ABOVE: Excluding one product with very high efficacy (91 lm/watt), the Series 16 products had luminous efficacies between 51 and 65 lm/watt. This is favorable compared to other light source types commonly used in directional lamps, and should continue to rise.

ABOVE: Performance criteria include initial output, total input power, luminous efficacy, power factor, color rendering index, special color rendering index (R9) and correlated color temperature.

Round 16 of DOE’s latest CALiPER testing focuses on directional BR30 and R30 Edison-base LED lamp retrofits. While this is a smaller category than the PAR lamp target, the use of the R and BR lamp is widespread in residential and cost-sensitive commercial spaces. The lamps tested are direct replacements for inefficient incandescent and CFL reflector lamp products, where energy savings is the primary value added. The report reveals several significant issues, most notably the disconnect between some LED products entering the market and market reality. In this case, while the LED products do duplicate the light output, and deliver energy savings, their high cost misses the mark for customers who choose “R” and “BR” lamps mainly due to their price. While some may purchase the lamps due to interest in LEDs, there are numerous “PAR” retrofit products that will perform better at the same or lower initial cost. As far as testing results, for clarity, rather than lumping all directional sources into a single category, it is best considered when divided into two sub-categories: Semi-directional—products without focusing optics; and Focused-directional— products that produce a distinct directional emission. The former include “R,” “ER” and “BR” lamps. The original form of these lamps utilizes internal silvering and a blown-glass envelope to produce hemispherical distributions. This classification now includes CFL reflector lamps. Focused directional sources, identified as “MR” and “PAR” lamp forms, use molded-glass reflectors with specular aluminized coating and glass lenses to produce high center beam energy and greater control. Round 16 focused exclusively on the LED products targeted as replacements to the lower performing BR30 and R30 semi-directional lamps. The application of these lamps includes recessed down-lighting,

directional display and accent lighting. as the overly broad light distribution is cut off by baffles and fixture bodies. Lacking a center beam focus, these lamps are frequently low performing in application. Cost Considerations A key consideration in R and BR lamps is that they are primarily chosen for first-cost over performance. The LED versions tested in Round 16 range in price from $35 to $104 (mean $55.39), opposed to the incumbent incandescent lamp cost of $2.80, or a CFL BR30 cost of $9.90. This raises the question of whether these products will be accepted in the highly cost-sensitive target market they are designed to satisfy. The lamps tested consumed between 6 and 14.3 watts, with a mean efficacy of 59 lm. per watt—only slightly better than the CFL replacement benchmarks which tested at 39-51 lm. per watt. In comparing the CFL to an LED R or BR lamp with identical optical distribution, there is little to support the premium cost of the LED products in this category. Six of the 13 LED lamps tested produced distributions virtually identical to the CFL replacement it was being benchmarked against, while only one came near the slightly narrower incandescent benchmark. This seems at odds with the application of the inherently directional LED light source, which is erased by use of diffusers, which destroys any justification of their high price premium beyond potentially longer service life. Photometric Performance Ultimately, how well a lamp performs in application falls on its photometric performance. In this case, the majority of the tested LED replacements were apparently designed under the assumption that the CFL replacement R lamp was the desired target—which appears to be designed to replace the 65-watt BR lamp. However, four of the LED replacements delivered greater optical control with slightly narrower beam patterns and moderately improved field angle control. Compared to the other lamps, these products would produce improved performance in enclosed fixture designs, representing a composite improvement in fixture efficiency. However, for the same price, a PAR30 LED replacement product with even greater optical control and directional energy could be obtained that will outperform all of the lamps tested in application. Round 16 illustrates the disconnect that exists between some LED products entering the market and actual market reality. In this case, while the LED products do duplicate the light output, and deliver energy savings, their high cost misses the mark for customers who choose “R” and “BR” lamps mainly due to their price. While some may purchase the lamps due to interest in LEDs, there are numerous “PAR” retrofit products that will perform better at the same or lower initial cost. For this reason, one must question the need for this class of LED replacement lamps altogether.•

