Everybody’s talking... In this issue, we dial in on the hot topic that’s sparked numerous debates: Human Centric Lighting... At last year’s [d]arc room, we facilitated a panel discussion about

Human Centric Lighting (HCL) chaired by leading expert Asst. Prof.

Dr. Karolina Zielinska-Dabkowska. Featuring Mark Ridler, Director of Lighting at BDP; Rebecca Weir, Creative Director at Light iQ; Stephen Lisk, President of CIBSE; and Iain Carlile, President of SLL, the

debate was lively and proved that there were many more questions than answers. So much so that we have reprised the discussion in

this issue with a professional paper from Zielinska-Dabkowska and input from lighting designers about the subject, including practical examples of where HCL is used in their schemes.

HCL is often claimed to be the next development stage in the

evolution of lighting design, yet the concept seems to have been

around forever. Indeed, when we announced the HCL discussion on

Twitter, some bright spark commented that this was old news and we shouldn’t have been giving it any further thought.

Last year, according to market research company ElectroniCast,

the global consumption value of modules/devices in HCL reached $617.6 million, and is forecast to increase 38% in 2019 to $850.9

million. Unsurprisingly, the critic was someone who worked for

a manufacturer who made lighting products that claimed to have

solved the HCL conundrum, a very lucrative market. Unsurprisingly, they are wrong.

It has become increasingly obvious how complex it is to imitate

natural light, and that far more research is required to identify what is needed to apply artificial light safely. Indeed, Dr Russell Foster

who identified the eye’s third photosensitive cells whose function is unrelated to vision, recently stated: “We can’t develop humancentric lighting until we know what impact light has upon human biology across the day and night cycle.”

Lighting designers, and especially lighting suppliers, need to take note. There is a long way to go.

Talking of debate at [d]arc room, we are delighted to announce

that, this year, [d]arc room will have its very own hall at London

Design Fair during London Design Festival in September. Attracting 30,000 visitors, the event will aim to showcase 75 architectural and decorative lighting companies to the design community. Please contact us if you’d like to be involved.

Versatile light for modern work Jilly downlights for track

If office layouts repeatedly change, the new Jilly luminaires for track offer the perfect solution. Jilly intelligently combines the infrastructure of track with downlight technology. The flat housing and striking anti-dazzle louvre characterise the elegant design for standard-compliant work-

place lighting. Jilly combines the lighting technology of a highly efficient lens system with anti-dazzle louvres. Visual comfort and luminous efficacy thus both achieve a high level. This combination allows large luminaire spacing for economical lighting concepts. Jilly is simply mounted and opti-

mally aligned with the track adapter. The colour of the housing and anti-dazzle louvre can also be individually matched to the interior.

Light is the fourth dimension of architecture

Constellation of Stargazing Tea Ceremony Houses Bisei-Okayama and Awajiiland, Japan Moriyuki Ochiai Architects has created an installation of illuminated tearooms with lighting by Color Kinetics Japan in the town of Bisei, an area known as a sanctuary for stargazing. The site was chosen for its views over the surrounding dramatic landscape of hills and mountains, and its proximity to nature and the clear night sky. Named after the two rivers running through it, Bisei is translated as beautiful stars in English. The Okayama prefecture the town is located in is known for being the birthplace of Eisai, a Japanese Buddhist priest that is credited with introducing green tea to Japan. The tearoom structures are clustered like a small galaxy and function as places to meet. The open arrangement of the constructions forms a stage to host a variety of events throughout the year, both indoors and outdoors, from the Astronomy


Club and the Tea Ceremony Club, as well as a performance stage for concerts and plays. The tearoom structure was developed as a microcosm called an enclosure, and was designed as a space that visitors could perceive live changes to its natural surroundings. The polygon openings allow for the spectating of natural light, rain and the starry night. Mirrors were placed on the exterior walls to reflect the constantly changing environment, for example the nearby water in rice paddies, and change the perception of the structures throughout the day. “In alignment with its heritage, the constellation of tearooms is also in harmony with the surrounding undulating terrain, thus creating a landscape in which the indoor and outdoor expand seamlessly, like the flow of a river under the Milky Way.�

Vedanta UK For its latest, highly-ambitious lighting project, Nulty worked in close partnership with office fit-out specialists Modus and interior designer DaeWha Kang, on the new London headquarters of Vedanta, a global mining and metal company. This is a flexible executive space in Mayfair, where the boardroom, offices, meeting rooms and hall of mirrors transforms into a large open-plan events space. The 860sqm multipurpose project is characterised by its chameleon-like design features throughout, where the lighting plays a key role in affecting the metamorphosis of the space. In the reception area, the lighting, provided by Flos and Optelma, is composed of a combination of indirect and low-glare spotlights creating pools of light on the attractive white marble floor. The eye is then drawn toward a large sliding door, a light portal framing the monolithic sliding door’s perimeter. The door opens up into a multipurpose space, which has


the look and feel of a celestial otherworld. The main iteration of this space takes the form of a hallway of mirrors with six working areas and the chairman’s office extending off from it. A series of seven large elliptical lights, referred to as ‘moons’, are recessed into the sweeping, three-dimensional Corian ceiling, emphasising the ethereal quality of the light filtering in. Produced by Nulty Bespoke, the moons serve a wide variety of functions, providing five dynamic white effects for day-to-day use, and a multitude of colourchanging effects when the area opens up as an events space. There are 68 individually controllable pixels within its thermally formed, dome-shaped, matt acrylic diffuser. The perimeter of the fixture is surrounded by a ring of eighteen small Brick in the Wall downlights, extending its versatility further by projecting pools of light, designed to replicate shafts of daylight.


At the end of the hallway, banquette seating with integral linear uplights from Osram, Optelma and Linea Light illuminate the walls and window reveals. Throughout the floor are tiny DGA uplights with internal faceted crystals creating a particularly radiant effect, designed to be employed during evening events. The clever interplay between low and high-level lighting, creates a dynamic atmosphere throughout. There is one larger version of the elliptical fixture in the chairman’s office, referred to as a ‘sun’, measuring 1800mm in diameter and surrounded by 30 individual spotlights. The innovation of the space is illustrated best when the mirrored walls and meeting room partitions disappear, moving on a series of tracks into the ceiling. The walls are stored in pockets to the side, transforming the various rooms into a single, large open-plan events space with all fifteen moons and the sun revealed. Separate from this dramatic events space is a boardroom featuring a rectangular architectural feature in the ceiling, housing acoustic fabric panels punctuated by small downlights. One of the meeting rooms serves a dual purpose as a bedroom, with a Murphy-style bed appearing from within a feature joinery wall. The lighting within the wall transforms the space from a bright working space into a warm, domestic feeling bedroom at the touch of a button. All lighting functions are run by a bespoke DMX control system ensuring a smooth and quick transition. The technical interface controlling the lighting has been designed to be highly user-friendly. Lighting requirements can be adjusted by scene selections as well as traditional dimming or separated into more specific functions via wireless tablets. By designing the controls to mimic the elaborate flexible wall systems, the controls remain easy to use no matter which of the many spacial configurations are deployed. Lighting plays a crucial role in the emotional state of visitors to the space, as algorithms and motion sensors allow light to track users’ movements, providing a type of ethereal companion in this thoughtfully designed project.

CF Toronto Eaton Centre Bridge Canada The lighting design for the CF Toronto Eaton Centre Bridge, created by Speirs + Major, focuses on the dual aspects of creating a powerful after dark identity, while also creating a memorable experience of the journey between the two architecturally contrasting buildings it links. Walking onto the bridge, designed by Wilkinson Eyre Architects, pedestrians are enveloped in a warm glow. LED Linear lighting integrated into the deck enhances the torque and twist of the bridge’s surfaces and joins lines in a simple and apparently effortless reveal of the unique geometry. As the proportion of glazing increases near the modern Eaton Centre, the glow from the soft frit to the glass helps to soften and balance the effect of this transition from the opaque (heritage) to the transparent (modern). A very soft line of light to the deck encourages movement through the space without competing with the architectural forms. The exterior overhanging the sidewalk is a backlit soffit, an important visual aspect in the streetscape. This glows homogenously to create a positive experience for pedestrians below. The lighting equipment is housed in an innovative independent mounting system


that sits unobtrusively beneath the bridge decking, simplifying access for maintenance. This system, which was engineered by MBII, contains a pulley arrangement so that the light tape housed within a custom formed tube can be rolled in and out from the side of the bridge. Although technically challenging, the light has a beautiful simplicity that contributes to the character of the city, clear wayfinding and functional light levels. The project was characterised by a high level of design team collaboration between Speirs + Major, Wilkinson Eyre and executive architects Zeidler on the choice of surface textures, along with innovative siting details that help to conceal the sources of light. The result preserves the clean lines of the architecture and contributes a genuine sense of magic to the pedestrian experience. The public response to the bridge design has been exceptional, generating a tremendous amount of buzz on architectural blogs and social media since it’s opening. Many reviewers and social commentators specifically mention the dramatic and positive effect of the lighting effects on their experience of the bridge.

