Cree sets R&D record with 254lm/W power LED

LED chip, lamp and lighting fixture maker Cree Inc of Durham, NC, USA has reported an R&D-stage white power LED with luminous efficacy of 254 lumen per watt, exceeding Cree’s previous industry record of 231lm/W.

The record R&D result has been enabled by elements of Cree’s SCĀ³ Technology Platform, available commercially now in the firm’s XLamp LEDs. Built on Cree’s silicon carbide (SiC) technology, the platform features advances in LED chip architecture and phosphor, as well as a new package design.

Cree says that the LED’s efficacy was measured at 254lm/W at a correlated color temperature (CCT) of 4408K, using standard room-temperature, 350mA testing.

“The core of the Cree R&D culture is a relentless focus on innovation that ultimately drives LED adoption,” says John Edmond, Cree co-founder & director of advanced optoelectronics. “Higher-performance LEDs can enable new and better LED-based applications and drive down the solution cost of LED designs.”