Look to the Clouds Designed as an interactive art installation, “Cloudscape” helped entertain visitors at Sydney, Australia’s fourth annual Vivid Sydney arts festival this past spring. Combining a grid-based structure with a dazzling display of Mylar balloons and LED lighting arrays from Traxon Technologies, Cloudscape also served as a popular meeting place. Designers connected the company’s flexible Dot XL and String RGB products to motion sensors to produce light shows that grew in intensity with the crowd’s movements below. The result was described as a “storm” of light by designers Nicolas Thiolouse and Kim Nguyen-Ngoc, from the Sydney architectural firm Woods Bagot.•

PUBLIC BUILDINGS: HART SENATE OFFICE BUILDING / AMERICAN GRILL

LEDs Go To Washington A new budget-cutting measure passed the Senate earlier this year without requiring a single vote when 150 new LED fixtures were installed throughout the Hart Senate Office Building. The project involved replacing CFL downlights and linear fluorescent fixtures with CR22 architectural troffers from Cree. The new luminaires were installed in the building’s American Grill, sundry shop and main hallway, and should reduce related energy demand by 33%. Plus, the LEDs’ extended life should also help reduce maintenance requirements.•

luminance volume has dropped significantly. Roadway and area luminaires once employing hundreds of LEDs are giving way to newer approaches using less a fraction of that number. The result is more compact designs and lower luminaire costs. High intensity sources also increase optical efficiency. However, the downside to brighter LEDs is potential for glare, and eye damaging intensity. IEC Standards 62471-2006 and ANSI/IES RP-27 have evolved to address this issue directly, with test procedures and exposure limits defined, including blue light emission associated with white LED sources.

Use More Low and Mid Power, Lower Cost LEDs per Luminaire The improvement in LED efficacy applies to products at all energy levels. This has given rise to products utilizing low and mid-power LEDs in tightly spaced arrays to deliver more uniform luminous presence. This is made possible by the low cost of the lesser LEDs. The end result is the potential to create luminous surfaces without vis-

The Forces Of Retail The global economy is a force moving retailers and wholesalers to expand scope and reach to increase market share, revenue and customer base. Investment in employees, product design, new store openings, and marketing are paying off for retailers who are expanding their international presence in order to become less dependent upon a local, regional or national economy. That said, the U.S. is still considered a mecca for retailers seeking an international presence in a stable marketplace. Advances in technology are another force transforming retailing itself as well as the shopping experience. Responding to increasing customer demands, retailers are giving local, national and global customers access to merchandise, service, and product information, tailored to their requests. Many retailers and wholesalers are also being smarter about their real estate, opening smaller stores, minimizing their footprint while increasing their sales-to-square foot ratio. Designers and manufacturers with a desire to tell their own brand story and influence the customer experience are increasingly becoming retailers, creating an upscale environment for their luxury and aspirational products. These significant trends, growing in momentum in the U.S. and internationally, are the drivers that signify that retail is undergoing global transformation, prompting predictions that within five years the current business model will be nearly unrecognizable. —By Patti W.

To light the coves, lighting designer Emily Monato of Cooley Monato Studio, New York, used LEDs for their long life and calibrated beam angles. Retail store design veteran David Dalziel of London-based Dalziel and Pow has been involved with lighting Primark stores for more than 20 years. For the renovation of the four-level, 100,000-sq.-ft.

