Luminus Devices, Inc. based in Sunnyvale, California USA, released its third proprietary spectral technology, PerfectWhite™, which closely replicates the visual characteristics of halogen lamps (3000K). Halogen is considered by many in the lighting industry to be the gold standard in light quality among artificial lights.
The company asserts that its PerfectWhite spectral technology does not just replicate the output of halogen lamps, but improves upon it. Luminus says it filled the cyan gap and that PerfectWhite’s color point is slightly below the black body locus. As a result, Luminus says that PerfectWhite does not have the green/yellow tint that is common to halogen. Also, perfect white does not include ultraviolet radiation. The company reports that it was able to confirm designer’s preference for the PerfectWhite in testing at both Light+Building and Lightfair.
“The spectral characteristics of light from a halogen lamp are what make it so appealing, particularly in hospitality and museum applications,” said Tom Jory, VP of Illumination at Luminus. “Unlike other full spectrum LEDs that emit harmful near-UV radiation, PerfectWhite delivers the visual effect of a halogen lamp by filling the cyan gap that exists in traditional LED technology.”
PerfectWhite Adds to Luminus’ Portfolio of Unique LED Spectrums
The company’ PerfectWhite spectral technology adds to Luminus’ portfolio of unique LED spectrums including AccuWhite™ and Sensus™ spectral technologies that Luminus can apply to virtually any of the company’s COB LEDs.
The company spectrally engineered AccuWhite to maximize CRI performance, guarantying a CRI minimum of 95 and a typical CRI of 98. Notably, lighting designers and visual display managers continue seeking the very highest CRI and TM-30-15 ratings for interior lighting applications. AccuWhite LEDs boast TM-30-15 values as high as 95 for Rf(fidelity) and 100 for Rg(gamut), while achieving efficacy as high as 125 lumens per watt at a case temperature of 85°C.
Sensus™ spectral technology, on the other hand, addresses the needs of retails shops to inspire consumers with light that produces environments where whites are whiter, and saturated colors like blue and red are richer and more vibrant. Sensus’ engineered spectrums in 3000K and 3500K deliver a gamut area index (GAI BB15) as high as 120 and chromaticity below the black body curve, thereby allowing perception of pure, bright whites and deeper colors with increased contrast. Luminus asserts that while other LEDs might also produce pure whites, Luminus’ Sensus achieves pure whites without sacrificing efficacy which can reach up to 148 lumens per watt (LPW) at 85°C.
“Our three spectral technologies serve as the foundation for additional spectral tuning that is specifically targeted at human centric lighting,” said Jory. “Though there’s much still to be discovered, we are already working with industry partners to provide light that serves dual purposes of illuminating beautifully so people can see well and being healthy for people so they also feel great.”
