Cree demonstrates first 200 lumen-per-watt LED luminaire

LED chip, lamp and lighting maker Cree Inc of Durham, NC, USA has demonstrated what it claims is the first 200 lumen-per-watt (LPW) LED concept luminaire (more than twice the efficiency of the best linear fluorescent luminaires).

The latest US Department of Energy projections (according to the DoE Solid State Lighting Research and Development Multi-Year Program Plan, 2013) had estimated that this level of luminaire efficiency would not occur until after 2020, but Cree says that its latest innovation has made this possible six years sooner than projected. The prototype leverages Cree’s vertical integration via innovations in LED chips, optics, materials technology and novel system design.

The 3200 lumen concept luminaire delivered greater than 200LPW at 80 CRI (color rendering index) at thermal equilibrium while remaining within the ANSI color specification for 3000K. Cree reckons that the innovations behind the concept luminaire will enable the firm 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,” says 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.”