Coeur d’Alene Tribal Resort Expansion

Innovation in Idaho

Owners: Coeur d’Alene Tribe Architects: Mithun, Seattle Lighting Designer: Dark | Light Design, Seattle LED product manufacturers: Erco, Hydrel, Boca Flasher, Architectural Area Lighting, Color Kinetics, Lightwild, Lumenpulse, BK LIghting, Winona. Text: Ellen Lampert-Gréaux Photos: Jill Cody The Challenge: Like many older gaming facilities, the Coeur d’Alene Tribal Resort, located near the town of Worley in the northern portion of the Idaho panhandle, was in need of expansion. The casino’s management was faced with the task of adding something new in order to compete as a true destination, with attractions for non-gamers, and to increase its overall appeal. The goal of the tribe was to create a complete resort experience, integrating elements and symbols of their tribal culture and beautiful natural landscape with modern design trends and lighting technology. The challenge, therefore, was to create a dramatic new facility with improved amenities while respecting the tribe’s concern about their impact on the environment. The Solution: The result is a 110,000-sq.-ft, LEED Gold-certified addition comprised of 100 four-star guest rooms, two restaurants, a lounge, a spa, and the “skycatcher,” a circulation element that connects the new elements of the complex with the existing gaming space and provides a gathering space with sweeping views of the rolling hills of the Idaho landscape.

The Night Sky Lounge is actually an acrylic wall backlit with LED pucks placed at random to reflect a starry sky. A DMX program changes the pattern over a one-hour loop.

Vision Quest When it came to approaching how to illuminate the expansion and renovation of the Coeur d’Alene resort, which included an existing casino, lighting designer Jill Cody had a specific vision: It would not be Las Vegas-style glitz, rather, she wanted to integrate the lighting as an additional layer to help tell the tribal story and enhance the warmth usually associated with hospitality settings in a way that harmonized with the rustic elegance of

the materials used. “This meant the careful illumination of materials and surfaces, the creation of contrast to enhance the mood, and respect and reference to tribal culture and tradition,” says Cody. Since the resort sits 30 miles outside of the eponymous northern Idaho town, there is no light pollution in the night skies, allowing lighting to subtly create the resort’s environment. “We were trying to create an exciting environment, yet not

overwhelm the darkness. We did not light the exteriors of the buildings, but went for subtle light from the interior rather than Las Vegas-style sparkle,” says the designer. For example, bridging the old building to the new is a courtyard dubbed the Night Sky Lounge (above). To spice it up, a blue acrylic wall, that masks a wall on the old building, is backlit with LED puck lights placed randomly for the effect of a starlit night with softly twinkling stars. A

slowly changing DMX program creates the variable star pattern over a one-hour programed loop. Lumen Pulse linear LED visually ground the blue wall, along with BK custom MR16 downlights on cables, selected for their dimming capability. Cody says the blue recalls the night sky above, and contrasts with warm incandescent illumination that extends the fire-like glow. “The first time I saw the blue wall I had a verklempt moment, it was so beautiful,” admits Cody.

“It makes you feel as if you are doing this for a reason, and makes it amazingly meaningful. You feel connected to your work as a lighting designer at the end of a very long project.” Color Correction Color changing was also a big part of the project as Cody wanted to match up with architect Mithun’s choice of building materials, which she says has rural overtones, with an emphasis on wood, water and stone, plus

blackened and pre-rusted steel. “It is a very Northwestern materials palette,” explains Cody, who wanted to make sure the materials got their due through the lighting. She decided LED RGB was the appropriate medium for story telling. “We used color-changing for three major design elements: Eagle Staff Tower, the Feather Bench, and the Skycatcher floor. Color sequences were created with references to tribal culture, such as costumes, the night sky,

and Lake Coeur d’Alene, itself, the tribe’s ancestral home. These three color-changing elements are coordinated with one another and run on a schedule that tells a different story each night of the week,” notes Cody. The elements are coordinated with the same color at the same time, which according to Cody, took complex programming to achieve, with different palettes to evoke different tribal references, from the color of their costumes to a rainbow effect.

