When lighting designer Amarasri Songcharoen (aka Marci Song) of Seam Design was looking for the best lighting fixtures to light the 500-year-old Raphael Cartoons – a series of large art pieces by Rafael on exhibit in London’s Victoria & Albert Museum – she knew she needed something special. It had to be something that would output minimal or no ultraviolet light, as well as provide a perfectly lighted atmosphere for a giant mirrored sculpture that was to be installed as part of the London Design Festival.
As part of the month-long Precision & Poetry in Motion exhibition, design agency Barber Osgerby developed a system of two giant mirrored aeronautical “wings” that were suspended in the room and would slowly rotate on motors, altering the reflections of the Raphael Cartoons as they did. To light the artworks, she used 16 ETC Source Four LED™ Series 2 Lustr® fixtures, controlled by an ETC Ion® control desk.
“We were asked to provide a lighting strategy and design for the room and of the sculpture to reveal the Barber Osgerby sculpture in its best light,” says Song. “We also had to pay careful consideration to providing appropriate light sources and light levels for priceless art pieces, which are on loan from Her Majesty Queen Elizabeth II.”

The sculpture’s wings were clad with a highly polished mirror finish. Song says that the best-lit effect was to light the elements surrounding it, rather than lighting the piece itself – but since the floating objects occupied most of the view to the ceiling – the existing high-level lights for the artwork would be blocked periodically, making them unsuitable for this installation.
Seam Design’s proposal therefore involved a completely new system for lighting the room, using striking illumination to the Raphael Cartoons and a dramatic wash to the floor. The Cartoons are then reflected on the wings above them, so that they can be seen by the people standing underneath.
“Through its slow rotations,” describes Song, “the sculpture is disorientating and mesmerizing, emerging from high level in an uncanny way. The dramatic light enhances these experiences.”

Each of the cartoons, which were commissioned by Pope Leo X in 1515 and were intended to hang below Michelangelo’s famous ceiling in the Vatican Palace, are up to 3.5m high by 5.3m wide (11.4ft x 17.4ft), which meant that even in the very large 46m long x 25m wide (151ft x 82ft) gallery, Seam had just 70cm (2.3ft) of clearance between the wings and the face of the artwork’s surfaces. They therefore needed a product capable of very wide beam-throw that still allowed for an ability to control light spill to the walls – plus, with ultraviolet light being a danger to artwork – they needed a low- or zero-UV fixture, making LED the obvious choice.
“ETC’s Source Four LED Series 2 Lustr with a 90-degree lens tethered to an ETC Ion desk met all of our requirements,” explains Song. “We were able to shutter and frame the light to enhance the artwork. The success of the lighting scheme is that the polished wings rely heavily on the illumination of the cartoons and the floor to be perceived. In the intimate darkness of the room, with focused light taking your attention to the artwork, the sculpture becomes very mysterious – almost imperceptible until they catch the light and reflections illuminate their surfaces. This is an incredible dimension to add to the experience of the installation, which is an epic feat of engineering in its own right and exhibits attributes entirely beyond its impressiveness as a machine.”
Seam worked closely with ETC and Hawthorns, who installed the lighting and helped to program the color tuning and settings. The fixtures were set to a very warm 2,600-degree color temperature – the color of candlelight – helping the Cartoons appear almost like tapestries as they may have looked in the 16th century.
Attending the launch event, ETC’s regional manager for the UK and Ireland, Mark White, was asked a number of times if the lighting on the cartoons was really LED and not tungsten. “LEDs are usually associated with the blue-white cold light fitted these days to bathrooms and the like,” he says, “so to see apparent candlelight coming from the Source Four LEDs was an eye-opener.”
“ETC and Hawthorns were very responsive, particularly on a fast-track install of two weeks with schedules changing day to day as we were getting near the opening,” concludes Song. “They were amazing teams to work with. And we heard that the museum likes it so much that there was talk to make the fixtures part of a permanent installation for the gallery.”

We asked, you answered. The Lighting Controls Association recently conducted a survey of regular site users (subscribers to the LCA newsletter, lightingCONTROL) to determine how well we’re doing our job and what kinds of features you might like to see developed in the 2015. Results are based on 110 respondents, which were filtered to 86 after removing manufacturers.
The most popular reason respondents visit the LCA website is for general education about controllable lighting (28%), followed by keeping in touch with what’s new in the field (25%).
Seventy-three percent of respondents say their visits to the LCA website have influenced their selection of control strategies, while 70 percent have selected products based on information they learned at LCA. Sixty-eight percent say these visits have influenced selection of products made by LCA members.
The average respondent is more than “somewhat satisfied” with all forms of content offered by LCA, with the monthly special reports, newsletter and Education Express being most important to the average respondent.
Respondents were asked what lighting control topics are most important to them from a list. The most popular are LED control, control system design and dimming control. LCA will focus on these and other important subjects in 2015.
Respondents were also asked to evaluate potential new site features from a list. All were considered more than “somewhat valuable,” with the most valuable being best practice guides by building type and a generic troubleshooting process guide for lighting control systems. LCA is currently considering this input as part of its 2015 planning.
Thank you to all who responded. Your feedback is essential to ensuring LCA provides good education value and offers tool and resources that help you select and specify lighting controls.

