that seems to have been used a lot these past few years, so I have been considering what lighting legacy I have been leaving in my wake. Well, long before it became a buzz phrase, I like to think that I have always tried to put the right light in the right place at the right time. It’s what lighting engineers do, isn’t it? I’ve ensured that roads are illuminated to the right levels, removed inefficient lighting, trialled new technology (good and bad), ensured that what stock is out there is well maintained, retained good data records and, wherever possible, positioned lighting columns and signs so that they cause least hindrance to the public. It has been very fulfilling to deliver viable, cost-effective solutions for non-standard installations, and also to have worked on a range of architectural schemes. I’ve also influenced others along the way and persuaded them that wasteful, poorly designed schemes should not be implemented. So when I travel round my home town, where I’ve managed the lighting for the past quarter of a century, I recall the numerous lighting schemes that I’ve had an involvement in, noting the different lamp types, all of which in their day were considered to be the next big thing. On the quiet, I must admit that I’m actually quite proud of the impact I’ve had so far, especially where the nonstandard installations are concerned. Ultimately, I think that this ‘Town Hall mandarin’ (a quote from the local paper from a few years back), with his obligatory council clipboard, has not been leaving a bad legacy.

Street lighting

Truth or glare? Histrionic headlines have painted a misleading picture of LED street lighting. Focusing on Hounslow, Francis Pearce separates the facts from the friction

Lighting Journal June 2014

Street lighting

The image used in the Daily Mail article


n an article dated 22 April 2014, headlined ‘Coming to a street near you – the lights that keep you awake and could make you ill’, the Daily Mail claimed that ‘in their rush to embrace the new “green” technology, Britain’s councils have ignored several serious health issues’. In bold type, it stated: ‘LED lights like this may even cause blindness.’ The full-page feature also said that ‘LED lamps, like so many other modern innovations, are an ugly and potentially harmful blot on the urban landscape.’ Although it mentions other authorities, the story leads with a resident of Chiswick, part of the London Borough of Hounslow,

Rob Gillespie of Hounslow Highways

recounting that he and his wife have had to install World War II-style blackouts to shut out the light from newly installed LED street lighting. ‘The gentle golden glow of the old lamps had been replaced by a harsh beam which, they say, makes it impossible for them to sleep,’ the Mail explains. BBC TV picked up the story and an anti-LED lighting resident posted a video on YouTube. Since January 2013, a consortium called Hounslow Highways has been running the borough’s highways service under a 25-year, £80m ‘pathfinder’ Private Finance Initiative. The consortium includes Vinci-Ringway, which carries out construction, operations and maintenance. Under the deal, Hounslow Highways has begun replacing street lamps with white LED lighting as part of a borough-wide programme of improvements covering 259 miles (432km) of roads and 458 miles (763km) of footpaths, including their street furniture and lighting. ‘There are about 16,000 units being renewed, of which about 10,000 have gone in,’ says Rob Gillespie of Hounslow Highways. ‘We have had about 40 complaints that they were too bright.’ The change is from sodium lighting to Philips’s Stela luminaires on S-class roads for cyclists and pedestrians including residential roads, pedestrian streets, parking areas, footpaths and


cycle paths. Hounslow Highways is installing Philips’s Luma on ME-class traffic routes. The new lighting is controlled and monitored under Philips’s CityTouch central management system, operated from a centre in the borough. ‘There are a large number of different head configurations in use in the borough to meet the point-for-point requirement, and achieve the most energy and carbon efficient solution, says Gillespie. ‘Philips did indeed provide Stela luminaires for the lighting upgrade taking place in the London Borough of Hounslow,’ says Philips. ‘These LED street lighting luminaires are designed for use along roads, walkways and in parks, and are fully compliant with all relevant international and British quality standards.’ However, ‘as Philips was not responsible for the final design or installation, including the positioning of the luminaires, we are not best placed to comment further on the lighting scheme.’ ‘Across 95 per cent of the borough people are happy with it,’ says Hounslow Council’s deputy leader

Hounslow Council’s deputy leader Colin Ellar

Colin Ellar. ‘We have only had about 100 complaints of which 25 or 30 said lights were too dim and about 40 that they were too bright. We are about half way through so that is out of 120,000 people from a population of a quarter of a million. Some people also said they don’t like white and want to go back to yellow.’ According to Philips, more than 120 local authorities have adopted Stela as part of their energy-saving solution across the UK, with almost 100,000 units having been installed. ‘Local authorities are under pressure to reduce energy bills and street lighting, which can account

than warm ones. Lighting Design House principal Mary RushtonBeales, who lives in the area, says that viewed from an aeroplane flying into nearby Heathrow Airport, the borough’s ‘ghostly white’ LED lighting reminded her of the Dementors in the Harry Potter movies. ‘It just seems so obvious that using such a cold colour temperature was always going to end in tears,’ she says in an online discussion. The matter of colour temperature is not restricted to Hounslow, and relates to a common issue with PFI contracts. ‘Often, the problem with PFIs is that the people running them are looking for the most efficient way of doing it

manager Michael Mould. ‘Hounslow Highways is driven by two or three criteria. One is that they want to put in a product that is cheap to run and cheap to maintain, with very little on-cost,’ says Ellar. Philips says that Stela’s service life is 100,000 hours, or 25 years, based on 4000 hours a year. ‘These LEDs are probably going to be working in 30 years’ time,’ he says and Hounslow Highways has ‘used good quality poles with a good treatment, so we don’t think we will have to replace them within 25 years. One of the drivers of the infrastructure is to make it very robust in terms of longevity.’ The criticism from lighting professionals, however, centres on issues such as colour temperature.

Mary Rushton-Beales: ghostly white effect

The fittings specified have a colour temperature of 5700K. Although parity is gradually being achieved, cooler white LEDs are still more efficient

and can quite easily come up with a solution that is within the word of the specification but not within its spirit,’ says CU Phosco chair William Marques. ‘The specifications for street lighting are not up to what they should be and that allows people using very high colour temperatures and S/P ratios to “bend the rules”. Most responsible manufacturers think that 4000K is about as high as you should go.’ He says councils should stipulate a colour temperature limit in similar contracts. ‘No one is really thinking things through when they use these PFIs with LED fixtures and streetlamps,’ says Mark Major of Speirs and Major, responsible for a series of key urban lighting masterplans and designer of an award-winning street fitting. ‘They tend to move towards cooler colour temperatures because they are more efficient, which is understandable, but they don’t think about the impact on the character of an area. Neither do they consider that there is the opportunity to

challenge prevailing standards. In other words: potentially lower light levels to compensate for the improved quality and CRI of the fixtures.’ Authorities throughout the UK have shed their lighting departments and transferred skills and knowledge to their suppliers, either by contracting out or under TUPE, the Transfer of Undertakings Protection of Employment Regulations. This can mean that they are unable to balance out contracts that overemphasise efficiency and underplay other aspects of a lighting installation. For example, Rushton-Beales says the choice of colour temperature in Hounslow appears to have overlooked the psychological effects of colour temperature described by the Kruithof curve, a rule of thumb that says that ‘pleasing’ colour temperatures are lower at lower levels of illuminance. The Final Business Case for the Hounlsow PFI, published in 2012, says: ‘From the inception of the project it has been apparent that up to 200 existing LBH staff and external contract staff would be eligible for TUPE transfer by being wholly or mainly engaged in areas of work becoming the responsibility of VinciRingway.’ Ellar puts the final number lost from road maintenance, road design and lighting at 20 or 30. ‘Most of the residents’ [reported] criticism of the lighting could have been avoided through better lighting design and assessment rather than a different choice of lighting technology,’ says Mould. ‘Any white light source will have raised the same concerns as