Arcos Brazil Arcos is a cocktail bar located in the foundations of the historic Municipal Theatre of Sao Paulo. The main architectural feature, the vaulted arches (arcos, in Portuguese), lends the space its name. Originally the space served as part of the natural ventilation system of the theatre. However, with the introduction of air conditioning the ventilation shafts were obstructed, and the space became obsolete. In the 1980s it was refurbished to be used as an events room, which was seldom used, but in 2015 a public tender was issued with a view to giving the space a new lease of life. Facundo Guerra and MM18 Arquitetura’s vision for a cocktail bar with live classical music featuring performers from the Municipal and State Orchestras was the winning bid. London-based design firm There’s Light worked on the lighting design, alongside local practice Studio 220v. The architecture consists of a series of columns, arches and vaulted ceilings, varying in direction and ceiling heights. Moreover, the building is protected for its architecture, historical and cultural significance by the Municipal, State and Federal Governments.


This unusual space, particularly for a Brazilian city that only thrived from late 1880s, creates a certain confusion for users. Therefore, it was key for the lighting to provide a sense of bearing and orientation to the space. Being completely underground, thus void of any natural light, another aspect of the lighting design was ensuring the space felt inviting. Additionally, as a basis for listed building consent, all modifications to the space needed to be easily demountable, and made to be an obvious addition, rather than discreetly fading into the historical architecture. This naturally posed a challenge for all installations and insertions to be carefully considered for the two key spaces – the main bar and the events room. Countless mock-ups and tests were conducted on site over a three-year long project programme. Due to the lack of any external light spills, and being underground, the correct balance of light levels and colour temperatures between the various lighting effects proposed, became imperative for the success of the scheme. In the main bar, there are two main lighting features, the backlit tables at 3000K for a crisper feel, inspired by the Overlook Hotel

bar of Stanley Kubrick’s The Shining, and the uplights to the arches at 2700K, warmed even further with the use of filters. LED tapes and profiles from Brillia illuminated these features. Cocktails and food are served in translucent materials, which glow beautifully when placed on the tables. For the events room, a lounge environment was envisaged, with domestic furniture and a more intimate ambience, thus the lighting proposal changes focus from the arches to the perimeter. In order to achieve this intent, the lighting design team developed a bespoke reinterpretation of wall-mounted candelabras with sober orthogonal proportions. Two variations were designed with two and three arms, made in aluminium and powder coated in matte black. With an intentionally dim light at the tip of the arms, in reference to candle light, at 2000K, these candelabras are dotted around the perimeter and columns. Both spaces are controlled by an automation system that provides numerous scenes and ultimately saving energy.

MS LIGHTING DESIGN Owned and operated by Marcus Steffen, MS Lighting Design is a growing London-based studio. Working across all sectors, with a specialism in residential projects, MS Lighting Design takes pride in close collaboration with clients to ensure lighting is tailored to each individual project. Old Pye Street London, UK This small one-bedroom flat was a challenging site to work with. The ceilings were low and solid, and MS Lighting Design had to make it feel light and airy. The client requested a boutique hotel feel and really wanted to do something different with the space, much to the delight of the designers. Due to the solid ceiling throughout most of the flat, it was decided to work with surface mounted lighting, while minimising any drops due to the low height. Linear LED strips, concealed by pelmets, were included in the design, providing soft washes of light into the space when dimmed, but can be turned up to give bright light when required. Integrated lighting into the furniture and specific decorative table and floor lamps helped provide the task lighting for the space. The bathroom was the one area with a suspended ceiling, so a wash of light was created along one wall, while keeping all light fittings as discreet as possible to provide a sense of serenity and peace for a home in the bustling city.

Clubrooms Birmingham Airport, UK No1 Lounges are a collection of premium airport lounges across the UK’s busiest airports. The top-tier lounges, the ‘Clubrooms’, were developed in 2017 to offer the ultimate departure experience, and in 2018, they were redesigned. Starting with the Birmingham airport Clubroom, MS Lighting Design was appointed to create a scheme that would highlight the features in the space. The brief was to reduce the number of downlights in order to achieve the right lighting levels, which were too high before. There were many technical constraints to overcome, such as a suspended, perforated ceiling which needed to be accessible, with air flowing to comply with fire regulations. A custom fixing was created for the egg crate spotlight, which was designed to reduce visibility and allow positioning in any location. The custom solution also allowed the light to be adjusted within the space. The lighting was integrated and hidden as much as possible, allowing it to subtly wash light onto surfaces, while being controlled to maintain the atmosphere. Custom-designed joinery houses the lighting. A scene setting system has been used to automate the whole space, ensuring the lighting correctly illuminates the lounge at any time of day, as well as adjusting for the time of year.



High-end Residential Clapham, UK Situated in South-West London, this high-end residential project was a complete refurbishment of an existing house with the addition of a basement area. The client offered design flexibility, with a loose brief of creating a mix of traditional and contemporary in the existing house, with a more modern feel in the extension and basement area, with cleaner lines and iconic style pieces. The lighting was completely tailored to the interior design, enhancing the architectural elements, such as the skylights and door openings, and the decorative elements including the curtains and the fireplace. The aim was to offer discreet lighting – concealing the fittings as much as possible, complementing the design aesthetic, rather than becoming a distraction from it. Where feasible, concealed LED strips were used, alongside plastered-in downlights and low-level lights and channels, carefully positioning all fittings to ensure the right areas of the interiors were illuminated. Whilst functional, the lighting also creates mood and atmosphere when required, such as when entertaining guests, so the design encompassed both high and low-level lighting positioned in the rooms. The AV supplier incorporated a Rako lighting control system, which enables scenes to be set to ensure the client always experiences the best lighting possible.

High-end Residential Southfields, UK At this luxurious property in Southfields, South West London, the project was a renovation of a ground floor and garden area as part of an existing dwelling. The client had a specific brief to produce a lighting scheme that would complement the incorporation of both traditional elements and raw architecture, such as exposed brick. Taking this, the design aimed to conceal as many of the light fittings as possible, using plastered-in fittings or incorporating them into the joinery. Where wall lights and pendants were added, an exhaustive review process was carried out with the client to find precisely the right items to complement the materials they were to be

MS Lighting Design mounted on or next to, ensuring the desired lighting effect. Some specifics from the project include the beautiful entrance hall with patterned tiles, where the lighting has been kept simple, using decorative fittings and a few discrete plasteredin downlights. In the formal living room with a feature fireplace, this is complemented with two decorative wall lights and a matching pendant to frame the fireplace and highlight the patterned wallpaper. The attention to detail and diversity in the lighting design throughout the property ensured the brief was met.

Based in London, UK, MS Lighting Design was founded by award-winning lighting designer Marcus Steffen. Working closely with clients, MS Lighting Design tailors lighting to each individual project, using it to bring out each client’s passion and make it a feature. Rather than seeing light as just one part of a project, MS Lighting Design believes that light is an integral piece that enables all the other parts of the project to work. MS Lighting Design’s extensive experience in lighting means that it can create beautiful design and provide the technical support to back it up. Working across all sectors, the firm specialises in residential lighting, with founder Marcus Steffen authoring Residential Lighting Design, a book that introduces the tools of the lighting designer and explains how to produce a lighting design for a home.