ARCHITECTURAL SSL • 11.12 • 29


Eagle Staff Tower One of the most visible tribalinspired elements is Eagle Staff Tower, a 105-ft.-tall iconic column of Corten pre-rusted steel with slots, or lens-covered openings, that allow the colorchanging light to shine through as a welcome beacon at night (its base is visible in the upper right background of the image to the right). Each slot can be a different color via signage-grade LEDs. Red beads that adorn the tower are lit from wells in the ground. The Water Feature Approaching the entry to the resort, a winding, luminous resin water feature guides guests to the resort’s front door. Linear LED fixtures backlight the resin and highlight a Corten steel wall that runs behind the water. “The tribe used to have land on Lake Coeur d’Alene, and water is very important to them,” says Cody. “The line of light on the water feature points to the lake.” In fact, the light shines through a transparent blue resin material, using Hydrel fixtures. The water is also lit from the front as well with Boca Flasher linear submersible LED fixtures that reveal the movement of the water. The light on the water feature is all white; as Cody points out, “because the resin is blue, there is no reason to change colors on it. I really like the blue against the rusted color of the Corten steel.” The Steakhouse In the new restaurant, The Steakhouse, Cody used LED fixtures where appropriate, as well as dimmed incandescent lamps to meet a one-footcandle light level. “The color quality of the light was really important with all the wood in the space,” notes Cody, who used MR16 downlights on low-voltage tracks in the ceil-

Natural colors and elements, including wood, were also important components within the project. In the facility’s new restaurant, The Steakhouse, lighting designer Jill Cody noted there was a particular emphasis to get the coloration of the wood right in the dining establishment.

ing. During the day, a large glass wall allows a lot of natural light to enter the space, and low light levels near the glass minimize reflections and allow a clear view to native plantings outside. “There is a different quality to the light during the day,” Cody adds, noting that the lighting in the restaurant is actually bumped up during the day to make sure the back corner of the room seems brighter, and to balance the room. She also used Winona linear LED kick-lights and LumenPulse cove lighting to add accents to the wood ceiling.

MATCH ON ACTION

In the entry there is also an art installation with abstract timelapse photos of tribal members in traditional costumes. The images are on laminated glass with a sandwiched film layer. “The idea was to take tribal stories and weave them into the project in unique ways,” says Cody. “It was a real education for the design team; we learned a lot about the tribe and their history.” Colored LED was employed in the floor to evoke the legend of “Coyote Scratches” and match up with the colors in the art feature.

The Casino Entry The theme of color-changing light continues at the casino entry, creating a transition zone between the bright, day-lit area of the “skycatcher “and the much darker gaming floor. In the “skycatcher”area (below, left), a blend ceramic metal halide uplight and downlight creates quiet gathering zones to balance a more active circulation zone. Uplights and downlights are turned off during the day in this well-daylit space. But in this space, LED comes alive in communicating another tribal reference: the legend of “Coyote Scratches” in the landscape, which are evoked in the space with glowing LED tiles (Lightwild) that reach out into the “skycatcher” to hint at the excitement inside the casino. “We wanted to tell people that something existed back there,” says Cody.

ARCHITECTURAL SSL • 11.12 • 31


CONNECTED TO THE LAND  The tribe carries a deep connection to the land and the resort site sits at the confluence of two habitat types: grassy hills and a forest. As a result, exterior views were important to the architecture. Low light levels near the glass minimize reflections and interior lighting is warm and quiet to impart an ambiance of reflection and healing.

In the entry there is also an art installation with abstract time-lapse photos of tribal members in traditional costumes. The images are on laminated glass with a sandwiched film layer. “The idea was to take tribal stories and weave them into the project in unique ways. It was a real education for the design team; we learned a lot about the tribe and their history,” Cody notes. The Spa Adding to the allure of the resort is a spa where the design is defined by a large stone wall, uplit with incandescent sources, which Cody selected for “good dimming control,” although she adds it is “unusual” to use incandescent on a project at this scale these days. The downlighting is a mix of MR16 and fluorescent. “We started designing this project in 2009. There is a wider choice of LED fixtures to choose from today, but I’m not sure we could have afforded them for almost 1,000 downlights on this project. The spa also features a glass panel that sits atop the stone wall, allowing light to splash into the adjoining pool, once again emphasizing the importance of daylighting in this project. The Courtyards Beyond the centerpiece blue wall, another signature design element in one of the outdoor courtyards is a wooden bench