are because of change rather than being product specific. Complaints happened with the change from lowpressure sodium to high-pressure sodium. The mistake a lot of residents make is to look at the light source which gives the impression of glare.’ Of greater concern are the Daily Mail’s claims that LED street lighting is a public health risk. ‘Unqualified statements of “the dangers of LED” are potentially damaging to an entire industry of which the author seems to have no proper understanding,’ maintains Mould. ‘It is true that lights that keep you awake can make you ill, unless you install blackout curtains,’ says Rushton-Beales. ‘Even a little bit of white light, especially light high in the blue end of the spectrum, in the wrong phase of our bodies’ circadian rhythms, is more likely to disrupt our body clocks than warm white or amber light. But it is false to state that LED lights “like this may even cause blindness”. Only if you look right into the light for hours.’ ‘When a white light solution replaces traditional discharge street lighting it does usually mean adding more blue,’ says Philips. ‘But it is a tiny fraction of the content in natural daylight, and does not have any detrimental effect on people. Research actually shows that light

levels need to be in excess of 30 lux for any melatonin shift to take place and typical street lighting levels are 10 lux, less than light levels normally found in the home.’ Light trespass, on the other hand, ‘should always be of paramount concern to any considerate lighting design professional and is not a problem specific to LED lighting. Look in any residential street and you will see obtrusive light shields adorning many columns and lanterns in order to prevent unwanted light spill into private property,’ says Mould. ‘This is no different with LED and in fact, due to the more precise control, unwanted light spill should be easier to avoid through good design practice.’ ‘The street lamp that was reported in the press is compliant with ILP guidance on glare and intrusive lighting but it is at the top end of the compliance zone,’ says Ellar. ‘There were short columns which had to be reused in order to meet the output specification. It had to have a higher output luminaire on top of it and because it’s a low column with a wide road with a rake on it, it looks bright.’ A dimming trial was carried out in the Chiswick street in question, according to Gillespie. ‘The outcome there is that the luminaire has been changed for a smaller one and considerably dimmed but the actual


lighting specification for the street is not now in compliance. You can’t dim substantially and maintain compliance across the whole road’s width and length. ‘All the lanterns apart from the one described are running at their optimum levels and there hasn’t been any dimming per se across the borough,’ he continues. ‘The council is looking at whether we can do a new lighting design with new columns where we would expect to go up in height to get better cut-off and less potential for intrusion.’ However, Alistair Scott of Designs for Lighting and chair of BSI panel EL/001/02 Road Lighting, picks up on Gillespie’s point about dimming and compliance. ‘Dimming will not change the uniformity. It will allow you to change lighting class as the conditions change – for example, as traffic or pedestrian flow reduces. ‘Another aspect which may have an impact is if the mounting height is increased to provide better uniformity,’ continues Scott. ‘This will affect the residents who have the column close by.’ Lack of public consultation has

Alistair Scott: dimming won’t change uniformity

been another issue. ‘One objection we have had is that “we weren’t consulted” and that’s quite right,’ says Ellar. ‘Even councillors weren’t consulted. We did not make the choice to use LED lights and it was only when they went up that we were aware they even existed. But if someone comes along and says “do you want millions of pounds worth of infrastructure?” you say “yes”. ‘I was looking for all kinds of problems but why would you expect people not to like new lights?’

Lanterns project

Part-night whole story The aim of the Lanterns project is to shine a light on the facts behind accident and crime figures attributed to switch-off by the media. Dr Chloe Perkins outlines the aims and explains why it is crucial for all local authorities to take part

‘This is exactly the type of research that local authorities and the street lighting industry need to inform their policies and their strategies’ – David White, Royal Borough of Kingston Lighting Journal June 2014

Lanterns project 15 ‘Big rise in deaths on streets with lights turned off’, declared the Times on 21 April 2014. Its transport correspondent reported that: ‘Road casualties in areas where street lights have been turned off have risen by 20 per cent in four years, raising fears that costcutting and carbon emissions targets are claiming lives.’ The story was also carried by the Express, Sun and Daily Mail, who explained that ‘... in 2011-12, 324 more people were killed or seriously injured in crashes at night in roads where street lights were switched off than the previous year… deaths rose by 39 per cent and serious injuries rose by 27 per cent.’ Are these results true? The research was conducted by the Times Data Team which analysed data collected by the police on all road casualties between 2009 and 2012. For each casualty, the police record information on where the collision happened, including whether it was dark and whether street lights were lit or not. Their analysis showed increases from 18 to 25 fatalities and 177 to 225 serious injuries between 2009/10 and 2011/12 at night on roads where street lights were unlit. Care is needed when interpreting these changes in casualties over time. For example, the increases may mean that roads where street lights are not lit at night have indeed become more dangerous since 2009. Or it may mean that there are now more roads where street lights are not lit at night than there were in 2009. Simply comparing numbers of casualties over time does not tell us whether the roads are becoming any less safe than before. An analysis should take into account any changes over time in the numbers of casualties on all roads, whether street lights are lit or not. And ideally, the analysis would also control for other factors associated with road safety, such as speed limits, junctions and parked cars. This is what the Lanterns project aims to do. Why the Lanterns project is needed In the current economic climate many local authorities are facing budget cuts and difficult decisions about where savings might be made by reducing levels of public services. Street light provision is one such service. But to take decisions on reducing provision of night-time street lighting while maintaining public safety requires

reliable evidence to be available to local authorities on any impacts on road safety it may have, as well as on other concerns such as crime and fear of crime. The Lanterns project aims to answer reliably whether reducing night-time street lighting levels for environmental and energy reasons has any impact on road traffic injuries and crime. For this it will use the specific locations of street lighting columns (X-Y coordinates), the nature of any changes to lighting (for example, part-night lighting and dimming) and the dates the changes were implemented. It will then compare any increase or decrease in casualties (and crimes) on the roads when lighting is reduced, with any increase or decrease in casualties (and crimes) on similar roads where the street lighting has remained unchanged.

Lanterns appeal The Lanterns project, in partnership with the ILP, has been inviting all local authorities in England and Wales to participate. Since our last Lighting Journal news feature in July 2013, we have had a fantastic response, and by April 2014 there were 69 local authorities participating; each had provided or agreed to provide its street lighting data. We have appreciated the expertise and enthusiasm of all those local authority representatives who have responded to our call so far. If you are responsible for street lighting and haven’t yet been in touch, we would like your local authority represented in our research. Our shared aim is to obtain the best available national evidence on the association between lighting levels, road safety and crime. We all want the most accurate results, but their quality depends on the number of local

you to give us your feedback on the results and their relevance to policy makers and lighting professionals before the report is finalised.

How to take part We need information from all local authorities on implemented street lighting adaptation schemes. The data required are simple and include: XY coordinates of columns, nature of changes to lighting (for instance, part-night lighting) and the dates of implementation. Please contact us by email or telephone and we can provide you with our data request document, or talk through the requirements. If you are interested, but currently unable to collate this data, please let us know so we can explore additional routes of participation for your local authority.

A report on the preliminary results of the Lanterns project will appear in the September issue of Lighting Journal and full results in early 2015.