John Martin After announcing his retirement following a 50-year career, in which he spent the last ten years working as Public Policy Consultant for the IALD, arc spoke with John Martin on his career highlights, and the increased profile of the lighting industry over the last decade. How did you get into lighting? I am not a lighting professional by training or experience. Starting in 2008, I served as a public policy consultant to the IALD. The skills required for that role included an appreciation of the importance of lighting design and an understanding of lighting technology, but it was actually better for me not to be a practicing lighting professional. That way, I did not bring my professional slant to any of the controversies or policy discussions in which the organisation was involved. Can you give us a brief overview of your career to date? Since I have just officially retired after 50+ years as a working professional, it’s difficult to be brief. The short list of my professions includes: teaching, legislative aide, education lobbyist, electrical contractor, corporate training director, and my work for IALD. You were IALD’s Public Policy Consultant until the end of last year what did this role involve? As IALD’s Public Policy Consultant, I worked on several fronts to support lighting design and lighting designers. While the role evolved considerably over my tenure, the key elements remained constant: establish relationships with other organisations, work with governments and government officials at all levels, monitor governments for actions that could affect either lighting design or the business of lighting design, seek opportunities to raise awareness of the importance of lighting design, and communicate the impact of laws and regulatory proposals to IALD members. How has the lighting industry changed and developed during your time with the IALD? Three changes stand out over the past ten years: the rise of new technology (solid-state lighting); the consolidation and changing markets for manufacturers; and the growing public awareness of the impact of light and lighting on human health, productivity and comfort. At IALD Enlighten Europe last November, you spoke of the ‘terrific progress’ made in raising awareness not only of the IALD but of lighting regulations around the world. How has the IALD been working to raise such awareness? During the past ten years, the IALD has increased its visible involvement in policy issues in many ways: building relationships with other designand construction-related organisations around the world, from the ILD and SLL to the IES in North America and Australia, Lighting Europe in the EU, as well as architectural societies, entertainment lighting associations such as PLASA or PEARLE and interior design associations; placing IALD volunteers on energy-code-writing groups wherever possible; and working with government officials in the EU, USA, Australia and elsewhere to raise the profile of the IALD and architectural lighting design in general. IALD’s ‘secret sauce’ has been our volunteers, members of the IALD who articulate the value of their profession, and who are able to analyse regulatory and legislative proposals to determine their impact on the practice of lighting design.


What will this increased awareness mean for the lighting industry as a whole? What impact has it had so far? I hope that the increased awareness of lighting design helps the lighting industry become more visible (pardon the pun) to other design professions and to regulatory bodies. At the same time, we are entering a period in which light and lighting are more in the public consciousness than ever before; the combination of technological change (SSL) and increasing awareness of the importance of light in human health mean that lighting-related policy issues are no longer confined to energy efficiency, which has been the case for the past 40+ years. The growing issue of legal conflicts related to light pollution and the different ways in which these are tackled from a regulatory standpoint globally, is also showing the relevance of good lighting design. To date, the impact is that IALD has gained an official role as a “spokes-organisation” in places as diverse as Australia, the EU, and the U.S. State of California. In addition, IALD is playing a consulting role for organisations such as the International Well Building Institute (IWBI), authors of the WELL rating system. Congratulations on your retirement! How do you plan on spending your retirement? Professionally, I continue to be involved with the California Energy Alliance, an assembly of disparate organisations - from manufacturers to design professionals to labour unions - that are working together to improve California’s state-level energy regulation, which is widely seen as a leading indicator of how similar regulations will evolve in other U.S. States and at the national level. Personally, grandchildren and travel are already keeping me busy! What would you say has been the highlight of your career to date? I feel very privileged to have had the opportunity to work with IALD members from around the world over the past decade - they are uniformly interesting people, often insightful business owners, and imaginative thinkers. I have worked with IALD members from at least a dozen countries, which has itself been an education for me! Finally, what do you think the future holds for the lighting industry? Larger manufacturers will continue to consolidate and seek new revenue models, which in turn will put continuing pressure on independent lighting designers. In many arenas, “lighting as a service” will become a dominant business model. Smaller manufacturers and lighting designers may well make common cause to provide their own variations on the “lighting as a service” model. The policy importance of lighting in buildings will no longer be about the energy used for lighting. Increasing awareness of the power and importance of light may lead to an increasing demand for better lighting from building occupants and the public at large. The continuing debate will be, “Just what is ‘better lighting’?” As the cliché goes, ‘stay tuned for developments’!

200CENT Tiny… Really Tiny! This LED spot has a diameter of just 26 mm, which makes it as small as a twoeuro coin. And thus, the name… 200Cent. Plus, it’s Powerful… really Powerful! The 200Cent’s light output is 750 lumens, which makes it more powerful than a traditional 50 W halogen spot (and at least 88% more economical). And all that with the best quality. The colour consistency is perfect (two-step MacAdam), so you will never see the slightest colour difference between spots. The colour rendering (CRI 92) is also outstanding, which ensures that objects are illuminated true to life. Tiny and Powerful? Yes, it’s possible. The 200Cent is an optimal crossing of outstanding technology and minimalistic design.

working in lighting to promote their passion and achievements, narrate their career path and goals, celebrate their work and elevate their profile in the lighting community. Starting with lighting designers, the

scope will expand to include women in all

aspects of lighting - education, journalism, manufacturing, art and research.

(8th March), will begin with interviews with

female lighting designers completed by Light Collective.

New Global Services Jenni Gillard and the Gillard Group have developed ‘Lighting as a Service’, a concept designed to help the industry prosper from the uptake of LED, avoid pitfalls and contribute to positive global environmental outcomes.


he Gillard Group is an internationally recognised architectural lighting design firm based in

Brisbane, Australia. Established in 2005 by Jenni Gillard, the firm provides day and night lighting solutions that combine art and science.

Alongside this, Gillard Group pioneered and

launched ‘Lighting as a Service’ (LaaS) in 2015.

LaaS uses design, business cases and technology to deliver sustained value, with a focus on optimising the volume of LED luminaires and

reducing energy consumption (carbon footprint) and fixture wastage on the environment.

Gillard is a multi-award-winning architectural lighting designer and lighting consultant (CLD, IALD and IES). She also fills her time as a

lighting judge, contemporary artist and art dealer, and was a former art gallery manager and university lecturer. Since founding Gillard Group, she has become a pioneering woman in the Australian lighting design community.

Gillard was the first woman to graduate in a degree wholly devoted

to lighting; graduate with a Masters in Lighting; qualify as a Certified Lighting Designer (second person in Australia and seventh in the

world); start, build, lead and grow an independent lighting design studio and become a full member of the International Association of Lighting Designers (eighth person in Australia).

The firm’s first lighting project was to relight the interior of the State

of Queensland’s oldest continuous-use church – Ann St Presbyterian.

Previous Page The transition from backstage to the auditorium itself shows how the rich new colour palette has created a warm, welcoming environment for patrons. Above The refurbishment saw the introduction of a newly-designed orchestra pit. Split into two mechanical lifts, the front four rows of seating can be raised or lowered depending on need. Due to the pit’s close proximity to the stage, beam control was critical, so 18 Degrees designed a series of apertures to project narrow beam LED theatre lanterns, in the form of ETC’s Source 4 fixtures, to illuminate and zone the area accurately. Below An integral aspect of the new lighting scheme was to improve visibility and accessibility for theatregoers, even in low-light conditions, while celebrating the theatre’s beautiful architecture. Linear lighting from LEDFlex was embedded into handrails and arm rests to allow for improved visibility when accessing the walkways.

To create the new environment and pay tribute to the heritage and

architecture of the theatre, 18 Degrees’ design approach was to provide layers of light that would present the auditorium beautifully, yet have subtle

variations in function. This was realised through general, comfort, decorative and accent lighting - a response to the performative nature of the space.

General illumination was provided by the installation of more than 200 new

Lucifer Lighting downlights. Carefully integrated into the historic fabric of the building, after gaining permission from English Heritage, who oversaw the restoration works, this light created a soft, even illumination to the space,

improving distribution and increasing the illuminance during general, day to day use. This means that heritage lighting now only needs to be used for

performances. Dimming, distribution and illuminance levels were all carefully plotted, along with extensive onsite testing for performance and colour rendering.

All heritage lighting within the venue was retained - a key component of the design plans - as 18 Degrees decided to refurbish and repair the fixtures,

replacing the old halogen lamps with Global Design Solutions LEDs. The use of LED lighting throughout provides increased functionality, while ensuring a

more conscious approach environmentally for the venue, leading to a longer term, more efficient lighting solution.

For these heritage fixtures, the original 1930s cabling was concealed within

the architectural fabric of the building. Accessing this would mean breaking into the Grade II listed building, so instead 18 Degrees continued to use this wiring with new LED lamps and drivers especially designed for this application.

New comfort lighting, in the form of nearly 300 new LEDFlex linear lights

integrated into the end of row arm rests and handrails, provides low levels of light during the performance to allow for improved visibility when accessing the walkways. Totally concealed, these linear lights only offer illumination

into the aisles, while the low level of light ensures that patrons are not lit or distracted while watching a show.

The final component of the new lighting scheme was the newly designed

orchestra pit. Split into two mechanical lifts, concealed seats within the pit can be raised or lowered to provide an additional four rows of seating, if needed. Due to the pit’s close proximity to the stage, beam control was

Balancing Act Dividing his time between teaching and his architectural practice, Miami-based Jorge L. Hernandez speaks to arc about his exhibit at the Venice Biennale, focusing on the integral role that lighting plays within architecture, both physically and spiritually.


hile the architecture headlines are regularly

dominated by the latest designs for the newest, ultra-modern, up-to-date buildings, there are some in the industry that prefer to pay tribute to the great works of the past.

One such architect is Jorge L. Hernandez.

