ARCHITECTURAL SSL • Chronicling the Advancement of LEDs in the Built Environment
GETTING COMFORTABLE. We crave comfort foods that make us feel good. Without realizing it, perhaps we wish the same thing in lighting. In trying to better define human-oriented lighting, let’s recognize homeopathic as well as prescriptive solutions.
AT THE FRONT In language, the right accent on right syllable makes all the difference. For buildings, it’s all about the right lighting strokes.

Outdoor Lighting Color Quality DOE SNAPSHOT ON OUTDOOR FIXTURES FINDS MOST MEET DLC REQUIREMENTS
Outdoor Area Color Quality and Power Quality Active Products Active Area/Roadway Active Parking Garage Active Canopy
Outdoor area applications offered some of the earliest low-hanging fruit for LEDs to make inroads in reducing lighting-related energy use, given the high-wattage lamps and fixtures targeted for replacement. As September 2017 DOE CALiPER Snapshot report on this segment notes, LED luminaires and retrofit kits have captured a significant share of this market and continue to show efficacy improvements, even at lower color temperatures. ABOVE: In all three categories, the greatest percentage of products (53% to 63%) have a CRI (Ra) value in the 70s. Depending on the specific category, between 41% and 49% of the listed outdoor area products have a nominal CCT of 5000K or greater. Between 29% and 38% have a nominal CCT of 4000K.
Like other Snapshot reports, this publication is based on analysis of the DOE’s Lighting Facts product list. Information in this list is provided voluntarily by manufacturers, based on their data for products tested in accordance with the Illuminating Engineering Society of North Amer-

category comprises approximately 26% of all LED products listed in the DOE’s Lighting Facts database – area/roadway products, alone, make up 21% of those listings. In the year since the previous report, researchers found that average luminous efficacy for products in the category had increased by about 9 lm/W, even as correlated color temperatures (CCTs) had decreased. As additional evidence of continuing improvement in outdoor/area products, researchers note that approximately 63% of those fixtures and kits meet output and efficacy specifications required for acceptance onto the DesignLights
ABOVE: For parking garage luminaires (left), higher output has been achieved by increasing input power compared to the first such products to be listed by LED Lighting Facts in 2010. For canopy luminaires (right), output has remained mostly constant over the past five years, with gains in efficacy helping to reduce input power.

were clearly inferior to the fixtures they were designed to replace. Today, however, outdoor LED fixtures can outperform legacy high-pressure sodium systems, using significantly less power for equivalent lumen output and better color rendering. And, LED versions can offer better luminous intensity distributions than lamp-based luminaires, so fewer lumens are needed to produce equivalent illuminance levels on surfaces being lit. The report’s authors conclude that these trends indicate a broader range of choices for specifiers, allowing for an improved balancing of competing needs.•

“WE NEEDED A SOBER AND DISCREET PRODUCT THAT COULD BLEND INTO THE HISTORIC ARCHITECTURE OF THE CATHEDRAL.” The aim of the general restoration project was to enhance, yet preserve, the entire historical and artistic heritage on display inside. The restoration first focused on the heart of the cathedral and then moved onto the side chapels. The latter work needed to not only welcome the millions of visitors that cross the catherdral’s threshold, but to ensure excellent levels of lighting and luminance ratios for the television cameras that transmit mass every week from the cathedral. Based on years of experience illuminating fine works of art and historical buildings, Targetti designed a lighting plan along with Zadikian that would meet these new criteria. “The original lighting that was installed years ago was no longer suitable for current expectations and needs. The use of outdated and miscellaneous materials, together with a lack of light, made it difficult to see the works on display and the lighting was too low for the television cameras that transmit services regularly inside the cathedral,” explained Zadikian. Targetti LED LEDÒ adjustable projectors were

LG Display has launched volume production of its new Luflex OLED light-panel brand with the inauguration of its new Gen 5 production line in Gumi, Korea. The plant’s initial production target of 15,000 units per month—a 30-fold increase over the company’s previous capacity—is expected to be ramped up even higher over time. The higher volume is intended to bring down per-unit pricing to make OLED lighting more competitive in the broader market.•