Results These will be published in December 2014. To guarantee inclusion in this national evaluation, data need to be received soon. If you can provide this by August 2014 you will be invited to attend our stakeholder meeting on 23 September 2014, and be among the first to hear about, and discuss, the results. This will be an opportunity for

Comments on The Times article and Lanterns project ‘The UK needs to understand if public spending cuts are in fact increasing road deaths and serious injuries or if other reasons are delivering misleading headlines...Statistics can be a powerful tool in aiding experts identify trends and patterns. However, the same information in the hands of laypeople can result in ill-considered, knee-jerk reactions and potential unnecessary anxiety.’ – Dave Franks Westminster City Council

‘We support the Lanterns project as an independent analysis that will support our own findings – that part-night lighting applied correctly can reduce this service’s environmental impact without compromising road safety or crime. Involvement in the project has been easy and the Lanterns team has been very open about its work and listening to our concerns.’  – Alison Dray Wokingham Borough Council

‘Improving road safety and reducing the number of people killed or injured on our roads is a key priority for councils. Police and communities are always consulted before street lighting is reduced or dimmed and if councils were presented with evidence it was causing a public safety risk they would act. ‘However, this data [from the Times Data Team] fails to provide that evidence and it is completely misleading to suggest it tells us anything about the cause of accidents. Detailed academic research into a link between street lighting and road accidents is underway which will help councils take decisions about where or when to turn out lights. We will be looking closely at the results and what they mean for improving road safety when the study is published later this year.’ – Local Government Association spokesperson

lluminate is a research project part funded by the European Commission under the competitiveness and innovation framework programme. Launched in 2012, the main goal is to demonstrate the benefits of solid state lighting to the general public. Such benefits include a reduction in energy consumption, a reduction in total cost of ownership, and also the possibility to improve the lighting quality and provide a new level of interactivity for the users of a venue. The application of the Illuminate projects is primarily urban areas, technical life support spaces, museums, aquariums and a zoo. The project involves building up a network of exposition buildings and cities in Europe in order to apply and assess the benefits of SSL technology in a wide range of scenarios and promote replication beyond the project boundary. The project consortium is driven by the end users (building operators and city municipalities) and includes a pool of experts covering all the aspects related to the solid state value chain.

• Softeco Sismat • Philips • Cenergia • Federation Europeenne des Agences Regionales de l’Energie et de l’Environnement • Enel Sole • Arup Local consultants, not working within the consortium, were appointed for the detailed design of the lighting installations and the lighting technology used in the project was provided according to the specific pilot tendering framework. The project activities have been organised in four main phases: • Assessment of existing condition • Briefing and concept design • Detailed design and installation of solid state lighting solutions • Assessment of completed projects The preliminary phase of the project, the assessment of the existing baseline condition, has been functional to create specific briefing documentation and the concept design. The data collected has been used to identify areas for possible improvements and areas where the existing schemes were valuable. After the installations have been designed and the work completed, photometrical, electrical and financial indicators have been used to compare the before and after condition of each site. User interviews and user questionnaires have been collected to measure the success of the installation and to engage a wider public. The project has been running for the past 18 months and will be completed this summer.

Standards An eclectic selection of sites, in different geographical locations and with different existing conditions but similar functions, is the subject of the Illuminate experiment. It is not reasonable to expect that a single standard will be appropriate for all the sites, because the conditions and requirements are variable from one location to another. Imagine a bespoke tailored suit and a mass-produced one. The massproduced suit will never fit perfectly. And in some cases it will not fit at all. It is the same with standards. The guidance provided by standards tends to reduce differences and directs designs to an ideal condition – a mass-produced design that reasonably fits all cases. But as the project scenarios are different, the differences should be retained, and in some cases enhanced, as it is part of the character of a given site. And difference may be actually beneficial to the end users. Therefore, given the involvement of the end users within the Illuminate project, it was possible to depart from the basic guidance and produce project-specific briefs that would be based on particular data. The seven sites have been measured and analysed by means of several indicators: luminance maps, illuminance, colour temperature readings, photographs, spectral measurements, glare measurements, visitor feedback and operator feedback. All this information has been scrutinised for problems and for areas where the existing conditions were successful. This work allowed the identification of areas where solid state technology could make the strongest impact and where differences would not be beneficial. Minimising unnecessary differences goes back to the concept

Architectural lighting 19

of ataraxia (a Greek term meaning free from emotional disturbance and anxiety) and the fact that if something is unnoticeable, most of the users will be satisfied. On the other hand, if a technology offers a strong benefit in a particular application then this should be recognised and exploited. The briefing documents, including an extensive set of parameters and design criteria, have been provided to local consultants as the basis of the design. These documents included requirements for illuminance, colour temperature, colour rendering, uniformity and luminance distribution. They also included a concept design encapsulating all the requirements of the end users, such as maintenance, durability, flexibility, and so on. Luminance as a design tool The second argument that this article discusses is how luminance could be used as an important element within the brief and design of a project. Luminance is the objective measure of the subjective sensation of brightness: it combines light and the property of surfaces into a single indicator. For example, luminance explains why a room painted in black looks dark, even with a high illuminance on the floor and walls. Considering only illuminance is one of the most obvious and overlooked errors that occurs on a day-to-day basis in the lighting profession. This is because the evaluation of luminance is position-

dependent and thus requires the use of 3D simulation software. It is not easy to identify the observer locations and most of the software used in the calculations does not consider accurately the surface properties. However, with the recent development of computer software, it is possible to measure existing luminance distribution and surface properties with a digital camera. With ray tracing software, for example Radiance, it is also possible to recreate luminance maps of the virtual model to check a particular design proposal. We believe, at this stage, luminance-based design should be a strong revolution in our work. In fact, most experienced designers already use rules of thumb based on luminance ratios, most have an idea of the luminance range of a particular type of landscape and most embed this knowledge in their projects. But even if we are all aware of this, there is little, if no mention of

Project examples Within the Illuminate project, the lighting in the corridors of the Klaipeda fortress is a good example of designing with luminance and darkness. It was designed considering the luminance distribution as the key element for the lighting effect. Luminance was selected based on the measurement in the existing building

The luminance of the floor is low but this better complements the effect on the vaults which are the main feature in the space. Illuminance on the floor is well below the recommended values of the standards. However, the overall effect, achieving an oneiric quality, justifies this departure. Another example where light levels are kept below the recommended

Light levels, safety and security are all determined by our culture and society. Therefore the idea of standardising these is essentially wrong luminance in the standards. We would hope that this craft and knowledge will finally be embraced by standards, and that luminance will be considered a more appropriate criterion for determining a lighting design than illuminance. Considering luminance in a scheme will allow the next evolutionary step, designing darkness. Designing darkness I remember the sound advice of my old colleague Massimo Bizzaro, who lit the San Marco and San Giorgio churches in Venice. He used to explain how difficult it was to accent a cupola without being obvious. It was the time of metal halide and dimming was not an option, so a lot of time was spent on site defining aimings and levels. His goal was to achieve accent with the minimum amount of light, playing with soft shadows and lack of lighting rather than strong accent.

Architectural lighting 21 tanks is the main driver. This is why illuminance requirements were not considered; instead, a luminancelimiting target was specified for floor and other surfaces, so that fish tanks would not suffer from unwanted reflections or lack of focus.

Considering only illuminance is one of the most obvious and overlooked errors that occurs on a dayto-day basis in the lighting profession countries, may give rise to some criticism in regards to safety. In fact it is common to justify increased light levels with the argument of safety and CCTV lighting requirements. However, it is important to note that CCTV requirements should be updated with the advancement in camera technology. Current technology has very good low light performance (ISO 400,000) and does not require much lighting to provide good images. Outside of the Illuminate project realm, a good example of a dark cityscape is the waterfront of Doha, where the illuminance is less than 1 lux on the pavement. This darkness allows you to appreciate the wonderful bay as a theatrical set with colourful skyscrapers and the dark sky above. There is just enough light to walk and to see people moving along the path. But the levels are much lower than the values recommended by standards. Suffice to say that there is no crime to report.

