Luminus Devices Inc of Sunnyvale, CA, USA – which designs and makes LEDs and solid-state technology (SST) light sources for illumination markets – has announced the immediate availability of the LUX COB series of LEDs.
The new COBs are available with a minimum color-rendering index (CRI) of both 90 and 95 and light-emitting surface (LES) sizes from 4mm to 22mm in a variety of flux densities and a full range of correlated color temperatures (CCTs). The 90 CRI minimum delivers high-quality light with the lumen/watt efficacy of an 80 CRI source, enabling luminaire makers to reduce SKUs by eliminating the need for 80 CRI products. Both the 90 and 95 CRI minimum versions use narrow-band red phosphor (current KSF) technology to deliver what is claimed to be outstanding performance and quality of light for a variety of lighting applications including retail, residential, hospitality, architectural, museum, downlights, track lights and spotlights.
“The LUX COB series is an exciting addition to the Luminus COB portfolio as they are available in not only 90 CRI minimum but we went a step further to offer an optional 97 CRI typical, 95 CRI min, with efficacy similar to what our competitors’ 80 CRI COBs have been delivering in recent years,” says COB product line director Dave Davito. “For example, the LUX 95 CRI min CLM-22 provides 157 lumens/W and the 90 CRI version reaches an amazing 176 lumens/W,” he adds. “Luminaire makers who received prototype samples have already been loading orders on us faster than any new product in our 10-year COB history.”
Luminus says that lighting designers are specifying it in projects where their end-users are most discerning and demanding, such as retail lighting, museums, hospitality and high-end residential. The launch of the LUX COB series further solidifies Luminus’ position without having to sacrifice efficacy. European customers in particular are planning to leverage the LUX COBs to help their end-customers qualify for energy-efficiency rebates, which require the entire fixture system (including optics and drivers) to achieve 120 lumens/W.
