Cree beats LED efficiency benchmark
January 24, 2014 // Paul Buckley
Cree, Inc. is claiming to have raised the performance bar with the demonstration of the first 200-lumen-per-watt (LPW) LED concept luminaire, which is more than twice the efficiency of the best linear fluorescent luminaires.
The latest Department of Energy (DoE) projections had estimated that this level of luminaire efficiency would not occur until after 2020.
The 3,200-lumen concept luminaire delivered greater than 200 LPW at 80 CRI at thermal equilibrium while remaining within the ANSI color specification for 3000 K. The innovations behind the concept luminaire will enable Cree to deliver increased performance in LED luminaire applications at a lower cost to accelerate LED adoption.
“Demonstrating the industry’s first 200-lumen-per-watt luminaire once again illustrates Cree’s leadership in LED lighting,” said Norbert Hiller, Cree executive vice president, lighting. “The innovation required to achieve this record performance will usher in a new era of increased performance, quality and affordability for our LED lighting customers.”