The Klaipeda fortress in Lithuania: a good example of designing with luminance and darkness

for accenting the front of the building. The initial concept considered a floodlighting installation. But after considering the surrounding environment and the existing low key lighting, it was decided to change this

Conclusions Light levels, safety and security are all determined by our culture and society. Therefore the idea of standardising these is essentially wrong. We are different and live in different geographies and environments, and we should be striving to preserve these differences instead of conforming to all the same values. Difference should be valued and our role should be focused on helping clients to understand their specific needs, and codify these with projectspecific briefs and tailored standards. And ultimately we should be designing darkness as much as light. Giulio Antonutto is an associate with Arup Lighting society/apps/projects/factsheet/ index.cfm?project_ref=297227

Joint accounts Scotland has found it pays to collaborate to fund energy efficient street lighting, says Lindsay McGregor


he spiralling cost of energy, coupled with the introduction of carbon taxes, is leading to Scotland’s public bodies to think differently and work more collaboratively to help achieve greater savings. In particular, this new partnership approach is achieving a step-change in investment in energy efficient lighting across Scotland. In many cases, energy consumed for street lighting can account for up to 25 per cent of local authorities’ electricity spend and 25 per cent of electricity-related carbon emissions. Rapid changes in technology means that a whole raft of infrastructure, which was previously unaffordable, now has the potential to make a massive contribution to its own costs, if not pay for itself. The Scottish Futures Trust (SFT) – an organisation established in 2009 to deliver increased value-for-money across public sector infrastructure – working in collaboration with East Dunbartonshire and West Dunbartonshire Councils, developed two pilot business cases to explore ‘spend to save’ financing models to fund energy efficient street lighting within the two local authorities. The aim was to develop structures that could be rolled out across other local authorities in Scotland. The business cases examined relevant technical options, possibilities for leveraging in European funding and the various commercial models that may be applicable to local authority spend-to-save initiatives, as well as identifying the potential savings both in financial and carbon terms. Based on this work, both councils have incorporated investment in LED lighting as part of their future capital investment plans. As a direct result of this work, last year SFT and SCOTS (Society

Lighting Journal June 2014

of Chief Officers of Transportation in Scotland) published a street lighting toolkit that enabled all local authorities to test the viability of LED street lighting across their estates. Street lighting is now a major priority in Scotland – an SFT study1 indicated that an investment of £300m in LED lighting would deliver up to £900m of avoided costs over a 20year period – a payback of six years pre-financing. To encourage investment in energy efficient street lighting, a steering group was established to identify and coordinate the support required by local authorities to take projects forward. The steering group has representatives from local authorities, SFT, Resource Efficient Scotland (RES), SCOTS, Scotland Excel (centre of procurement expertise for Scotland’s local government sector) and CoSLA (Convention of Scottish Local Authorities). The strength of the spend-tosave case means that the majority of local authorities will take forward street lighting schemes over the next two years assisted in part by the availability of Salix finance (0 per cent interest rate loans) and £2m enabling funding from the Scottish Government. Unlike other spend-to-save schemes, where there is a delay between investment and savings being achieved, savings immediately start when the energy efficient lighting is installed. To ease delivery of these street lighting projects, Scotland Excel has procured a Street Lighting Materials Framework which includes a Lot and specification for LED street lighting. Further advice and support to local authorities is available from SFT to assess the potential financial and carbon savings that could be captured from a programme of energy efficiency

works to street lighting, on the financial, commercial and procurement options for delivery, and to develop business cases. In addition RES gives local authorities technical advice and support for street lighting condition audits and business case development, and a street lighting adviser has been appointed by SFT to provide local authorities with additional technical assistance. As well as achieving substantial financial and carbon savings, accelerated investment in energy efficient street lighting across Scotland will boost economic development through enhanced business opportunities for the supply chain and additional jobs and training. For example, to contribute to the additional resources required to deliver investment in energy efficiency works to street lighting, eight Highway Electrical Modern Apprenticeships are being provided. In addition, SFT, RES and SCOTS are working with Scottish Enterprise to run a research and development competition to look for retrofit solutions for improving energy efficiency in street lights. The possibilities of establishing street lighting recycling business opportunities in Scotland are also being investigated. Today, little over a year since the Street Lighting Toolkit was launched, 95 per cent of all Scotland’s local authorities are now looking at their future capital investment into LED street lighting. uk/files/publications/LED_Street_ Lighting_Assessment_Scotland.pdf 1

Dundee City Council, and Perth and Kinross Council have installed new street lighting areas in residential and urban areas across Tayside. The Street Lighting Partnership, an integrated organisation comprising Tayside Contracts, Perth and Kinross, and Dundee City councils, operates and maintains the street lighting in this area on behalf of the councils. The SLP has total responsibility for design, maintenance and any renewal programmes within the two council boundaries. A total of 519 Philips Mini Luma LED luminaires have replaced 135W Sox lanterns in Dundee on both residential bus routes and priority traffic routes, and 770 luminaires are about to be installed in Perth and Kinross. Annual energy reductions are estimated at 665,447kWh, delivering savings of £73,199 a year. This represents an energy saving of 71 per cent and a carbon reduction of 6728 tonnes of CO2 over the 20-year life of the luminaires. The project was realised as a result of funding secured from Salix, with a payback period of under eight years. ‘In these austere times of having to make hard financial decisions, the availability of Salix funding at 0 per cent interest has allowed the council to tap into an alternative spend to save funding to carry out a project which would otherwise not have gone ahead,’ says Lindsay McGregor.

Stem programme

Passing the torch

Graham Festenstein briefly explains the Stemnet programme and, together with Jonathan Green and Mark Cooper, gives a flavour of what it’s like to pass on knowledge to young children


temnet (the Science, Technology, Engineering and Mathematics Network) is an organisation set up to promote Stem subjects in schools and with young people in general. To do this it has enlisted more than 26,000 Stem ambassadors, volunteers involved professionally within these disciplines, to provide a resource for schools and educational events, raising awareness of how valuable, interesting and rewarding these subjects and careers can be. Recently a number of ILP members have signed up and here three of us share our experiences in the classroom. The ILP is keen to promote the Stemnet programme and is looking at ways to support fellow professionals who want to become involved. Hopefully these examples will inspire others to take part.

Lighting Journal June 2014

Graham Festenstein Graham Festenstein Lighting Design

I have always been interested in promoting lighting through education but until now this has been limited to undergraduate students and adults. The idea of becoming a Stem ambassador, however, really appealed to me, as my own experience at school left a lot to be desired in terms of understanding the opportunities and careers in design, architecture, engineering and other technical subjects. This was obviously some time ago, but as my daughter has progressed through the school system it has become clear that although there has been some progress, things have not really changed as much as I would have hoped. The root cause of this, in my opinion, is not a lack of desire among teachers to promote these sort of careers, but in fact a lack of

Stem programme 27 understanding among the teachers themselves, of the varied and specialist careers that studying Stem subjects can open up for young people. In this way the Stem ambassador programme not only supports teachers, but also educates them in the more specialist or seemingly obscure disciplines that many of us inhabit. Recently I took part in an event at the Observatory Science Centre in Herstmonceux, East Sussex. This was aimed at KS3 students, of which around 250 attended throughout the day. I must admit to being somewhat nervous before the event as working with children, as I previously mentioned, was not something I had much experience with. At the beginning of the session I did find it difficult, and consequently had to adjust my method of delivery significantly, to adapt to what I found to be very attentive and interested young people, many of whom were much more engaged than I had imagined they would be, and who asked many intelligent and pertinent questions. All in all I found the day extremely rewarding and I am sure many of the children went away with knowledge that otherwise they would have been unlikely to have gained elsewhere. The range of other activities was extremely interesting too; from interactive virtual reality (demonstrating the vision of a bee as it searched for flowers), a ‘banana piano’ (with a keyboard of real bananas) through to softwarecontrolled robot Lego cars. The activity I chose invoved a range of luminaires from tiny 1W LEDs through to 3000lm light engines, fibre optics and RGB. I also took a range of lamps showing the development of light sources, from the tungsten lamp, through to LED, and the diversity of sources in between. Along with these I had various reflectors, lenses, filters, ribbed glass, shot-blasted glass and dichroics, all of which the children could play and experiment with (we were lucky with this event in that it was not in a school and could consequently be a hands-on activity). The idea behind all of this was to demonstrate the amazing diversity of skills that go into lighting; from the physicists and chemists who develop the light sources and filters, the engineers and product designers who develop the lamps themselves and then the luminaires, through to the designers who put these into use

on buildings, roads and architectural spaces. Along the way I could touch on the electrical engineers, architects and other professionals involved in the delivery of construction projects, and even the biologists who look at the impact of lighting on our physiology and psychology. Using scheme photographs and images, my final aim was to show how science and technology contributes to the creativity of design in architecture and urban design, something that is far from the day-to-day experience of the average teenager.