Based out of Miami, USA, Hernandez is both

a professor and practitioner of architecture, balancing his time

between his eponymous architecture firm, opened 32 years ago, and teaching at the University of Miami.

“I’ve always had one foot in the classroom and one foot on the

sidewalk, so to speak,” said Hernandez when asked of his dual career paths. “I often get asked ‘which one would you keep, and which one

would you give up, if you had to?’ And I always answer the same way,

which is you don’t know what you don’t know - I don’t know another reality.”

Born in Havana, Cuba in 1956, Hernandez emigrated to Miami in

1962, and completed his Bachelor of Architecture from the University of Miami in 1980. He then went on to the University of Virginia,

where he studied design and architectural history and completed his Master of Architecture. Following graduation, Hernandez was asked

by the Dean of the University of Virginia to stay on and teach, which he did for two years, before moving back home to join the faculty at

the University of Miami as a professor of Architecture - where he still teaches to this day.

Owing to his multiple commitments, Hernandez’s architectural practice remains relatively small at ten people. As such, a lot

of his work is done collaboratively, as he explained: “On larger

projects, I’m brought in to do the conceptual work, then stay on in a supportive role to ensure that the design is faithfully executed. I

don’t want a firm of 120 people. I want to still be able to go in and out of the classroom.”

Human Centric Lighting The New X Factor? Following a workshop held at last year’s [d]arc room, Asst. Prof. Dr. Karolina M.Zielinska-Dabkowska IALD, IES, CIE, MSLL, RIBA, reflects on the known and unknown aspects of Human Centric Lighting (HCL).

the world. Part of this rapid change involves a concept called Human Centric Lighting

(HCL). At last year’s Light+Building, it was the buzzword, with nearly every second

manufacturer’s stand claiming they had figured out the special

formula necessary to create perfect HCL illumination. But how can

such claims be legitimate when we know so little about the full and

complex impact of artificial lighting on human biology, let alone how to responsibly apply this new approach?

Many experts in this area of research are aware that their knowledge is still fragmented, that they don’t have the whole picture and thus, are unable to draw final conclusions that can guide the design and

implementation of responsible LED lighting. This includes Dr Russell Foster from Oxford University: the neuroscientist who, with his

team in 1991, identified the eye’s third photosensitive cells, called intrinsically photosensitive retinal ganglion cells (ipRGSc) whose function, unlike that of rods and cones, is unrelated to vision. He

recently stated: “We can’t develop human-centric lighting until we

know what impact light has upon human biology across the day and night cycle.” Also according to Dr. George Brainard, a well-known

researcher in the field, “light works as if it’s a drug, except it’s not

a drug at all,” so if this is the case, why don’t we follow the medical

All modern medication requires various testing on animals and

or more to complete all three phases of clinical trials before the

licensing stage, whereas, with lighting, we have omitted this stage. Rather than apply the precautionary principle, we allow ourselves and our clients to be unwitting guinea pigs without knowing or

even anticipating the long-term consequences. Are we as lighting designers practicing medicine without a licence?

There are several reasons why our understanding of the impact of

light on the human body is so limited. Firstly, the discovery of new

photoreceptors is relatively new; less than two decades, and there is insufficient interdisciplinary research in this area.

Secondly, we’ve grossly underestimated the powerful influence of light on biology and therefore incorrectly assumed lighting plays a minor role in health and wellbeing. Now we know the opposite is true, we need to be more resourceful in our research because

medical ethics prevents direct study on humans (unlike other animal subjects, researchers cannot, for example, induce rod and cone loss to investigate the ganglion cells in humans, neither genetically

nor with chemicals). We do know from numerous research on test

animals and the information obtained, that artificial light at night can have serious negative effects, including alterations to the

circadian clock, patterns of behaviour, or biochemistry, as well as an increase in various diseases.


human centric lighting

What’s become obvious in recognising the limits of our understanding about this topic, is just

how complex it is to mimic natural light, and that far more research is required to identify what’s needed to apply artificial lighting safely and effectively. This is why the Human Centric Lighting

workshop, held during [d]arc room on 19th September 2018, took place – to initiate the important

discussion between UK-based lighting practitioners, representatives of established lighting bodies, lighting industry partners and the general public.

The panel featured Mark Ridler (Director of Lighting at BDP); Rebecca Weir (Creative Director at

Light IQ); Stephen Lisk (former President of SLL and current President of CIBSE) and Iain Carlile

(Associate at dpa lighting consultants and President of the SLL) and also included myself as chair of this discussion, a practicing lighting designer, researcher and educator (see Fig.1).

If one had attended this event and expected a clear and obvious solution, they might have left

disappointed, as the focus was on the known and the unknown aspects of HCL. As indicated by

the sheer number of participants, including John Lincoln of LightAware (a registered UK charity

dedicated to supporting light-sensitive people), as well as numerous comments from the audience, it was obvious this subject is a serious challenge for many.

To further complicate matters, lighting practitioners, responsible for designing artificial lighting are overwhelmed with recently developed metrics such as: circadian action factor, melanopic sensitivity, melatonin suppression index, circadian light, etc., and they need clear guidance

on which ones to use and why (see Fig.2). In Europe numerous associations with various task

groups including SLL, CIBSE, and CIE are working around the clock on appropriate guidelines and standards; and overseas, IES is doing the same. But without proper, repeated long-term research involving humans of different ages, sex and sensitivity towards LED artificial lighting, all the proposed metrics might be just guesswork.

Figure 2 The above diagram indicates the potential complexity of artificial light on humans, involving many interconnected factors that create a cascade effect. © Shutterstock

The Definitions Human Centric Lighting (HCL) is defined by LightingEurope as a type of lighting that “supports

the health, wellbeing and performance of humans by combining visual, biological and emotional benefits of light”. This is achieved by dimming and a change in Correlated Colour Temperature

(CCT) of a smart light source (most likely an LED), to mimic the appropriate levels of irradiance

and spectrum of sunlight throughout the day. But how can this be achieved to a satisfactory degree when daylight constantly changes?

If we look closely at the whole HCL concept, gaps in our comprehension become obvious. How

can we confidently claim to replicate daylight/sunlight and therefore provide its many benefits

without taking into consideration all of its known components including: light intensity, timing,

duration, spectral power distribution, irradiance, the angle where light comes from, and perhaps

also even the variation of light due to different seasons? We also need to be aware that just like with the discovery of ipRGSc in the human eye, there may also be important aspects of our biology and factors regarding the properties of sunlight that we haven’t yet considered or even know exist.

LED lighting technology has been designed to reduce energy consumption, and therefore minimise global warming, but there are certain inherent shortcomings with this technology as well as a

great deal of misunderstanding about the unique characteristics of light produced by LEDs, that directly conflicts with the core principle of HCL. For example, the most energy efficient LED

lighting follows the natural patterns and properties of day and night. During the day, natural light via windows and skylights should be provided and only supplemented with artificial light where there is insufficient daylight available. Such light is of a continuous

3000K, and as little blue light in the spectrum as possible. Ideally,

at night, artificial lighting should be kept to a bare minimum with a recommendation of light with a spectrum greater than 600nm (amber, red colour). All forms of this lighting at night should be

indirect, preferably positioned at a low level, flicker-free and also dimmable.

The challenges for lighting designers As our clients follow multimedia and become more knowledgeable about the impact of natural and artificial light on their health,

wellbeing and productivity; they want to apply this new knowledge, supported by technological advancements in LEDs, in their

projects. They are given promises by lamp, luminaire and control manufacturers, based on claims that HCL can solve all sorts of

problems (without understanding the complexity involved), and often they want to achieve circadian credit from WELL Building

Standard (a performance-based system for measuring, certifying,

and monitoring features of the built environment that impact human health and wellbeing, through air, water, nourishment, light, fitness, comfort, and mind).

This means discrepancies result between the client’s expectations and what professional practicing lighting designers can actually

deliver based on scientific knowledge. We have a moral responsibility


Conclusion: What are the next steps and action plans for the future? The lighting community needs to acknowledge health and wellbeing as a major principle in engineering and the design of light and

lighting systems – Primum non nocere (ang. first, to do no harm).

Additionally, we must recognise that the effect of lighting on human health based on current research is not fully understood, and accept

too, that its complexity requires further discussion and the necessary means to better understand it, necessitating financial support to

conduct such independent research, the application of appropriate research tools and development of methodologies used.

It’s imperative we come together to define what is required in terms of design related questions (too many researchers and scientists from academia conduct research studies without being aware of what’s needed by lighting professionals). As LED technology is constantly evolving, relevant questions need to be framed in a

practical fashion in the form of applied research. Respected Model for Applied Research Collaboration (MARC) (see Fig. 3) between Lighting Professionals (1), Professional Associations (2), the

Lighting Industry (3) and Academia (4) need to be established.

paced society requires a lighting scheme that environment it is situated in.