The bench features a center spine of Corten steel, echoing the materials palette used elsewhere. Color-changing Philips Color Kinetics EW Powercore LEDs under the the feather bench give it the appearance of floating on a cloud of light. “The bench is designed like an eagle feather, another important element of tribal culture,” says Cody. “The Corten center of the feather is illuminated with linear Lightwild white light that does not change.“ All colored light at the bench changes at the same time, so the experience is different from the tower and Skycatcher, where multiple colors are visible at a given time. “Instead, the sequence of color takes place over time,” says Cody.•

TRIPLE AXEL LANDED: SUSTAINABILITY AT A REASONABLE COST & IMPROVED LIGHTING ERNST & YOUNG OFFICES New York City

The professional services firm of Ernst & Young believes in corporate sustainability. In fact, the organization hopes to have half it’s employees in LEED-certified spaces by 2013. But being accountants, they want to make sure any such measures reflect financial soundness. A recent, significantly LED lighting retrofit of the company’s Manhattan offices proved a fruitful marriage of both goals—oh with a third benefit of greatly improving the lighting environment. As part of their sustainability initiatives, the company regularly consults energy specialist Jim Schwartz of JAS Consulting to keep tabs on their buildings with an eye toward better efficiencies where and when possible. In the course of such due diligence, about three years ago, Schwartz had a casual conversation about the company’s Times Square offices with lighting designer Stephen Margulies of One Lux Studio. As Ernst & Young was preparing to enter a new lease on the space they wished to evaluate a few things, particularly lighting. Following a walkthrough of the 32 floors of offices, Schwartz knew “instantly” that “millions of watts” could be pulled out of the space. That being said, the consultants also wished to be sensitive to the original lighting design created by Gensler and Susan Brady, which was done about 10 years prior. At the time, the emphasis on the lighting design was more on the aesthetic, according to Margulies, and the design was indeed “fantastic,” but not so efficient from an energy perspective.

ABOVE: The retrofit dropped wattage consumed by about 40 watts per sq. ft., which cut the office’s total lighting consumption in half. Between energy savings and maintenance savings, the company will save about $1 million annually. A mix of sources were employed, almost a quarter of those being LED. “We didn’t set out to do an LED retrofit, it just evolved that way,” says Lighting designer Stephen Margulies of One Lux Studio.

“There were lots of MR-16s and lots of maintenance issues,” says the lighting designer. Not only were there a lot of inefficient sources—many with old ballasts—but the offices were generally overlit. In some places they found

THE CHALLENGE: Pull as many watts as feasible out of the client’s 650,000-sq.-ft., nearly 6,000-employee office space while preserving as much of the space’s original lighting design as possible.

THE SOLUTION: Three strategies were emploed: • More efficient retrofit lamp sources were installed where possible—notably among the existing MR16 and CFL lamps • As many existing fixture/luminaires were retained as possible, but refit with more efficient light source components • Replace fixtures where necessary to accommodate more efficient sources As a result, the design cut lighting consumption in half from its whopping original 6.2 million kWh per year, simultaneously reducing CO2 emissions by roughly 2 million pounds.

thinking this was more than a light bulb change,”

SMOOTH TRANSITION The new lighting system reduces annual lighting energy consumption by 54%. More than 3,000 high-wattage CFLs and MR16s were replaced with 20-watt LEDs. Elsewhere, existing fixtures were refit with LED components for greater efficiency. In all, the lighting consultants “touched” nearly 20,000 fixtures—a fourth of that with LED solutions.