Betting Big on the LED Component Business Aldo Kamper CEO, Osram Opto Semiconductor
The move toward LED lighting systems continued to disrupt the bottom lines of traditional industry leaders as 2017 came to a close, with GE announcing plans to sell both its consumer lighting division and its tech-focused Current business, Philips (which now calls itself a healthcare company) selling off another 12% of its share in Philips Lighting (spun off in a 2016 IPO) and Osram Sylvania shedding its bulb operations. Osram too has moved out of the lamps business to reimagine itself as a technology company. In August, it acquired Boston-based intelligentlighting company Digital Lumens. And in November, its Opto Semiconductor division cut the ribbon on a new LED chip factory in Kulim, Malaysia.

the synchronization of each product.•
Because the statue plays such a notable role in the city’s tourist economy, Salotec Luminoplastia, a local Ecuador architectural lighting company, was challenged with replacing the current lighting scheme by designing and installing a dynamic lighting system to highlight the grand statue at night. With the complex exterior, including windows and columns, the company needed to create an all-encompassing lighting system that was calendar control-driven. To find the lighting products versatile enough to illuminate the statue, Monica Velasco and Miguel Salmon, Salotec Luminoplastia designers, investigated several lighting companies. The team reviewed numerous products that could provide color changing capabilities, precise colors and the ability for control-driven lighting to provide intricate lighting schemes for special occasions. Salotec Luminoplastia specified products from Los Angeles-based Acclaim Lighting. The products chosen have capabilities that effectively illuminate the different exterior layers. The assembly of lighting products took just one month beginning in October 2016. “The result is excellent, as the great icon of the Quito city is now visible from many points in the city,” said Miguel Salomón, Salotec Lumino-

The question on everyone’s mind now is: Can we apply light to make us healthier? Finding the answer begins with recognizing lighting as a multi-layered entity in our environment. This includes the consideration of non-traditional approaches that support the feeling of comfort and well-being through application of lighting strategies that follow prescribed methodologies, but support comfort and homeopathic approaches.
‘Comfort’ Lighting We crave comfort foods that make us feel good. Without realizing it, perhaps we wish the same thing in lighting. It’s a fact that several lighting design features are not founded on objectively enhancing human performance of health—but rather are applied to benefit an observer’s sense of space or style. The intent is to help occupants feel good in the spaces they occupy. Color effects, decorative lighting features and aesthetic lighting of space/architecture, are comfort lighting. These features create a feeling of intrigue and ALCHEMY OF LIGHTNG Cove and color effect lighting in Miami’s upscale Alchemist2 store, by G2J Design, absolutely deliver “comfort” lighting, creating a sense of intrigue and interest to shoppers.

ACCENTED COMMUNICATION By Vilma Barr, contributing writer
Accent lighting has long been a staple for two commercial consumer interactions—retail and dining. At retail, selected products receiving higher-power beams than their surroundings subtly attract a shopper’s attention and initiate a process of comparison with surrounding options. In restaurants, particularly those in the mid-range and above, accent lighting on the platters presented to the diner gain another dimension under the appropriately selected lamp. Now, with LEDs offering ever-broadening performance capabilities, accent lighting is both sustainable and enhancing. From their palette, lighting designers are applying illumination strokes that help to define time/place relationships, focus on customer experience, and branding.
Lascaux IV International Centre for Cave Art
Focus On Customer Experience Accent lighting can assist customers with wayfinding in stores of all sizes. Integrated with signage, accent lighting can set the emotional and visual stage to receive the message inherent in a display’s arrangement. Patterns formed by the arrangement of materials applied to walls and ceilings are part of the language that is directed to users to process information about the space they move through or occupy. In the Beer Boutique (p. 29), the openwork and floating appearance of the hanging light fixture above the sturdy table beneath offers visual contrast and ramps up customer expectations. By surrounding the table/fixture setting with product displays, the vignette becomes theater-in-theround, with open space for customers to become performers or spectators, depending on the event.
Expressing Time and Place Marking the opening in 2017 in the Dordogne region of France is Lascaux IV, a museum displaying a minutelydetailed reproduction of the fabled discovery of the cave drawings painted over 17,000 years ago. Lighting for the interior pathways in the exhibit area is programmed to flicker as did the torches of the Paleolithic-era cave dwellers who drew them.
WELL-ATTUNED LIGHTING Illumination is intentionally kept low as visitors progress through a sequence of lighting conditions attuned to how the eye responds.