Designers were tasked with providing a low maintenance, energy efficient “lecture hall” in a new academic building that included as many “auditorium” performance features as economically possible. This was achieved with fifty 86W, 5376 lumen, 40° spread, diffuse lensed, DMX dimmable, 3500K LED cylinders suspended between wood panels providing illumination for various learning and performance functions.
House lighting controls are integrated with the performance dimming system, providing seamless controls during performances for smooth fades or quick pops. Each fixture is independently addressed allowing the stage manager to focus light exactly where desired.
LED linear fixtures at the top and bottom of 8 windows and 5 faux windows set the mood, mimic daylight or augment performances, bringing the “stage” into the audience.
In the center of the audience, the control booth is equipped with a performance grade DMX controller, allowing the stage manager complete control of house and performance lighting.
When the stage manager is not present, untrained users can operate a simplified password protected touchscreen controller to recall and save presets, raise and lower shades or adjust lighting zones.
Color coded LED controls are provided at each entrance and catwalk for pre-programmed scene calls and zone toggle; these lockout and change to blue when the room is set to “performance mode”. The system includes a Wi-Fi interface for control via mobile applications and wireless remote.
Fixtures align with the raised ceiling above the stage.
Fluorescents are switched backstage and above catwalks for maintenance.
Blue LED aisle lights provided for performance operators.
White LED aisle lights provided for performance egress. During an emergency, select circuits including non-dimming emergency-only LED cylinders are energized by generator via an automatic transfer switch.

The National Electrical Manufacturers Association (NEMA) recently updated LSD 64-2014 Lighting Controls Terminology
. This white paper, which was originally published in 2012, was updated to clarify terminology related to daylight responsive controls.
NEMA LSD 64 defines terminology related to controls for lighting systems for non-residential and residential applications. The goal of LSD 64 is for NEMA definitions to ultimately be used as the definitive reference for codes, standards, and legislation. This will eliminate the creation of new meanings for already defined terms, will minimize misapplication of controls terminology, and will eliminate the need for customized glossaries and terminology sections.
This document was developed by reviewing every known description for lighting control terminology, and represents ultimately agreeing upon best definitions. The working group reviewed definitions from documents such as American Society of Heating and Refrigerating and Air Conditioning Engineers standards, Illuminating Engineering Society of North America Handbook, NEMA guides, and all energy codes in use at the time, including California Title 24.

Lighting retrofits, layered with advanced control strategies can improve occupant comfort, enhance productivity, deliver greater building efficiencies and often result in lighting electricity savings up to 60% or more. New light sources, specifically LEDs and fluorescents, continue to provide opportunities for better light quality, lower electricity bills and payback in as little as two years.
As you prepare to save all that energy, think about these five tips for making product selection and installation easier too.
1. Wireless. Wireless lighting control systems have come a long way, and even a solution as simple as a wireless occupancy sensor and switch can put you on the path to a 30% lighting energy reduction in just a few minutes. And wireless controls can be installed with little-to-no disruption to building occupants. Wireless control solutions can include occupancy sensing, dimming, daylighting harvesting and even automated shading solutions depending on your budget and energy-saving goals.
2. Apps. Specifically apps that simplify audits, proposals and return on investment calculations. It’s easier to make the right decisions when you have the right tools. Look for new apps that require only basic project information to provide lighting energy audits, lighting control proposals, bills-of-materials and projected ROI. Apps can save time and money and help you confidently choose a system just right for your building.
3. Scalability. Today the conference room, tomorrow the entire building. Look for control solutions that can adapt to your changing needs. Digital control systems typically offer the greatest flexibility, functionality and opportunity for expansion. Look for a lighting and shade control system that can be expanded easily, without replacing the existing equipment and without complex reprogramming. To ensure that the system can accommodate future growth, ask the manufacturer how easily it scales from a single control or small system, to a larger space or building.
4. Data. It’s one thing to plan for energy savings and another thing to actually see the results. Manufacturers now offer a variety of measurement and verification tools that help you understand how much energy is used, where, and when. Look for software tools that have the ability to log data about lighting use, occupancy and daylight. Make sure the software can be installed on any computer in your facility, offers an easy-to-understand graphical interface, and give you full access to the data without requiring you to send information off to a third-party. Effective systems put energy analysis at your fingertips, and improve your ability to predict energy savings.
5. Service. Let’s face it. Sometimes you get by with a little help from your friends. When you are selecting lighting and control systems, ask about available support services, online help, and customer service. Look for a manufacturer that offers 24/7 technical support…just in case. And if you are retrofitting a large space, or an entire building, consider the types of warranty and service options available to ensure that your investment is protected today, and for as long as you own the system.
A lighting retrofit can be greater than the sum of its parts if you plan appropriately, select a system with the future in mind, and have clear goals for system performance and payback.
