Cree R&D result breaks 200LM/W barrier

04 Feb 2010

High-power LED manufacturer Cree claims to have set a new laboratory record for a white, high-power LED of 208 lm/W. Just two months ago, Cree reported an R&D result of 186 lm/W.

The 208 lm/W LED produced 208 lumens of light output at a correlated color temperature of 4579 K. The tests were conducted under standard LED test conditions at a drive current of 350 mA at room temperature.

As acknowledged in Cree's press release, this level of performance is not yet available in Cree's production LEDs. The company says that this R&D result passes a "significant milestone" within the solid-state lighting industry, as well as demonstrating Cree's "relentless drive" to increase the performance of its LEDs.
