Cree hits 303 lumens per watt in LED demonstration unit

Cree Inc., Durham, N.C., announced that it recently hit a major LED milestone with the demonstration of 303 lumens per watt from a white high-power LED. This result surpasses Cree’s previous R&D industry best of 276 lumens per watt announced just over a year ago. “Achieving this level of LED efficacy amplifies the potential for the solid-state lighting industry to deliver smaller, lower-cost lighting solutions, and even larger-than-expected energy savings,” said Steven DenBaars, professor and co-director, Solid State Lighting and Energy Center, University of California, Santa Barbara.