Liquid Light, created by ÅF Lighting, is a design concept that brings light to life, by creating a visual environment with its own identity and unique expression.

ÅF Lighting is making it its mission to take part in designing

the cities of the future and make them more environmentally friendly, efficient and navigable.

The concept of Liquid Light originated during collaboration with architectural firm Snøhetta and the construction of Powerhouse.

Located in Trondheim, Norway, Powerhouse is the world’s

northernmost energy-positive building, where Liquid Light has ensured sustainability and an inspiring visual

environment. The building is designed to be an office building that produces more energy than it consumes; the

construction is designed so that the excess energy produced

during the building’s operational time will exceed the energy used to produce the building materials, operation and eventual demolition.

needs and energy efficiency, ensuring unique lighting

“The concept is inspired by natural light and based on the

philosophy that the lighting should respond and adapt to the changes that are physically happening throughout the day.

“The absolute main challenge in the Powerhouse project was to reach the high energy goals without compromising the

quality of lighting. Some energy goals were conflicting with

each other, so we encouraged the client to deviate from these constricting criterias and instead ensure a good working

environment where those who want can choose to use a desk lamp, as well as ensure an overall low power consumption used for the functional lighting,” explained Thea Collett, Architect and Senior Lighting Designer at ÅF Lighting.

“Further challenged by the demands of keeping a low energy consumption, the idea of having the light triggered by real time data, such as people moving around in the building,

prompted the development of the lighting concept Liquid Light.”

Morten Jensen, Country Manager of Norway for ÅF Lighting, explained the decisions behind the colour temperature

projects, the Liquid Light concept will play a crucial role in creating the natural

well as unconventional data sources, such as

movement and automatically generated sine parameters and real-time data that

determines these organic light scenarios,” explained ÅF Lighting.

Following on from Liquid Light’s conception, ÅF Lighting joined up with Snøhetta once more, this time to create an underwater

dining experience at Under. The restaurant, due to open in March 2019, is located on the

coastline of the Norwegian village, Båly. The concrete rectangular structure is semi-

submerged five-metres under the North Sea and provides diners with a one-off underwater eating experience.

“From day one, the design group has been a part of the client’s vision. All the designers

were part of an advisory group that acted as ambassadors and gave the client input on professional skills.

“The project demanded full transparency in

Powerhouse, designed by Snøhetta, is an example of the potential future of architectural design that incorporates environmental considerations in terms of energy consumption. Using the Liquid Light concept by ÅF Lighting, the building is the northernmost energy positive building that creates a natural working environment to boost productivity and relieve stress symptoms.

nature around, with an aim of creating a visual

specially chosen to encourage marine life such as biodiversity.

The structure of the building played an important factor in the lighting design, as it was key for the designers to illuminate the space but discreetly

disguise the fixtures, so as not to distract from the overall completed look.

“The whole building is mostly covered by seawater and leaning into the sea,” described Jensen.

“The ceiling is curved for acoustic purposes, so there was a special need for a tailor-made

solutions for each luminaire. We ended up with more than 400 fixtures positioned exactly with

vertical output and into a grid formation with no space for flexibility, which brought with it some challenges in the detailing.”

“Our main challenges were to maintain a natural

light and to create a safe atmosphere at the bottom of the ocean for the visitors,” added Jensen.

“Due to the minimal amounts of daylight below

the sea and with a natural reference to the theme

of the restaurant, we envisioned that the lighting would float into the room where it is needed. It is

restaurant and designed in harmony with the ecosystem.”

“By use of LEDs in a matrix located in the ceiling,

the light sources are small with good glare control, which makes them almost invisible. Technically, Liquid Light consists of data harvested from

different sensors, and for instance in Under, infrared sensors detect heat, while acoustic

detectors respond to sound frequencies in the room. The data is then interpreted and

transformed into light scenarios constantly

changing and adapting to its milieu and the people using the space,” reflected ÅF Lighting.

“Liquid Light is designed to bring the wild outdoors into our civilised world. Just like air quality,

thermal comfort and acoustics, lighting is a precondition for people to live and work

comfortably in a healthy building. With Liquid Light, we embrace the challenges of designing human centred lighting.”

The building is divided into distinct levels

that are split into different active spaces. The ground floor is an extension of the exterior Kansalaistori square, drawing visitors in

to an open and clean space. The first floor is home to a host of workable spaces and the top floor is nicknamed book heaven.

The book heaven is a bright and airy floor

that is filled with natural daylight through the floor-to-ceiling glass windows and

skylights that perforate the undulating roof.

the architecture seamlessly, disappearing into the background. Some exceptions appeared, for example in the bathrooms, where pendants were suspended from the ceiling to create another layer of light in the space.

“There were fixed requirements for lux levels depending on the function of each space and the light fixtures had to fulfil the


seasons and weather conditions, the lighting throughout different times of day and seasonal lighting conditions.

“There were some new concepts to be implemented in this

particular project. The overall design concept was based on the idea that the building itself would not be illuminated. Instead,

the functions inside were made visible through the glass façades using light. This was a new concept and we had to develop

a lighting control programme that would support this idea.

activating the city space around it,” described Mahlberg. “In the cinema hall for the first time we used fibre optic

lighting combined with LED lights to achieve the design intent with continuous light dot lines on the walls and

the ceiling marking every seating row. This worked out

fine in the end, even though we had our doubts regarding the possible difference of the quality of light from these

different light sources. This is also the first project where white neon light tubes were used in the signage.

“One element was the colour of the light, normally

4000K is used as a standard but sometimes it gives a

rather pale and dull atmosphere, especially with wood involved. So, we did some testing and found out that

3000K or 3500K worked better in some circumstances.”

There were some custom made solutions throughout the

building made to accommodate the lighting fixtures, such as the bookshelves that were modified so the lighting fixtures could contribute to the overall lighting of the book heaven.

A hanging bubble made of ETFE (Ethylene

Tetra Fluoro Ethylene, a plastic construction

material) hangs in the southern entrance way and acts like a lantern guiding visitors in.

“Lighting brings clarity, warmth and readability to the

spaces and helps one to orientate through the building. The final result is fantastic and works very well with our initial ideas. There are still some adjustments to

be made in the lighting control, but we are very happy with the overall finish,” reflected Mahlberg.

vibrant districts of Vienna, nestled around the Rochus Market, stands the

exquisite new Post am Rochus – a skilful blend of

new construction and listed building that cleverly fuses tradition and modernity.

Architects from Schenker Salvi Weber, alongside feld72, combined old and new to come up with a design that blends beautifully into the densely built-up area around the Rochusplatz Square,

right in the middle of Vienna’s third district. The

listed building from the 1920s has been seamlessly integrated into the new construction using

floor-to-ceiling glazing and striking grid-like

openings, while the old and new parts have been

physically connected by a multi-storey atrium-like architectural link.

This new ensemble is further emphasised by

the light. Working closely with architects from

Schenker Salvi Weber and feld72, lighting planner and designer Christian Ploderer has crafted a

multi-layered lighting design for every area. The inclusion of Zumtobel in the project has enabled

the realisation of a holistic lighting concept from one source – a concept where daylight combines

Panos Evolution luminaires sunk by the lighting designer into concrete elements around the

The building complex is additionally flooded with daylight from two large skylights, while light

visitors and delivering a contemporary lighting contrast.

Round Ondaria wide-area LED luminaires in the conference rooms, combined with additional corner-mounted Diamo spotlights, deliver a

different kind of light. Despite their surface area, the extreme flatness of Ondaria means that the

fittings take up minimal space, which in turn helps generate an open and interactive atmosphere.

When it comes to visual comfort, Mirel Evolution

solutions have been specified with two different

light colours: 4,000K direct light and 3,500 indirect

The integration of the existing protected building into the new construction has helped the Post

metropolitan context of Vienna in every sense,

becoming an essential part of both the cityscape and urban life around the Rochusmarkt. And

this coming together of tradition and modernity is continued with the award-winning interior

architecture. Old and new are skilfully merged in an approach based on functionality, aesthetics

and wellbeing. The lighting designs by Christian

exhibition area that reflected its positioning and client base.

This led to Cornershop Design being

instructed on the creation of a new interior concept, designed to engage clients and

employees using an array of display and lighting techniques.

With lighting key to the project, Cornershop Design partnered with Unibox to realise its vision, due to its experience of integrating lighting into displays.

A central aspect of the ‘experience’ was an animated ceiling display that brought the space to life. Unibox’s patented Kinetik

Northern Lights in the evening, helping to provide context to the area. Further

animations can be easily uploaded if required in the future. By creating a display relative

to the time of day, the new design increases visitor and staff awareness.