When I was a child at school learning about right-angled triangles, the Pythagoras theory and trigonometry, I asked myself, ‘When am I ever going to use this in my life?’ This same question seems to be the mantra of all young students and as a Stem ambassador I get the chance to show how it is used in lighting to calculate the point illuminance or intensity values.

I have given practical presentations of the necessity for trigonometry in lighting at various schools in Nottinghamshire to pupils ranging from 13-16 years. Each time I mention the ‘T’ word I smile inwardly as an audible groan escapes from the mouths of 25 young students who would rather do anything else than sit through an hour of opposites, adjacents and hypotenuses. However, once the lesson unfolds and the use of trigonometry becomes clearer, understanding takes over. Where there were once lost students trying to figure out which element of Sohcahtoa to use, now in their place are attentive students with light bulbs above their heads. This in itself has given me pride, that I have helped to provide a better understanding of probably one of the most dreaded subjects in school. In addition to undertaking these local classes, I had the honour of being a careers specialist at this year’s Big Bang Show at the NEC, Birmingham. This involved a gruelling but rewarding three days of being interviewed by young scientists, engineers and mathematicians aged between eight and 16. Once the obvious question of ‘How much do you get paid?’ was out of the way, I was both surprised and impressed to find that there were some very interesting questions asked about lighting and how it all worked. Obviously it’s a mammoth subject to cover within the allotted five minutes each group was given, but I was happy to address any issues the young engineers had, and thoroughly enjoyed the short but very mature conversations I had with each one. A couple of times I even had the chance to talk about the importance

of professional registration and to tell them that, even at my age, I am still learning. All in all it was a thoroughly enjoyable experience and I think I learned as much as my young visitors. During my time giving presentations and taking part in events, I have come to realise that being a Stem ambassador is much more than just contributing towards my annual CPD requirement. It’s about encouraging the next generation to take our place. To teach and nurture budding engineers. But, above all, to instill confidence and show that we are the professionals that they could be – the future us. Mark Cooper National sales manager public realm, iGuzzini Senior vice president, ILP I have always been interested in

education and training; I have a passion for lighting and have never understood why some people insist on trying to make this industry a mystery. I like to talk to people about my career and often find that most people don’t even know that such things as a lighting engineer or lighting designer exist, or have any idea as to what we do. Furthermore they certainly don’t understand that this job is an amazing mix of science, technology, engineering, mathematics and art. When my youngest daughter’s school sent home details of science week, I approached the science teacher and asked her if I could help. We sat down after I explained what I did for a living and she was so grateful for the help. I had a few ideas as what we could do for a group of seven to

Lighting Journal June 2014

nine-year-olds, but quickly my idea of doing something in a classroom for one class mushroomed into a whole day of teaching for the whole year group – not only that but I was to kick off their science week. We spoke about the format for the day, how the lessons and workshops we discussed could be tied into the rest of their events for the week, and also the curriculum. Once I had worked out what we could do during the day, and what equipment I needed to demonstrate things such as colour mixing, creating rainbows and a ‘light show’ at the end of the day, I went and spoke to my company to beg borrow and steal some fittings. They were very good in allowing me to use some of our own demonstration materials, for colour temperature, for instance, as well as lots of fittings, lamps and LED samples. I put together three presentations and some basic lesson plans. These comprised an initial introduction to the whole year group, covering what a lighting engineer does, some of the projects I have been involved in and what we were to learn through the day. The second was a workshop, and the final presentation of the day was in front of the whole school, summing up the day and demonstrating, with the help of the children, a light show in the school hall. The whole day was very interactive, with lots of hands-on experience and use of multimedia, ensuring the children had a chance to learn for themselves – asking lots of questions, working out for themselves what was happening and then going off to examine further materials within the classrooms. I felt that the day went well, and the feedback from the school has been great, but the acid test has been that when I have taken my daughter back into school, the children have all been talking to me, asking more questions and telling me how much they enjoyed their day. I even got a special card made by all of the children, with comments in it, something I will hold on to and value. The other thing I will retain is the sense of achievement I got, and the enjoyment and encouragement I received from seeing young children inspired and enthusiastic about science and maths. If you ever get the chance to undertake this type of teaching, do it, you will receive as much as you give.

During my year as president, one of my goals will be to create a series of lesson plans, presentations and workshops that can be used by members throughout the UK to assist their local schools. I also want to create a process that allows us to coordinate with Stem and get more of our members joined up as ambassadors. From this, if we can just get a few more young budding engineers to think of a career in lighting, then it would have been worth the effort. But the benefits it will bring those members involved, and the boost to their enthusiasm for the industry we work in, cannot be overestimated.

Feedback from the school Dear Mark Both the children and I got so much out of your day and then we continued throughout the week, extending and investigating our learning. I know the children got a lot of inspiration from their day. A wonderful start to our science week. I have attached some photographs the children took while working out their investigation, some are very beautiful and a rather amazing one (they don’t know how they did it, they saw a rainbow in the semi-circle and tried to take a photo).

Exhibition review

Street smart In the second part of a review of Light and Building in Frankfurt, Jill Entwistle looks at exterior fittings, plus controls and components

EXTERIOR Neri Hydra The Hydra system has a remote phosphor LED source, with the phosphorous glass appearing white in the off state. Output is 3000lm or 4000lm, colour temperatures 3000K or 4000K, and distribution is symmetrical. The columns are steel, with diecast aluminium lantern. Standard finish is black. The upper frame can be opened for access to the gear compartment and the light fixture remains sealed for installation. The light fixture has an IP43 rating and the optical compartment is IP66. Control includes 1-10V, Dali, and Neri Variable Lighting (NVL), which gives six hours automatic flux reduction (standard solution). The fitting also includes a Wi-Fi system. Selux Arca

Arca has an integrated universal adapter that enables flexible use as a surfacemounted, wallmounted or upswept pole luminaire. The luminaire head can be adjusted plus or minus 20 degrees in fivedegree increments on both mounting variants. With an asymmetrical light distribution, the Arca is designed for residential or service roads, paths, parks or company grounds, and comes with a range of system powers depending on the application. The luminaire has Selux-developed reflectors to ensure high luminous efficiency from the LEDs – two pairs of tapered

Lighting Journal June 2014

reflectors with triple curves at the sides enable uniform lighting with fewer luminaires. Colour temperature is 3000K or 4500K and it has a Dali or 1-10V interface. The housing can be opened without the use of tools using an elbow lever lock. Simes Shape Winner of a Red Dot award this year, Shape is a neat fitting (150mm high, 100mm deep and 40mm high) that creates uniform light to the outer edge of windows. Using only one 4.5W LED (4000K) output is 300lm. The IP65 fitting has a radial lens of 10 x 170 degrees, and its angle can be adjusted according to the slope of the window reveal. The housing is diecast aluminium (aluminium grey or white) with a polycarbonate diffuser. Fagerhult Vialume 1 Developed in conjunction with ÅF Lighting, Vialume 1 is a post-top, S-class LED luminaire. It features the company’s Advanced Glare Control lenses, whereby light is distributed through large lenses that sit close together to form a single luminous cluster. This also illuminates the inside of the light opening so that it is visible from a distance. The fixture can be tilted steplessly and mounted on a 60mm-diameter pole top or 42-48mm-diameter arm.