SSLProfile: DIAPHANOUS CASINO CHANDELIER A DYNAMIC, YET ELEGANT VEGAS ICON CHANDELIER BAR Cosmopolitan Hotel, Las Vegas

Swinging from the magnificent light structure that gives its name to the Cosmopolitan Hotel’s Chandelier Bar is not an option, but guests can actually walk through the 44-ft. high and 75-ft. wide objet ’d’art. A winner of Cooper’s Source Award earlier this year, the spectacularly illuminated structure resides, where else, but in the Land of Lights, Las Vegas, where the bar’s draw is an experience that bathes guests in crystallized light. Upon entering the hotel’s casino, opulent strands of crystals drip dramatically from the ceiling; their luxurious luster beckons gamblers to pay a visit to one of the five bars and lounges that are seemingly suspended inside the crystalline strands. The lighting design team from New Yorkbased Focus Lighting, along with architect the Rockwell Group, created the unmistakable illusion of a single internally lit chandelier, and supplements it with lighting techniques to achieve sparkle in every delicate strand. With technical expertise and a larger-than-life mockup, the team deliberately aimed light at each of the kinetic chandelier’s seven million crystals. Their research helped to predict the precise angle at which each crystal would need to be illuminated to achieve the maximum sparkle with minimum headaches—that is, provide a dramatic display that is neither nauseating nor glaring to the casino’s guests. Being nearly 50-ft. high, the chandelier is surrounded by a concourse or casino circulation on two levels. It also contains five separate bars and lounges that seem to hover within the ethereal space.

ABOVE: The chandelier’s form offers a unique canvas on which to play with color washes and video projections. More than 200 RGB LED accents line the edge of the cantilevered floor slab, grazing both up the crystals and in an additional layer of vinyl-coated aircraft cord used as a semi-transparent projection screen.

The fixtures are available in natural wood, or in either white or gray enamel finishes. Visit www.leucosusa.com or Circle 299.

In SSL products today, there remains a persistence to apply the technology within a myopic focus on retrofitting through the Edison socket inventory. This dilutes the visibility of the technology and creates the assumption that the conventional is more desirable to all new alternatives where SSL can shine as a superior choice.

1 Indoor/Outdoor Solution The low-profile Lumiere Eon line from Cooper features illumination in three distinct beam patterns: forward, lateral throw and flood. Fixtures are available in aluminum, bronze, brass, copper, stainless steel and powder-coated aluminum. Visit www.cooperlighting.com or Circle 301.

LETTERS TO THE EDITOR:

EDITORIAL PREVIEW:

RGB OVER THE EDGE, BUT DOESN’T HAVE TO BE

IN THE JANUARY ISSUE: We take a look at how SSL is being applied in office environments as general ambient lighting. We’ll stick with our focus on interiors, with a profile on lobby/atrium of the Kansas City Marriott by Bruce Yarnell. Kevin Willmorth addresses proprietary controls issues associated with dimming LED. On the project front, we’ll showcase cool white lighting using exotic fixtures in the Sagafredo Cafe In Greenwich Village, New York. Across the Atlantic, we go inside a storage tank for a truly inspirational retrofit and re-use project. Also, new products, and of course, news.

Just read your LED Insights [from the September issue] and can’t agree more. RGB, since becoming “leading edge,” has gone to “over the edge” in usage. It is often just plain misused in too many applications.  That said, we are presently involved in using color changeable LED in a major residential pool and grotto system.  In carefully mixing white, and control of the RGB, we, hopefully, will create pools with beautiful effects presently not known. The waterfalls are intentionally always left white so that there is no chance that owners can turn the “scene” into visual chaos.  I am excited to see intense red water with white falls and white star effects randomly placed in the bottom of the lazy river along with fiber optic delivered LED white lights randomly placed in the ceiling of a rough stone ceiling.  Rather than being a “starry sky,” they are to emulate the tiny eyes of unknown underground creatures. So, RGB, if planned well, can be good. BRUCE YARNELL Yarnell Assocs., Shawnee, Kan.