Location: Montaignac, France Architect: Snøhetta Lighting Design: 8’18” Agency Sceneography: Casson Mann Stumbled upon by a teenage boy and his dog in 1940 in France’s Dordogne region, the caves at Lascaux with their colorful cave drawings, created over 17,000 years ago, were opened to the public after World War II. Although other caves from this era have been discovered, Lascaux became famous for the quality, diversity, color, and sheer size of its animal paintings. The original was closed in 1963 because of growing concern over their condition. A limited reproduction was unsuccessful in attracting visitors, and a third version is on a world tour. This fourth meticulous representation, completed in mid-2017, combines imagination, innovation, and technology. The building, designed by Snøhetta, is partially buried in the hillside near the original caves. Recreating them requires a change in light, acoustics, and humidity. Lighting consultants for the circulation spaces was 8’18” Agency, Paris.
A team of artists and sculptors from Perigord Facsimile Workshop in over two years reproduced 1,900 paintings including animals, signs and symbols, and one human with a bird’s head. The resin walls of the 9,700-sq.-ft. replicas are sprayed with a mineralfilled coating to reproduce the Paleolithic rock surface. Glass, in the façade and the roof of the orientation area, produces a series of contrasting effects of natural light and shade. Illumination is kept at a low level in the spaces housing the reconstruction of the caves.

world, Chen and fellow designer Sarig Shinar decided to carry the magic out of the children’s books and start a company that designs and markets light fixtures that are both fun and functional. Chen says that she always felt that there was “…something magical about light, and the relation of light and space.” The Deer Head fixture is crafted from aluminum and steel, folded into a wallmounted accent/art work that measures 15.7-in. × 14-in. when not illuminated, and 29.5-in. × 27.6-in. when turned on.
When interior designers Anthony Ingrao and Randy Kempner of Ingrao Inc. got their first look in early 2016 at the interior of what was known as The Campbell Apartment, it was barely dim. Their job was to give new life to the onceglamorous, 95-year-old space, carved out of a corner within New York’s landmark Grand Central Terminal. It is now under the management of the Gerber Group, operators of high-end bars and restaurants. Their plan was to replace the visual design cobwebs, divest its “JoeSent-Me” reputation, and take advantage of the traffic generated by the nearly halfmillion people who pass through Grand Central daily to attract more business to its bar and restaurant. With 25-ft.-high hand-painted Florentine-style ceilings, a wall expanse of leaded glass, and a massive manor house-size stone fireplace, the 1,500-sq.ft. space is an architectural pastiche. It was leased in 1923 to financier and investor John William Campbell who used it for many years as a business office and reception center for colleagues and friends. Operation of the existing Beaux Arts Grand Central Terminal, opened in 1913, was taken over by the region’s Metro North system. In 1994, it initiated an encompassing upgrade and restoration throughout its neglected interiors and added stores and restaurants to become a shopping and dining destination as well as a transit hub. Renamed The Campbell, Ingrao’s designers fashioned their interior plan to capture its environmental lure while adding new esthetic and functional elements. Their treatment of the illumination was accomplished primarily by accent lighting. Pairs of custom green quartzite and brass sconces are mounted on pilasters on both sides of the room. Additional lighting appears at the base of and behind the bar, and along the fireplace mantle. Reflected light from fixtures at the top of the pilasters illuminates the ceiling’s artistry.

