ABOVE: The performance range was similar to LED Lighting Facts, and in general, the LED lamps had higher efficacy than both incandescent and CFL BR30/R30 lamps. The lumen output has increased over time; many lamps now match the lumen output of 65- or 75-watt incandescent BR30/R30 lamps.

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-
