Cree Sets New Efficiency Benchmark with First 200 lpw LED Luminaire Prototype

Cree, Inc. raises the performance bar again 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, but Cree’s latest innovation has made this possible six years sooner than projected. The prototype leverages Cree’s vertical integration with innovations in LED chips, optics, materials technology and novel system design to deliver unprecedented performance.

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 3000K. 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.”