D Light, Italian-Style Alitalia’s lounges at Milan and Rome airports are skillfully orchestrated to tell its customers they are in a special environment, created for them, that imparts a distinctive sense of place. Alitalia is betting that they will carry this impression with them to become their airline of choice when next they need travel to an Alitalia-served destination. Soft contours of the ceiling fixtures and torchier shades create a calming cadence from one area to the other. The deft treatment of rectangular shapes of the wall material creates a subtle visual energy.•
Alitalia Airport Lounges Location: Milan and Rome, Italy Architect: Studio Marco Piva International air carrier Alitalia is experimenting with a new strategy to boost the number of passengers booking flights on its routes. The airline, dealing with falling revenues and stiff competition from cut-rate carriers, is luring upscale and frequent flyers, not with added airborne perks, but with groundlevel ultra-elegant airport customer lounges. At Rome’s Fiamicino and Milan’s Malpensa airports, Alitalia is promoting a new concept of a between or before flight stop-off destination as a personalized invitation to a handsomely appointed Italian residence. Retained to mix an Italian villa with contemporary corporate style was Italian starchitect Marco Piva, whose hospitality practice reads like a world-wide Who’s Who of hotels and dining venues.

For the Casa Alitalia lounges, as master designer for the interior plan, furniture, and lighting, Piva translated the client’s conceptual vision and also directed the myriad technical details. Fiamicino can accommodate 115 guests in 8,600-sq.-ft.; Malpensa is 5,400-sq.-ft. for 90 guests. Both facilities offer a live cooking area, buffet, bar, meeting rooms, a library, bathrooms with showers, and specialty areas. Piva interplayed two geometric themes—rectangles and variations of half cylinders— as the basis for a brand identity, also stated by orange and deep grey color tones. On the walls of the cloud-ceiling entrance are horizontal rectangular shapes separated by bands of light. In an informal meeting space, walls are covered by double band of similar shapes
placed vertically, while a more symmetrical composition appears in a larger area. Crystal half-cylinder fixtures suspended from a circular medallion provide controlled glitter. Piva’s design for a hanging fixture comprised of a white globular up-and-down lighting
element and a flared transparent outer shade appears in two versions. In the buffet area, they are smoke glass; above the bar, the outer shade is clear. Opaque glass shades for the torchiers restate the half-cylinder shade theme throughtout the space.

The Beer Boutique Location: Toronto, Ontario, Canada Interior and Lighting Design: II BY IV Design When the Liquor Control Board of Ontario (LCBO) decided to embark on a promotional campaign to encourage traffic for their beer distribution outlets, they expanded their selection of domestic and imported brews and adapted the successful retail strategy of slick new store interior. The initial site to test the theory is The Beer Boutique, a 3,000-sq.ft. building located in Toronto’s Liberty Village, in an historic neighborhood. The LCBO entrusted their vision to the mega-award winning Toronto firm II BY IV Design to execute a unique and urban interior. Drawing on their success as store planners and designers to Canada’s top luxury retailers, II BY IV created a product-enhancing layout the draws shoppers to and around the displays, encouraging a sense of discovery. Instead of
ordering off large signage that doubles as a price list in typical LCBO outlets, beer enthusiasts can check out the labels and bottles that are impressively presented on the shelves. Based on their understanding that today’s customers appreciate a sense of retailtheater along with a broad merchandise selection and responsive pricing, the designers placed a large wooden square platform fashioned from reclaimed wood as the central visual focal point. It is also used for tasting and pairing events as well as to display featured brands. From the dark painted exposed ceiling is hung a light sculpture with a profile that duplicates the platform’s outline. Light tubes are connected by interlocking copper tubing, a subtle reference to the traditional copper kettles used for beer brewing.