Exhibition review 31 WE-EF LED post-top range WE-EF has added three new post-top luminaire series to its LED amenity range. The ZFT400 fittings (one of which is pictured left) feature the recently developed FT 360 degree LED PMMA lens with a low glare, symmetric light distribution. The RMT300 and CFT500 series use the company’s OLC (One LED Concept) lens technology with a multi-layer principle. The ring-shaped luminaire body of the new CFT500 led to the development of new semi-circular LED boards. The RMT300 post-top luminaires can be fitted with three different LED lens systems to suit specific requirements: S65 or S70 lenses for asymmetric distribution and R65 lenses for forward throw distribution. An additional optical component developed by WE-EF is designed to increase efficiency further. Using RFC (Reflection Free Contour) technology, a conventional flat luminaire lens is replaced by a clear, UV-stabilised acrylic panel with a contoured surface that matches the shape of the lenses. This results in the proportion of internal reflection being reduced to an absolute minimum. iGuzzini Wow The Wow LED street lighting system comes in a wide variety of permutations, with heights ranging from 4m to 12m and lanterns available in three sizes (307mm x 620mm, 415mm x 758mm and 505mm x 807mm). With both road and asymmetric Opti Smart optics (which are adjustable and replaceable), the series includes single, double and triple pole-top options, wall-mounted version, and shaped poles for a more decorative effect. Colour temperatures are 3000K and 4000K, and the driver allows the use of three fixed profiles and one variable profile for different lumen levels and different powers. Thorn Lighting Urba Designed by architect Jean-Michel Wilmotte, Urba is one of two new LED road lanterns introduced by Thorn. In two sizes and with output up to 15,000lm, it comes with a range of mounting and optical choices, including a dedicated comfort optic. It will be available this autumn.

Sapa Pole products Soluxio Soluxio works exclusively through solar power, storing generated energy in built-in battery packs housed within the pole. It can be customised, making it compatible with a broad range of luminaires for different applications. Using integrated solar modules with high-yield solar cells, the pole automatically adjusts to deliver the desired amount of energy, including in cloudy conditions, low yield, or indirect sunlight. As well as lighting, the stored energy can be used for other applications, such as a surveillance camera, weather station or a GPS system. Batteries have a lifespan of up to 10 years. The product is the result of the collaboration between Dutch company Sapa and solarpower specialist FlexSol Solutions.

CONTROLS, DRIVERS AND SOURCES Mackwell SSD Mackwell has spent three years on the R&D for SSD technology which integrates the driver and support components in one miniaturised package measuring just 7mm square. The driver is completely solid state, with no life-limiting electrolytic components, which significantly reduces the size and improves durability. The technology uses LED AC direct technology which removes the need for complicated circuits, inductors or capacitors used in SMPS or AC/DC LED drivers. As the ASIC (application-specific integrated circuit) chip sits on the LED engine, mains power can be supplied direct, without the need for a standard LED driver. Mackwell will offer a series of standard form sized SSD LED engines and also help with customised solutions. Philips CityTouch light wave Philips has introduced new features for its web-based street lighting management system. CityTouch light wave is a new remote lighting management system that includes plug-andplay connected outdoor lighting fixtures. The system can be implemented quickly and cheaply, says Philips, using LED outdoor fixtures that feature built-in mobile connectivity to

Exhibition review and interface with other building systems such as heating, ventilation and IT services. A single system thus shows real time and historical views of how a building is being used so that adjustments can be made accordingly by facilities managers. The fixtures, with wireless communications devices, form an indoor positioning grid that can also support a range of location-based services, such as wayfinding or locating the nearest empty meeting room.

the CMS. This avoids the need to deploy local RF networks, reducing installation costs. Once the fixture is plugged in, a light point automatically appears on the CityTouch map at its location and with its main technical parameters already integrated into the system. The remote lighting management system allows central control of all lights in an area, either individually or as a group. The software also provides the current lighting status, auto-notifications of faults and accurate information on energy usage of each street light. Philips has also launched CityTouch light point, an asset management system that enables cities to access information about the street lighting network and receive real-time updates about lighting maintenance requirements. Among other features, it provides map-based data visualisations of a city’s lighting infrastructure, so that budgets for street lighting upgrades can be allocated to the appropriate areas. Lutron EcoSystem 5-Series

Lutron has extended its EcoSystem 5-Series LED driver range. It now includes a 50W LED driver that dims down to five per cent and is designed for linear, pendant and recessed 600mm x 600mm fixtures, cove lighting and LED strips. Also added is a 25W LED driver that dims to one per cent. Philips Lighting Ethernet System Using Power-over-Ethernet (PoE) to connect LED office lighting fixtures to a building’s IT network, the lighting system acts as an information pathway, enabling workers to control and access other building services using their smartphones. PoE-enabled fixtures could also provide cost savings on lighting installation as they receive both data and power over a single Ethernet connection, obviating the need for electrical wiring and reducing installation costs by up to 50 per cent, says Philips. Light fixtures equipped with sensors can also capture anonymous data on room occupancy, temperature and humidity. They connect to the IT network

Osram LED Module 540 Siteco Mushroom Luminaire LED, Lantern LED and City Light LED luminaires have been equipped with the new LED Module 540. The company’s conventional town and park luminaires can also be upgraded using the module. The 540 is designed to be low glare with an extended luminous surface that also creates a decorative effect. Sylvania Relumina It’s a retrofit but it’s not LED. The Relumina CMH lamp is designed as a replacement for mercury vapour lamps, which will be banned by ErP legislation in April next year. According to Havells Sylvania it’s the first direct retrofit lamp using CMH technology on the European market that can be fitted into existing luminaires without needing to change the control gear. Available in 55W, 85W and 170W versions to replace 80W, 125W and 250W mercury vapour lamps respectively, Relumina has a colour temperature of 3000K (CRI 84) and a luminous efficacy of up to 88lm/w. Average lifetime is 18,000 hours, around four and half years, and the payback should be within 4000-6000 hours of operation. Bridgelux Outdoor Lighting Module (OLM) Bridgelux has launched a new line of LED sub-systems that integrate optics (asymmetrical and symmetrical), environmental protection (IP66) and the LED source for roadways, underground car parks, and other outdoor and industrial applications. OLM can reduce the manufacturing cost of outdoor solid state lighting fixtures by 10 to 20 per cent, according to the company. Initially six OLM subsystems will be available, ranging in power from 18W to 40W, and with estimated lifetimes of 50,000 to 100,000  hours.




TUESDAY 24TH JUNE 2014 PROSPERO HOUSE | LONDON The surveyor and ILP’s annual lighting conference is changing this year. Building on the technical sessions and case studies in the street lighting sector, this year’s conference programme will be extended to include community lighting, reflecting the changing roles and responsibilities of lighting engineers in the UK at councils and private sector companies. How can we make community lighting more efficient and effective and what is the latest technology councils should be implementing? Brought to you by

BS EN 12464-2 Light and lighting – Lighting of workplaces, Part 2: Outdoor workplaces was first published in 2007 and earlier this year a revised version of the standard was published. This latest revision is really just a maintenance operation and there is little by way of substantive change, but there are a number of minor changes to improve clarity and some detail changes to the schedule. The first of the clarifications is in the scope, which now makes it clear that the standard does not cover emergency lighting and that you should refer to BS EN 1838 and BS EN 13032-3 for information on that particular topic. The next major difference is that the standard does not contain any definitions of the terms used in the documents – this is because all light and lighting definitions are now given in BS EN 12665. There is also some clarification in section 4.4.3, which covers the illumination of areas surrounding the task area. In the old version of the standard there were no rules about what constituted the surrounding area. In the revised standard, however, it now states that: ‘the surrounding area should be a band with a width of at least 2m around the task area within the visual field’. The area where there has been most change is in the area of energy

Lighting Journal June 2014

use and sustainability. In the old standard there were about four lines on this topic – basically it said little more than while providing the lighting needed for a given job, specifers should not waste energy and think about sustainability. In the new edition the section is much longer and there is a discussion of the use of lighting controls to respond to daylight and the absence of people in the area. The section goes on to talk about environmental life cycles, maintenance, reuse and recycling. In the schedule there are just a few changes: • In the general areas table there is a new activity: cleaning and servicing. • In the airports table the illuminance requirement for terminal aprons and loading areas has been reduced from 50 to 20 lux but the uniformity requirement has risen from 0.2 to 0.25. • In the railways and tramways table there is now a new area: ‘open platforms, very small number of passengers, for example, train stops’. In addition, the area ‘open platforms, rural and local trains, small number of passengers’ in the old standard has very subtly changed and been replaced with ‘open platforms, small number of passengers, for example, rural and local trains’.

