Cree Inc. has been said to push the boundaries of LED performance as the first company to surpass the 300LPW efficacy barrier.

With its white, high-power LED, the company achieved 303LPW efficacy at a correlated colour temperature of 5150K and 350mA using a standard room temperature.

This landmark result tops Cree's previous R&D achievement of 276LPW about 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 ('re'?), University of California, Santa Barbara.

"Relentless innovation is a driving force at Cree as we continue the pursuit of 100 per cent LED adoption," said John Edmond, Cree co-founder and director of advanced optoelectronics.

"Pushing the boundaries of LED performance is critical to enhancing LED lighting designs, and this 303 lumens-per-watt result will enable more cost-effective lighting solutions," added Edmond.