For 888 Boylston Street, which completes the Prudential Center’s development in the city’s Back Bay commercial sector, Boston Properties, Inc., commissioned architects FXFowle to design an office building that communicates a distinctive exterior image that carries into and accents the ground level lobby. Buro Happold served as both MEP engineers and lighting designers for the resultant 17-story, 433,000-sq.-ft. building. Sustainability in energy systems and energy use ranked high in the building program objectives that include a LEED platinum nomination. Rooftop wind turbines and a photovoltaic crown mark its presence on the
skyline. At the exterior plaza level, a cluster of illuminated poles are anemometers that change color to reflect wind speed and the power generated by the turbines above. Through full double-height glazing, lobby windows reveal a sweeping expanse of dark flooring punctuated by an extended illuminated reception station. Behind it is a vertically detailed backdrop marked by a single large-scale circular sculpture. To accent the visual drama of the reception area, a close-placed row of fixtures are beamed to the wall and the surface of the reception unit. Top-lit structural columns carry graphic imagery. Panels of vertical greenery bring the outdoors inside and soften the otherwise elegant minimalist aesthetic. Buro Happold’s lighting team introduced small, high-efficacy LEDs to produce a maximum horizontal 10 footcandle reading for the lobby, down from 30 fc in other Boston Property holdings.

The brief also called for the creation of spaces that facilitate development of skills essential for modern medical practice. The Solution: The exterior profile of the Vagelos Education Center is expressed as a series of 14 irregularly stacked glass enclosures that appear to be balanced on a plinth base. Sustainable features include fixed and operable shading that optimizes daylighting and solar gain by programmable areas. Green roof technologies reduce heat generated by the surrounding asphalt and concrete. A clean ceiling effect throughout the building was achieved by the lighting with a variety of beam options to illuminate spaces of varying heights, up to 30 ft.

‘LIGHT PAINTINGS’ GIVE CHARLOTTE’S ‘QUEEN’ TOWER A BRIGHT, NEW CROWN BANK OF AMERICA CORPORATE CENTER Charlotte, North Carolina
In an invitation they couldn’t refuse, New York City-based Focus Lighting was asked to redesign the exterior illumination of the Bank of America Corporate Center in Charlotte, N.C. Built in 1992, the building remains the tallest structure in the city, rising 871 ft. For the renovation, the firm produced a precise, multilayered solution that creates a stunning display of “light paintings” on the city’s skyline. Nicknamed the “Queen City,” Charlotte is proud of the tower, which is often referred to by locals as the “Queen’s crown.” As the building is a stellar feature of the city’s skyline, the redesign needed to respect the style of the original lighting, yet add panache. “The project was initially brought to us as a technology upgrade, explains principal lighting designer Brett Andersen. “But after analyzing the architecture, and its prominence on the skyline, we knew there was a bigger opportunity.” Prior to the redesign, he explains, the original lighting scheme used just a single layer of white metal halide lights at each level. The Focus team developed a guiding concept of light paintings’ for the crown. “Instead of picking seemingly random colors of light, each painting would be an artistic composition inspired by a source of Charlotte pride—like a beautiful Carolina sunrise, or their beloved Panthers NFL team,” says Andersen. The team knew it wanted to use LED technology to highlight Cesar Pelli’s iconic architecture, but it also recognized an opportunity for Bank of America to give a gift to the citizens of Charlotte. “This was a chance to create a memorable design

BANK OF AMERICA CORPORATE CENTER, Charlotte, North Carolina
THE CHALLENGE: Commissioned to redesign the exterior lighting for the Bank of America Corporate Center in Charlotte, North Carolina, Focus Lighting saw an opportunity to go beyond a technology upgrade, convincing the client to illuminate the building’s crown with beautiful compositions of color, or ‘Light Paintings.’ To create this vision, the team needed a low-cost LED fixture with superior color mixing and a tight, high-output beam. Also, because the building was publicly visible throughout the entire redesign, they had to change fixtures quickly to avoid areas of the building going dark at night. They also faced architectural challenges of working in tight spaces and around various obstructions on the roof. THE SOLUTION: To make their vision of creating a series of beautiful light paintings a reality, the team began by conducting several in-studio tests with different LED fixtures, then chose a smaller selection to test on the building. Once they decided on the best fixture, the lighting designers developed an adjustable base assembly that allowed for a seamless, undetectable transition from metal halide to LED. The base assemblies were installed around the existing fixtures, with power and data in j-boxes mounted to the bases. So, as one group of old metal halide fixtures was removed, new LED fixtures were installed in their place and powered on immediately to minimize the visual disruption. They also programmed the new LED floodlights to emulate the color of the existing metal halide lights and temporarily aimed them to look like the old lights.