Peter Raynham analyses the new version of the outdoor workplace lighting standard

There has also been a reduction in the required illuminance from 15 to 10 lux. The old annex A of the standard that gave lighting requirements based on the level of risk has been deleted. In the new version, annex A has become a list of nation deviations to the standard – so-called ‘A deviations’ caused when national law contradicts a provision of the standard. There are three such deviations listed, each impacting on a particular clause of

The area where there has been most change is in the area of energy use and sustainability the standard when used in Germany, Slovakia or Hungary. In summary, the recent revision of this standard has done little to change the provisions of the document, and the changes are mostly about improving clarity and ease of use of the document rather than anything more fundamental. etail/?pid=000000000030281364

Clear-sighted MIT researchers have demonstrated a new approach to creating transparent displays


number of technologies have been developed for transparent displays, but all have limitations, according to MIT, which reckons it has a better solution, at least for certain types of applications. Many current systems use a mirror or beam-splitter that projects an image directly into viewers’ eyes. This gives the illusion that the display is hovering in space somewhere in front of them. The disadvantage is that they are extremely limited in their angle of view – your eyes must be in exactly the

Lighting Journal June 2014

right position to see the image at all. Other approaches rely on electronics that have been integrated into the glass: OLEDs for the display and transparent electronics to control them. The drawback here is that the systems are complex and expensive, and their transparency is limited. MIT professors Marin Soljačić and John Joannopoulos, graduate student Chia Wei Hsu, and four other researchers say that their approach resolves these issues, offering ‘a wide viewing angle, simplicity of

manufacture, and potentially low cost and scalability’. Their system involves embedding nanoparticles, each about 60 nanometers, in the transparent material. These tiny particles can be tuned so that they only scatter certain wavelengths, or colours, or light, while letting all the rest pass right through. The glass stays transparent enough to see colours and shapes through it, while a single-colour display is clearly visible on the glass. Shown on the MIT website,

Future concept the demonstration uses silver nanoparticles — commercially available and used for the initial testing because they could be applied simply and cheaply — to produce an image. At the moment this is solely in blue but the research team says that full-colour display images are possible using the same technique. Each of the three RGB colours necessary would still show only a very narrow spectral band, allowing all other hues to pass through freely. ‘The glass will look almost perfectly transparent,’ says Soljačić, ‘because most light is not of that precise wavelength’ that the nanoparticles are designed to scatter. This scattering

allows the projected image to be seen in a similar way that smoke in the air can reveal a laser beam. At this stage the demonstration just proves the idea works and there is some way to go to make it fully viable. The particles could be incorporated in a thin, inexpensive plastic coating applied to the glass, in the same way that tinting is applied to car windows. This would work with commercially available laser projectors or conventional projectors that produce the specified colour. Applications for transparent display technologies include the ability to project images on to shop windows while still allowing passersby to see


the merchandise on display inside, to provide navigation or dashboard information on windscreens for drivers or pilots, or to project videos on to a window or a pair of eyeglasses. ‘This is a very clever idea using the spectrally selective scattering properties of nanoparticles to create a transparent display,’ commented Shanhui Fan, a professor of electrical engineering at Stanford University, who was not involved in the project. ‘I think it is a beautiful demonstration.’ seeing-things-a-new-transparentdisplay-system-could-provideheads-up-data-0121

So-called heads-up displays (HUDs) have been available in cars since the late 1980s. While early versions just showed the speed on the windscreen more recent versions show full navigation data. This is reflected on the windscreen from a projection source concealed into the top of the dashboard. HUDs producing detailed graphic imagery use light sources such as LEDs and cathode rays to project the information on to a part of the windscreen that contains phosphor cells. BMW, Lexus, Honda, Cadillac, Buick and Ford all included HUD systems in their 2013 models. BMW’s HUD technology has adjustable full-colour displays that appear to hover over the tip of the hood. Among other areas, BMW is experimenting with augmented reality (AR) technology in its HUD displays to help define roadway boundaries during bad weather. These could also potentially highlight hazards, other cars and BMW Smart windscreen (above) and Toyota Fun Vii concept car (top) show emergency manoeuvres.

VPs’ column

Gaining prominence Mark Ridler, VP architectural

lighting, on recent plaudits and positive developments


t’s been a busy time since last I wrote this column. The big news I guess has been how many of our members have won awards. Kevan Shaw kicked it off at Lux with Lighting Designer of the Year Award and was praised for his ‘rare mix of design and engineering skills’. Stainton Lighting and Kevan again both picked up highly commended for their projects. Mark Major won the FX project of the year. The Lighting Design Awards were even more successful with Mark Major (again), Kevan (again), Mark Sutton Vane and Michael Grubb all winning awards or being highly commended. I too was very proud to receive the Lighting Designer of the Year Award, as well as a couple of project awards, and it was particularly gratifying for my work with the ILP being cited as a big reason behind the award. It is ample proof, if proof is needed, of the quality and breadth of our membership. The ILP has been very active in a number of events this last year. Light School was a new educational event held at the Surface Design Show, at London’s Business Design Centre, organised by Light Collective and the ILP. It consisted of a series of lectures by an amazing selection of speakers from a very wide design background. The world of lighting has a bad habit of too often talking to itself and then complaining that no one outside of lighting listens to us. This event was different in that it was squarely aimed at the non-lighting community, in particular architects and interior designers, and to tell the story of how important lighting professionals can be in creating great projects. All the speakers I talked to were very enthusiastic, as were the show organisers, and so hopefully it will be repeated next year. More of these types of events will hopefully grow the market for us all and help us grow our businesses.

Then it was Ecobuild. As well as having a speaking presence at the show, we used this as a doublelaunch opportunity. One was for Lighting Landscapes, a beautiful new guide aimed at landscape architects, planning authorities, lighting engineers, elected members of local authorities, public consultation,

The world of lighting has a bad habit of too often talking to itself. Light School was squarely aimed at the non-lighting community

architects, contractors and prospective clients, as well as lighting designers. Beautifully illustrated with project examples, it explains how to manage, implement and maintain lighting in the public realm, and the importance of the role of a lighting professional in this process. It has been widely endorsed (see the website) by landscape architects and clients such as Grosvenor Estates. Available for sale on the website, hopefully it will succeed in promoting effective public realm lighting widely. The other launch was for How to Be Brilliant, a series of talks at ACDC London Studio. These are aimed at younger designers and cover a number of topics that include how to get a job, daylighting, how to visualise and photometrics. Again, there is a line-up of great speakers covering both the art and science of light. Recruitment of new members has been very successful and we now have around 40 members from an architectural background, and I’m glad to say that many are leaders of very prominent practices. The task now is to understand better what we can do for these members and deliver it. Also we need to extend membership from practice heads to associates, seniors and other grades within those practices. I have to confess that the scale of activity and the number of members to serve is all too much for me alone, so I am currently looking for volunteers to help the ILP in its work. Thank you to those members that are getting active. Mark Major is in the process of compiling a reading list asking members for their top 10 unmissable lighting reads. When compiled this will be a free resource on the website and the ILP intends to buy and hold in its library the most popular titles. Graham Festenstein has joined the Southern Region committee and is a member of the Lighting Journal editorial board, and I recently had a great meeting with Alison Gallagher, the new architectural lighting representative on the YLP. Thank you also to Rebecca Hines for helping me with the Skills Portal. But there is much more that can and should be done for our profession. So please join in and let’s make 2014 and the years to come successful and prosperous.