Lee Isherwood, Creative Director at

Cornershop, said of the Kinetic installation: “Designing an experience space within a

working office provided a challenge around how the space behaves when there is no presentation or visitors.

“Having the experience on a constant loop was not an option from a staff wellbeing

perspective, so for the downtime experience we focused on how we could use the

technology to make the space a more

human-friendly place to be. Turning the

ceiling screens into virtual skylights was one great way to achieve this.”

Alongside this innovative display, several bespoke displays were created, including

vinyl wrapping process found in aerospace manufacturing, for added durability and aesthetic appeal.

David Judge, Head of Experience Design at

Cornershop Design, added: “We’re incredibly happy with the launch of the space, and

more importantly the team at Businesswise Solutions now has a space that reflects its position. Plus, working with the team at

Unibox gave us the freedom to design truly innovative displays that used light to great effect.”

Thanks to their flat-ray technology, the BackLED modules provide only uniformly bright, glare-free panels can be seen, rather than the light sources themselves, despite the larger LED spacing.

In addition to this pleasantly diffuse light, the solution enables

Light School During the Surface Design Show, the ILP alongside LED Linear hosted a series of ‘Light Talks’, with topics ranging from human centric and workplace lighting, to ambient media and using light as a ‘brand’. We caught up with some of the speakers to get their thoughts on the industry’s current hot topic. Martina Algana & Philip Copland Nulty Human-centred lighting should be at the heart of all good design. It’s important to understand that it’s not just about circadian lighting. The use of dynamic white fittings isn’t enough on its own to constitute a humancentric scheme. While they may be useful tools, they should only be used as part of the wider design strategy, that considers all of the user’s needs. Although we are very happy to see the uptake of this style of fitting, and are fascinated by the science, it is only one of the many tools that designers can use to ensure lighting schemes are designed for the people using the spaces. Our talk - A Moonlit Walk in the Workplace - looked specifically at workplace lighting, and how best to design for more holistic, humancentred spaces. It discussed the challenges of designing for the constantly changing modern workspace, while considering the evolution of technologies both in lighting and building design. A human-centred workplace in terms of lighting, to us, involves connecting with people on a personal scale. It can’t be a simple boxticking exercise. The design from the start needs to be based around the needs and wants of those who will be using the space. The benefits that human-centred lighting would give to workers would be a pleasant environment to work in, as we spend approximately 93% of our life indoors. Nobody wants to spend eight working hours a day in a bright, uniform, cold space, so an intervention in terms of lighting can help to create a unique space for the users that they actually enjoy and benefit from being in. In addition to this, with full controllability of the luminaires, we have the opportunity to modify the intensity, quality and colour temperature of the light to best work with our biological response, in order to create a truly human-centred approach that will make a standard workplace a more comfortable space to be. However, human-centric lighting is far too often only linked around colour temperature with daylight to maximise our productivity and aid our sleep patterns. While there are undoubtedly benefits to understanding this from a biological perspective, it’s important to also consider the moral questions this raises. Is it right to artificially manipulate people’s surroundings and do we have enough understanding in order to correctly utilise this to its best effect? It’s also vital that this area is led by the science and not overly influenced by manufacturers and suppliers attempting to lead trends in the market.

Brad Koerner Koerner Design There is a poetic aspect of light that nourishes our souls. To quote Richard Kelly, light “stimulates the body and spirit, quickens the appetite, awakens curiosity, sharpens the wit…”. We are not machines with operating manuals and prescriptive engineering conditions that can secure our ‘wellbeing’. We need lighting that both shapes our emotions and responds to our wishes, that drives our understanding and interpretation of the world around us. That is the essence of lighting for our wellbeing. Lighting designers need to transition to experience designers. Design for human experience first, and the technical design of lighting – along with acoustics, ergonomics, UX, digital media, biorhythms and a variety of other specialties – readily follows.


human centric lighting

Christopher Knowlton 18 Degrees Human Centric Lighting is an ambiguous term, used within lighting without clear definition of it’s meaning, while some use it to mean the application of spectral tuning of lighting to affect the human biological system. We would define good lighting design as responding to the human experience and therefore human centric lighting. As the lighting profession gains greater scientific understanding of the role that light plays on the human circadian system and biology more widely, there is a desire by some to use artificial light in support of these biological processes. If it’s possible to affect positive change on the human body with the application of light, then we must assume it’s possible to generate a negative effect also. Are the current standards in light making people unwell? We might think of these as badly lit spaces. However, currently it’s very hard to apply metrics that accurately describe a well or poorly lit environment successfully. When we look at some of the claims being made by manufacturers we are concerned about the way in which complex science is being distilled into a commodity to sell. Looking to the medical industry, where the introduction of even the most innocuous of drugs takes many years of rigorous study and trials before administration to the general public. We have to question how the science is being used to support the claims of benefit. As a profession, are we applying the same level of rigor to our practice as, say, a pharmaceutical company? We also feel there is a part of the discussion which rarely, if ever, is discussed. This is around the ethical use of this type of lighting. If we were to assume that we could create lighting that promoted and maintained the circadian system. It’s not too much of a stretch to imagine someone wanting to boost productivity with a small change here and there. In a totally dystopian way you could even imagine longer working days and buildings without windows. Perhaps as a design community we should be championing a change of societal and work norms to promote a healthy work life balance rather than trying to fix a problem related to poor building design or working practices.

Benz Roos Speirs + Major To me, human-centric lighting means designing for the human eye. The more we understand about our eyes in terms of contrast ratios and peripheral vision, the better we can create experiences in light that resonate with people. In essence, lighting design is a composition of various tones of brightness - similar to painting or photography. Our eyes experience luminance levels relative to each other, not as absolutes. Therefore, it is the variation in luminance - or visual contrast ratio - that is much more important than the actual intensity of light. For example, the screen of a phone that appears to be super bright after dark is perceived as very dim when viewed in direct sunlight. The brightness of the screen itself has not changed, but the contrast ratio compared to its surroundings has. I see human-centric lighting design as composing visual experiences with suitable levels of contrast for the type of experience we want to enable. The illuminance value of the key element in a space is the basis for this. In a typical office space, the most important element is the computer screen. The average screen has an approximate illuminance value of 300cd/ m2. Knowing this base value helps to determine appropriate brightnesses for the peripheral surfaces, such as ceiling and wall planes. Reducing the contrast between all these surfaces will help reduce eyestrain and so support productivity. Conversely, in retail spaces, we often aim to increase the visual contrast ratio to create a dynamic composition that draws attention.

Bringing the trail of light back through the city centre, the sites brought new stories and interpretations of the town’s history and local landmarks.

The theme for this year’s event was Energy.

Site one was located at Dyer’s Bridge (Fägeribron), a

bridge in the city centre that crosses a small river that was once the original water supply in the area. The

workshop heads that managed this team were Mieke

a lighting designer for Licht Kunst Licht, Arup and Delta Light among others. She was also a student

first time back to the Swedish town since. Nielsen, also from the Netherlands, is a lighting designer

and owner of Beersnielsen lichtontwerpers, brought


The team of ten students and two workshop heads incorporated both the bridge and the water to create

a relaxing yet eerie atmosphere. The team wanted to draw history into its piece by referring to a fire that destroyed the original bridge in the 1800s. A new

bridge was built during an industrial turn, where the water from the river was used to drive a mill nearby. In following years, the river around the bridge was

used a lot in the textile industry. The bridge’s name derives from this era and translates to ‘dye workers bridge’. This is represented by a giant white canvas

that hung over the water, allowing reflections to be

projected onto the fabric that moved naturally in the wind. Shadows that played on the canvas were also

representative of people from the local community. Colours from the dye would stain the waters, which brought both beauty and pollution to the city.

As a whole, the team wanted to portray various

types of energy, from water, wind, fire and human

team used a lot of historical context as inspiration for their creation. The team also had to be careful not to cause any damage during installation due to the historic importance of the site.

Taking the layers of history and the original use of

the space of craft shops, iron trade, upholstery and stables, their aim was to use light to reveal these

The Amsterdam Light Festival once again returned this winter, bringing with it a collection of beautiful artworks and installations to light up the Dutch city.


rom 29 November until 20 January, the seventh

edition of the Amsterdam Light Festival took over the Dutch capital with a series of light installations and artworks made by artists from all over the world.

The 53-day exhibition, which saw 30 installations throughout the historical city centre of Amsterdam, revolved around the theme

The Medium is the Message, the famous statement by Canadian

scientist Marshall McLuhan. The idea behind this statement is

simple: the way we send a message is at least as important as the

message itself. In this instance, light served to convey a message, while the city of Amsterdam was the medium for telling stories.