CZECH WORKERS SAY ‘ANO’ TO LIGHTS THAT BOOST LIKE A STRONG CUP OF JOE INNOGY OFFICES Prague, Czech Republic
“Ano” in Czech means “yes”—and that’s exactly what office workers from a Prague-based energy company are saying about their approval for new, more biologically based LED lighting installed in their company headquarters. In November 2017, innogy completed a deep renovation of nearly 33,000-sq.-ft. of office space at its Czech Republic headquarters at Limuzská, Prague. The company went from a traditional closed office environment to open-plan and seized the opportunity to create a best-in-class work environment to enhance the comfort, wellbeing and productivity of its 550 office employees. Lighting played a key part of the renovation which involved a new restaurant, furniture, healthy food, kitchens and creativity spaces. Philips Lighting installed a networked lighting system consisting of approximately 2,000 Philips LED luminaires. These included 860 Philips PowerBalance tunable white ceiling fixtures and 96 Philips LuxSpace tunable white downlights—all programmed to provide different light settings at various times of the day. The subtle differences in the color temperature and intensity of the lighting also supports eye comfort and may be personalized by employees to suit specific tasks. While the emphasis of the lighting system is on enhancing employee comfort, it is also helping to improve operational efficiency through remote monitoring and maintenance. The system, according to Philips, is tuned to support the circadian rhythms of innogy’s office staff, and stimulates their energy levels at set times in the day. Employees enjoy a comfortable bright light, similar to natural daylight, to start

THE CHALLENGE: Upgrade a traditionally illuminated office into one that not only incorporated more modern LED lighting, but also took advantage of the technology’s other, more human-centric capabilities, that particularly might benefit employee productivity. THE SOLUTION: A state-of-the-art color-controllable LED system from Philips Lighting was installed that emits a brighter, higher temperature light in the morning, and again after lunch, to give employees an energy boost, similar to a cup of coffee. Nearly 80% of employees surveyed described the new lighting as better or much better than the previous fluorescent tube lighting, while 60% agreed that it contributed to a place in which they wanted to work.

Product Introductions
Low-Profile Engine DirectAC LED Engines from Fulham Co. are integrated onto the circuit board and support power ratings from 120V to 277V. Their low-profile design is well-suited for use in wall sconces and ceiling fixtures, and they can be used in both open and enclosed luminaires, with or without glass or plastic lenses. Visit www.fulham.com or Circle 291.
A recent DOE Snapshot report notes 63% of outdoor LED fixtures and kits meet output and efficacy specifications required for acceptance onto DLC’s Qualified Products List.
1 Brassy Personality The LQPL Path Light is one of three fixtures in Auroralight’s new Qube series. Featuring solidbrass construction, the lineup also shares a deep prismatic design enabling a uniform 120-degree distribution from a single lens. Visit www.auroralight.com or Circle 292.
2 Next-Generation Performance The second generation of Acclaim Lighting’s Dyna Drum HO high-power floodlight can be specified with a quad-color chip that enables a broad range of color mixing, including pastels and dynamic white, all in the same fixture. Visit www.acclaimlighting.com or Circle 293.
3 Showing Colors in Their Best Light D-series Special Color chip-on-board LED lighting packages from Samsung Electronics are tuned to deliver high color vividness, without using potentially harmful UV or near-UV chips.