What’s new Harvard

SensorNode Harvard’s SensorNode gives a presence detection facility for the LeafNut monitoring and control system. It automatically overrides any scheduled dimming profiles on the system, returning the lights to full power for a specified period of time. The device operates through a connection with an external presence detection unit. It can therefore be used as a compromise to complete switch off, allowing scheduled dimming but enabling increased light levels when required.


Inverted Shadows Available in wall, pendant (shown) and floorstanding versions, Inverted Shadows has a clear methacrylate body with a very small (16mm x 16mm) linear extruded aluminium element. This houses the LED strips and an optical unit with an elliptical beam angle. The design allows the user to rotate this element to provide different light emissions according to its position inside the body: uplight or downlight wallwasher, indirect, or direct diffused. The 35W luminaire has an output of 1820lm (52lm/W). Colour temperature is 3000K (CRI 80).


Ralite Highbay A highbay LED pendant, Ralite is available in one, two or three lamp configurations and IP ratings up to IP67. Output is up to 26,800lm, with a luminous efficacy up to 110 lm/W, and it has a CRI of 80. Made of turned aluminium, the pendant’s vertical passive cooling ribs (extruded aluminium profiles) also minimise dust and grime deposits. It can be used in conjunction with RZB’s intelligent Light Control +³ plug-and-play lighting management system.

Cooper Lighting and Safety Galaxy LED

Cooper Lighting and Safety has expanded its range of exterior fittings with the IP65 Galaxy LED floodlight. It comes in five lumen packages – from 838lm to 17,495lm – to cover a range of applications, from wallmounted area floodlighting to floor-mounted facade lighting. The 10W and 30W versions are available with an integrated PIR sensor. With a diecast aluminium body, it has a toughened glass lens and anodised aluminium reflector



Beacon Major and MInor The Beacon Major mains voltage LED spotlight is one of several additions to the Beacon range. As it runs directly from the mains it doesn’t need a driver. The fitting is available in 27W, 3000K and 26W, 4000K options. Flood or spot versions have 36-degree or 18-degree beams respectively. The Beacon Minor is also a mains voltage LED spotlight. Equivalent to a 50W LV dichroic lamp, the 13W fitting is available in 3000K, with a spot version emitting 594lm and the flood version 623lm (fixture lumens). Both fittings come in white and black to match other models in the Beacon range.

Crescent Lighting

CRE040 and CRE070 projectors Crescent has introduced a more powerful version of its CRE040 LED fibre optic projector. A new LED array driven at 1A gives an output of 2640lm, a 12 per cent increase. It also runs at 36W (previously 40W) to deliver a 10 per cent reduction in energy consumption. The white light version (3000K and 4200K) is dimmable using 1-10V and Dali, while the RGBW version comes as standard with a selection of preset colours, or can be controlled with a DMX source. The all new white light CRE070 LED fibre optic projector looks identical but is driven at 2A to give 4320lm (at 4000K). An alternative to HQI projectors, the 70W version is dimmable using 1-10V, Triac and Dali, and offers 3000K or 4000K at CRI 80 (CRI 90 and 97 options are also available). Both models have an IP54 white light only version for exterior use.

YLP column

Matter of course Kevin Dugdale reports on two CPD events and identifies a number of opportunities to attend free CPD courses offered by manufacturers

Lighting Journal June 2014

YLP column


here are a number of manufacturers who organise CPD-accredited events and they can be both useful and enlightening. Many are available through the ILP’s Skills Portal (see details below). The YLP committee approached some of the lighting industry and its own members for information on CPD courses, and would like to thank everyone who responded. NAL Passive safety specialist NAL holds demonstration days at its Worcester offices. At the most recent event there was a short presentation on the NAL product range then a number of live demonstrations on retention socket options. We were impressed with the day’s information and activities, and would recommend it to anyone who hasn’t seen a retention socket in action or is unsure of NAL products. And as street lighting designers, we are more commonly being required to specify disconnection solutions, either from

feeder pillar or disconnection chamber. One important point that I picked up on the day was that the passively safe solution from NAL works at 24V instead of 230V which, when used with a three-phase electrical solution, eliminates a potential risk of 415V to maintenance operatives if anything is wired incorrectly. Harvard Leafnut Demonstration The Harvard Leafnut Demonstration is held at the company’s Wakefield offices. It involves an outline of the Leafnut system and some of the terminology used, with a short demonstration of the options available with a live CMS solution. The presentation provides information not only of the technical details behind Leafnut but CMS in general. Following the presentation is a short factory tour. You won’t come away an expert in CMS but you will come away with an awareness of the technology and terminology. The following table gives details of other available courses. Make your


own enquiries and judgement as to whether what is offered matches your career development requirements. This is by no means an exhaustive list and any company that provides a lighting training course which would like to be included in the ILP Skills Portal can contact Rebecca Hines ( The ILP Skills Portal has consulted leaders of the leading lighting design consultancies in the UK, and is collating together resources for all members in the lighting community. Would you like to have your voice heard by the lighting community? The YLP column is dedicated to articles, information and news about YLP members. If you’ve attended an event, or would like to write an article, or share your experiences from within the lighting industry, please contact Tom Baynham:




GE Lighting

Founded in 1933, the Lighting and Electrical Institute at Nela Park, Cleveland, Ohio, was the first facility of its type in the world devoted solely to the teaching of lighting. Today, more than 4000 visitors a year come to the institute where they can experience lighting and electrical system demonstrations and simulations. Attendees are active participants in the workshops and discussions led by the institute’s staff. resources/lighting-institute/courses/


iGuzzini carries out much of its research alongside institutions such as Harvard University and MIT. It then uses this material to construct training material that explores new trends through the use of effects, projects and products. The company runs an online technical training course that allows the students to progress at their own pace. It contains text and graphic presentations on a number of modules connected with lighting and applications, and provides an assessment test at the end of each module.


NAL has launched a purpose-built demonstration site which encompasses a fully operational street scene alongside a fully ducted crash site. Weekly demonstrations are held in which attendees get to witness numerous knockdowns and physical product demonstrations, giving them a full view of how the products perform in real-life situations. Attendees also gain an insight into the requirements for passive safe designs under EN12767. The demonstration site allows attendees to view the latest innovative passively safe products from the majority of manufacturers. asp?section=static&id=0&subid=8

Thorn Lighting

Urbis Schréder

The Thorn Academy of Light is based in Spennymoor in north-east England with smaller satellite locations in Landskrona (Sweden), Les Andelys (France) and Bologna (Italy). Each facility provides comprehensive education and training for employees and customers. Visitors can experience light at work, view exhibitions and attend workshops. Eight training modules are currently provided, ranging from one day to 60 minutes. Topics include lighting design, indoor lighting control and energy saving. The key objectives of the academy are to improve knowledge of and creativity in professional lighting and design, and deliver the ideal balance between light quality and energy efficiency.

Martin Thompson, TAL manager martin.thompson@zumtobelgroup. com

Seminars are mainly aimed at lighting engineers, but they are also very useful for designers, installers and other members of the lighting industry. With the growing commercial pressures on local authorities, both purchasing professionals and energy managers are finding them to be of increasing benefit. They cover a wide range of subjects to help attendees keep their lighting knowledge up to date. They can be tailored to suit people’s work schedules, ranging from just 30 minutes to a full day’s training, Seminars can be held at Urbis’s Basingstoke head office, or its team can travel to people’s offices.
