[h=1]Cree Reaches LED Industry Milestone with 200 Lumen-Per-Watt LED[/h] New XLamp MK-R LEDs Deliver Record-Breaking Efficacy and Next-Generation Price-Performance for LED Arrays
DURHAM, NC -- Two years after breaking the 200 lumens-per-watt (LPW) R&D efficacy barrier, Cree, Inc. (Nasdaq: CREE) delivers another industry first with the introduction of the Cree XLamp® MK-R LEDs. The new MK-R LEDs leverage the SC³ Technology™ next-generation LED platform to deliver up to 200 lumens-per-watt (at 1 W, 25°C) LEDs.
How long until these MK-Rs or something like them are in flashlights and/or dedicated cycling lights?