The rich history, unique architecture and extraordinary inhabitants of Amsterdam make the city as a medium very suitable for

telling remarkable stories. On behalf of the festival, art historian Koen Kleijn went in search of these stories, collecting them

in a ten-part series available to view on the festival website.

In these stories, Kleijn identifies the connection between the

the festival, scheduled to take place from November 2019 to

January 2020. Installations for the next instalment will operate under the theme Disrupt!. Usually seen as inconvenient,

disruptions can also be positive and sometimes essential to trigger the need for change to take place. This is something that organisers will be hoping to see at next year’s festival.

The installations took inspiration from current film and TV trends, wanting to incorporate the essence of Stranger Things, Game of Thrones

Making Light History AGB Events create an array of lighting events across Australia, celebrating the country’s cultural history in public buildings and the great outback.


GB Events, established by Anthony Bastic twelve years ago, is the main driving force behind multiple lighting events across Australia.

Its most recent venture Beauty, Rich and Rare took place

in the National Library of Australia in Canberra - the title of the

exhibition takes its name from the lyrics of the Australian national

anthem. Held from September 2018-February 2019, the event was an immersive sound and light experience that showcased the flora and fauna that is unique to the continent.

Celebrating the sites and wonders witnessed by Joseph Banks, the

botanist, scientist and illustrator that travelled on the Endeavour,

the exhibition provided an immersive experience for visitors across a 20-metre wide, 2.5-metre high screen.

The free event space was commissioned by the National Library of Australia, created by AGB Events and supported by Panasonic

“I started AGB Events around twelve years ago with people’s lives and had an informative/educational/ entertaining component,” reflected Bastic.

“My background is in creating and producing largescale public events and I am passionate about this field. I had also worked for a time in a corporate

events agency that churned out what I considered to be meaningless events one after the other. This

experience gave me the impetus to start my own company on my own terms.

“It has been extremely hard at times but the reward when literally millions of people are able to

experience something that you played a part in

Osram installed 780 special luminaires equipped with 100,000 LEDs

throughout the church, and with the introduction of new intelligent

lighting control, the lighting for the church - which covers an area of 22,000sqm, can be quickly and easily adapted to predefined lighting scenarios. With the new LED lighting, for example, the mosaics in the domes of the side aisles can now be seen down to the smallest

detail, while numerous works of art that had previously disappeared in semi-darkness now shine in a light never before experienced within the Basilica.

As well as emphasising the artwork within the sacred building, such as the mosaics covering more than 10,000sqm, the new lighting enables visitors to read without straining their eyes. Further to

this, the domes in the small side aisles, among other things, were previously almost unlit; now, the new lighting concept sets the

stage for them in the best possible way. Details that had never been visible before in the 500-year history of the church - details that

even art experts were unaware of - are now visible without disturbing reflections.

The new lighting system in St. Peter’s Basilica is the latest in a series of collaborations between Osram and the Vatican, with the German

building has now been upgraded to high-performance, durable Erco LED projectors.

Designed by Pietro Palladino and Cinzia Ferrara, of Ferrara Palladino

Lightscape, the project was commissioned by the Veneranda Fabbrica del Duomo di Milano cathedral workshop, the historic organisation concerned with all operational aspects of the cathedral.

Using the ‘Erco individual’ service, series products were transformed into individual lighting tools, adapted to the local requirements. More than 400 Lightscan spotlights with specially increased

luminous flux illuminate the cathedral’s remarkable façade. Compact Gecko spotlights were also used to accentuate the Gothic verticals, pinnacles and tower spires.

maintenance remains a constant focus of the Veneranda Fabbrica del Duomo di Milano.

The new exterior lighting scheme comes four years after Ferrara Palladino teamed up with Erco to illuminate the church’s monumental interior for EXPO 2015.

Through the use of the German manufacturer’s LED lighting tools,

a complex lighting solution was implemented inside the cathedral, that reduced the operating costs for maintenance and energy on a

permanent basis - a key issue for the Veneranda Fabbrica in view of its formidable responsibilities working with limited resources.

The old lighting system had consisted of 175 floodlights, each with 400W metal halide lamps, which had been mounted to the base of the vault at a height of up to 33-metres for a uniform illumination of the interior. Although the most economical solution in its day,

the technology had, by today’s standards, become out-dated, and

the system lacked aesthetic appeal. However, the low maintenance

and energy efficiency of current LEDs, combined with the precision


and light quality of Erco’s LED lenses, gave lighting designers a new scope for design.

The new lighting concept uses LED luminaires from the Parscan range, solving a variety of different lighting tasks with suitably nuanced power outputs and light distributions.

Whereas the old system used a cool light colour resembling daylight, the new lighting with neutral white LEDs in 4000K creates a more

pleasant ambience that renders the surrounding surfaces in the most natural colour.

The lighting concept forms a consistent hierarchy of perception by

using brightness contrasts in the space: discreet horizontal ambient

lighting combines with brighter illumination for the vaulted ceilings, thereby reinforcing the sense of height and lightness as principal characteristics of Gothic architecture.

Defined light accents direct the attention of the visitor onto the

altars, pulpits and column capitals so richly adorned with sculptures. The result gives worshippers and tourists alike a tangible experience of the vast dimensions and artistic quality of the sacred space.


Small Yet Precise Hot off the heels of its success at the 2018 [d]arc awards, David Morgan puts Precision Lighting’s tiny Atto range under the microscope.


hen the author of a successful book series

on how to gain entry to medical and dental schools founds an architectural lighting

company, which goes on to create a series of

award-winning and innovative products, it is clear there is an interesting story to be told.

While Joe Ruston spent some of his career in

education, he has always had a passion for engineering and product

development. His degree in Engineering from Cambridge University was followed by an MSc in Guided Weapons Systems, and he then went to work as a Weapons Engineer in the Royal Navy.

In 2000, Joe and his son Alex founded Precision Lighting, as a UK spin off from an older US-based lighting company, Translite, in which Joe had an interest. Translite was sold to Lightolier at around the same time that Precision Lighting was born.

Based in London, Precision Lighting currently shares facilities and staff with sister company Remote Controlled Lighting (RCL). RCL

grew out of a custom product request to Precision Lighting in 2001

for remote controllable motorised lighting systems, and since then, the company has seen steady growth from two to 35 employees, all working on projects across the globe.

Precision’s focus has always been on manufacturing high quality display lighting systems for museums, galleries and retail

applications. The range includes a remarkably wide variety of

spotlights including some older types for MR16 halogen lamps, as well as many based on LED light engines. All the Precision

Lighting spotlights are NC machined from aerospace grade 6063T6 aluminium, which is particularly suitable for anodizing with a

consistent flawless finish. The sophisticated product design in the spotlight range is impressive, with full 360˚ rotation and rotation

the 2018 [d]arc awards. The Atto range was developed as a response to requests from lighting designers to make the existing Precision Lighting Pico range, originally introduced in 2011, even smaller.

features, usability and quality of the Pico range that designers

minimalised all the best features, including lockability, bearing aided rotation and constant torque tilt mechanism and combined them

with a thermally efficient LED and optical package to produce the Atto.

The 12mm diameter of the Atto is defined by the size of the lenses

used. Precision appear to have used a modified version of the Ledil Lisa 2 range of lenses, which although tiny, produce high quality

distributions and lit effects. The lenses are changeable on site by

unscrewing the spotlight front, although some care would be needed to avoid damaging the single Osram Oslon LEDs, used in the Atto range.

Osram’s Oslon LEDs achieve a CRI greater than 90 even for the more complex R values, R9 (reds) and R13 (skintone), which is ideal for high quality display and museum lighting applications. The light

engine incorporating the LEDs is tiny, with power being transferred to the LED through vias in the FR4 PCB. The adjustment feel is

smooth with just enough friction, and the locking movement is easily achieved with tiny grub screws requiring a 1mm Allen key.

Precision’s Atto collection features a variety of spotlights, an ultra-

The spotlight options include surface mount with a neatly detailed for display cases and a new miniature jack system, Minipoint, that

enables the spotlights to be easily changed and repositioned on site. Atto offers a beam range of 16˚-90˚, ensuring there is a suitable

solution for every miniature accent lighting scenario, and finishes

include matte black, satin white, anodized silver, satin and polished brass and oil rubbed bronze for whatever finished look the designer requires. These options, combined with the features, aim to ensure flexibility at specification and post installation.

Already this miniature range has been used in a variety of notable projects including Harrods and Fortnum and Mason. Hundreds of

Atto luminaires have also been used in a jewellery lighting project in the Forbidden City in Beijing.

Precision Lighting has created one of the smallest display lighting

ranges available without compromising the quality of the lit effect,

adjustability or mechanical detailing with its Atto range. Already well received in the lighting design market, this deserves real commercial success.


