Cree has released the XLamp® eTone™ LEDs, a new set of chip-on-board (COB) LEDs that delivers 90 color rendering index (CRI) light quality with the same efficacy as the standard 80 CRI LEDs.

In comparison with other COB LEDs of the same size and color, Cree’s new eTone COB LEDs feature the highest efficacy available in the industry with up to 155 lumens per watt (LPW) at 3000K CCT, 85°C. The enhanced performance of these new LEDs can radically transform the output, efficacy and size of LED luminaires to meet the needs of various applications.

Dave Emerson, LEDs executive vice president and general manager at Cree, said, “Two years ago, Cree achieved an LED industry first with our lab demonstration of a single high-power LED that hit an extraordinary 134 LPW at 1,587 lumens, 85°C and 90 CRI. Cree is committed to turning our industry-first R&D results into viable commercial products that offer customer-ready LED solutions where others do not. Today’s release of our eTone™ LEDs that deliver 90 CRI at the same efficacy as 80 CRI means that lighting manufacturers no longer have to sacrifice top-tier efficacy to achieve excellent color quality for indoor lighting applications.”