Product Introductions
The Power of Touch Offering the same user-interface capabilities as its Tessera Controller, ETC’s new Mosaic Touchscreen gives users a full controller feature set, including full configurability, at a lower price point. Buttons, faders, color pickers and other controls all can be presented on the 4.3-in. screen. The unit is compatible with any Mosaic system running Mosaic software 2.4 or above. Visit www.etcconnect.com or Circle 295.
Dimming effects, such as dimto-dark and dim-to-warm, and individual dimming control, are desirable to aid “comfort” lighting for their positive emotional effect on occupants.
4 Cut the Wires Legrand’s new Wattstopper wireless networking approach brings together a border router and wireless network bridge that allow contractors to network digital lighting management rooms together wirelessly. Visit www.legrand.us or Circle 296.
5 Safety First Anti-slip glass treatment is available for recessed exterior fixtures from Griven. The treatment mixes ultra-fine sand particles into a special white varnish that’s mechanically silkscreened onto to the lens surface for a rough, opaque appearance. Visit www.griven.com or Circle 297.
6 Versatile Area Option The curvilinear Skyliner area luminaire from U.S. Architectural Lighting can be specified with any of nine distribution patterns and in several mounting configurations, with optional angled, concave or domed shades. The fixture incorporates a microreflector behind each LED to improve forward throw. Visit www.usaltg.com or Circle 298.

Product Introductions
Driving Greater Flexibility The Excite product series from Tridonic now features a new range of constant current, programmable LED drivers intended for use in linear, area and general-illumination luminaires. The 35W, 50W (shown here) and 75W drivers can be tuned to dimming curves specified by controls manufacturers and feature efficiency rates of up to 90%. Visit www.tridonic.com or Circle 299.
From their palette, lighting designers are applying illumination strokes that help to define time/place relationships, focus on customer experience, and branding.
1 Big Variety, Small Package The Silo 2020 LED Track/Rail Luminaire packs the capability for a wide range of dynamic beam adjustments into a small, unobtrusive package. It’s one of three WAC Lighting products to win top honors in the 2017 Lighting for Tomorrow awards. Visit www.waclighting.com or Circle 300.
2 Budget Friendly The Entra 3-inch adjustable downlight joins Tech Lighting’s Element line as a cost-effective option for residential and commercial applications. Specifiers can choose from a range of options, including housings for either new construction or remodeling installation and round or square apertures. Visit www.element-lighting.com or Circle 301.
3 A Sunny—and Safe—Disposition SunLike Series LEDs from Seoul Semiconductor, which produce illumination intended to match the spectrum of natural daylight, now have an RG-1 Eye Safety certification, indicating no photobiological risk, following testing according to International Commission on Illumination Standard IEC/EN 62471.

Product Introductions
Warmer Alternative Access Fixtures has added a 3000K color-temperature option to a number of its bollard product families, for applications where warmer-toned lighting is desired. The fixtures also can be ordered with 4000K and 5000K light sources. Shown here is the Vand bollard, which showcases a lens-free design that’s still tough enough to stand up to dust and weather. Visit www.accessfixtures.com or Circle 303.
Designing within the parameters of the WELL Building Standard requires a significant investment in time to calculate and simulate target environments.
4 It’s Got Moves Zumtobel developed its Cardan Evolution downlight with the German architecture firm Blocher Partners. The fixture can turn and twist thanks to its gimbalbased “cardanic” design—but unlike many such luminaires, illumination is kept out of the fixture, itself, at tilt angles of up to 20 degrees. Visit www.zumtobel.com or Circle 304.
5 High-Efficiency Leader With efficacy ratings that reach as high as 167 lumens/watt, Eco-Series retrofit troffer fixtures from Illumisoft Lighting have captured the top four spots in the DesignLights Consortium’s efficiency ratings. Using patented, high-efficiency optical films, the fixtures offer energy savings of up to 50% over standard LED replacement tubes. Visit www.illumisoftlighting.com or Circle 305.
6 Get More Color Specifically engineered for color mixing, the Luxeon C Color LED family from Lumileds now boasts significantly higher lumen output; Red-Orange output has been boosted by 12% and Red units by 8%. Visit www.lumileds.com or Circle 306.