Book reviews

Light Reading We take a closer look at a couple of the latest books to hit the shelves for the lighting design community, including the new SLL Lighting Handbook. SLL Lighting Handbook 2018 SLL A major drive has been underway across the lighting profession to update the existing SLL Lighting Handbook. This work has involved more than sixty people with some twenty-five chapter editors and nearly forty reviewers and technical auditors. These are mostly members of the Society of Light and Lighting (SLL), drawn from over forty companies involved in lighting, including manufacturers, consultants and universities from across the UK and overseas. Leading the effort has been Paul Ruffles, ex-Chair of the SLL Technical and Publications Committee and Honorary Fellow of the Society of Light and Lighting. Widely established as a first stop for anyone seeking information on lighting, the previous edition of the SLL Handbook was published in 2009. Chapters on vision and light that were featured have now been removed, and will be included within the brand new SLL Code for Lighting, due to be published later in 2019. Additionally, the sections that looked towards the future have been removed, as time has shown that trends often move faster than predicted. The remaining chapters have been reviewed, updated and rewritten, with the addition of thirteen brand new chapters and four appendices, making the SLL Handbook one of the most comprehensive guides to interior and exterior lighting in the world.

The Art of Architectural Daylighting Mary Guzowski The Art of Architectural Daylighting, by Mary Guzowski and published by Laurence King, is a survey of twelve buildings that reveal the potential of daylighting to create beautifully illuminated spaces. During the past decade there has been a tremendous growth in daylighting analysis methods, allowing designers to meet ever-higher standards. But in relying too heavily on these methods, there is a risk of reducing daylighting design to a quantitative exercise, overlooking the qualitative, aesthetic and experiential aspects of design. The Art of Architectural Daylighting reveals how architects have bridged the poetic and practical potential of daylighting to create exquisitely illuminated spaces. In this book, twelve buildings are examined using photographs, drawings and plans. Each case study also includes technical analysis diagrams, created using specialist software and not seen anywhere else. Featured architects include Renzo Piano, David Chipperfield and Steven Holl. The Art of Architectural Daylighting is available to order at the Laurence King website.

Senzafine A.A.G Stucchi Senzafine is A.A.G. Stucchi system with all that you need to make an endless light line possible inside Multisystem tracks. The system is provided with various lengths, that match perfectly one to other, thus avoiding any visible junction of light. The different available opticts opal/ microprismatic/UGR<19/lenses together with the various colour temperatures guarantee a wide choice and the maximum freedom in your lighting projects.

Concrete Kos Astro A simple round or square geometric shape, Astroâ&#x20AC;&#x2122;s Kos downlight has a beautiful polished concrete finish. The Concrete Kos is individually cast by reinforcing raw concrete with weatherproofing additives, producing a robust and authentic product with natural imperfections and its own unique finish. Kos is perfect for blending into any architectural setting and can be ceiling mounted in both interior and exterior spaces thanks to its IP65 rating.

Matrix Augenti A linear recessed fixture, the Matrix is equipped with secondary optics for different light distributions, which is useful for raising the lighting of façades. It has architectonical or frosted glass elements for a diffused distribution that, together with the glare control, make it suitable for pedestrian paths. Available in LED with fixed or dimmable output (Dali, 1-10V, Push) or in tunable White/RGBW for DMXRDM.

Ink System Linea Light Group The Ink System is made up of several versatile items, united by the same concept. The elastic and thin cable, in the stretched version, houses a high performance stripLED and acts as a conductor on which it is possible to hook different devices: light profiles with diffused emission or UGR <19 thanks to special darklight cells, adjustable spotlights and pendant lamps. The range includes wall/ceiling paths, modular modules-channels with various junctions and endings that house the conductor cable and transform it into an elegant graphic sign.

200Cent Brick In The Wall The 200Cent LED spot is now also available in a 26x26mm square version, which makes it as small as a two-euro coin, hence the name 200Cent. Despite its small size, it remains powerful, running at up to 750 lumens. The colour consistency is perfect (two-step MacAdam), and the colour rendering (CRI 92) is also outstanding. The 200Cent is an optimal crossing of outstanding technology and minimalistic design.

Cosmos Lenses Khatod The low profile Cosmos lenses for COB LEDs with LES range from six to 22mm, and come in three sizes: 50, 70, and 90mm. They offer a full range of beam angles and meet MR16, PAR30, AR111 requirements. The frosted finish of the narrow beams makes the light flux smooth, diffused and very homogeneous. Perfect for luminaires in different kinds of environments, living spaces and any interior rooms, the lenses are easy to install, either using their holder or alone by exploiting the mechanical parts of the lighting fixture.



Omnia Nexo Luce Nexo Luce’s Omnia series features powerful uplights, downlights and projectors, which are able to supply up to 24W. It has a sleek body starting from 10.8cm in diameter and 7.5cm in depth. The COB version of Omnia hosts a new generation of Bridgelux LED and reaches 160lm/w with a variation of narrow, medium, wide and asymmetric optical systems. The other option of the product hosts CREE Power LEDs PCB with either three or nine units. The light beam angle ranges from 3.5-86˚. The 3.5˚ lens is able to produce an ultra-narrow beam that can reach up to 50 meters high.

Intono L&L Luce&Light Intono is the new wall-mounted outdoor fixture that comes in four different sizes and single or double beam. The body is a minimalist cylinder that connects to the wall by a sinuous double curve. The neutral and adhering surface allows it to be painted in the same finish as the supporting wall. It can also communicate with smart speaker devices over Wi-Fi using ZigBee protocol, and can change lighting scenarios according to the music. Rated IP65 and IK08, LED or COB light source, wattage ranges from 2W to 20W, CRI 80 and CRI>90, colour temperature 2700K, 3000K and 4000K.

and innovative design. One of the latest additions to the

glittering skyline of the district is the 251-room Grand Millennium

Business Bay hotel, prominent by its sleek, modern architecture and dramatic, yet subtle lighting scheme.

The project’s lighting design was developed and implemented by Nexo Luce, known for its well-coordinated and flexible lighting

solutions. The Italian company’s international team of designers and engineers has been working on this project from the initial concept and studies to the supply of the overall lighting products.

Nexo Luce provided both exterior and interior lighting for the project. The exterior lighting covered the hotel’s four façades, highlighting its architectural details as well as the landscape, public pathways,

pool decks and car park ramp. The interior lighting covered technical and decorative lighting including public spaces, lobby, F&B outlets,

ballroom, meeting rooms, gym and spa, back-of-house areas, suites, guestrooms corridors, and bar areas.

During the day, natural light penetrates into the building through

the windows, while at night the 100-metre-high hotel turns into a

gleaming point of light. To highlight the exterior façade during the

night, Nexo Luce created a lighting work of art with its harmonious white and cyan colour sequence, blending with the local bay

environment and impressively underlining the character of the building.

large role in the façade lighting of the project was given to OVO 18UN; a product designed by Nexo Luce that creates a powerful lighting

beam, equipped with an ultra-narrow optic of 3.5˚ and the ability to reach up to 59 lux at 80-metres.

The façade linear lighting in cyan distinguished the central spine

of the building. The pergolas positioned at the guest balconies on the upper levels were lit in a way to provide the necessary visual connection between the architectural features. At the hotel’s

entrance the concept was realised through recessed linear lighting

that ‘draws’ the structural lines of the attached canopies. The cyan

pin lights with elliptical lenses were evenly distributed on each side of the façade, playing the role of a bridge between the entrance and the spine of the building.

Among the other external spaces, the ramp leading to the hotel car

park is enhanced with ground linear lights, creating a continuous line effect to delimit the pathway.

In total, the external lighting plan includes more than 500 light

fixtures. While the internal spaces contain more than 2,000 technical luminaires that range from architectural to technical products used to either provide the general lighting, accentuate main functional spaces, or give more prominence to the decorative lighting compositions.

“There is a crack in everything, that’s how the light gets in.” Leonard Cohen

What: Sleeping under the Northern Lights. Where: Northern Lights, also known as Aurora Borealis is a phenomenon visible in the night sky near the Earth’s magnetic poles. Finland and other Nordic countries are great places to go hunting for the light show. Booking a glass igloo for the night will make the observation more comfortable. How: It all begins with an explosion in the sun. As a result of that the solar wind blows particles to Earth. These charged particles become trapped in Earth’s magnetic field and get transformed into this visible phenomenon. Green is the most common light colour to see, and sometimes blue, purple and red colours also occur. When: March and September are the best times for viewing the natural light show. Check the aurora activity forecast and try to avoid the time of the full moon. Snow and light pollution will diminish the experience. Why: When nature offers you a light show comparable to the net capacity of dozens of nuclear stations, it is a moment of magic. Picture © Juuso Hämäläinen
