By Alyssa Dalton
June 17, 2014 – Cree says it has developed a demonstration of the first 200 lumen-per-watt (LPW) LED concept luminaire; an achievement that, according to Cree, the U.S. Department of Energy (DoE) projected would not occur until after 2020.
According to the company, the 3200 lumen concept luminaire delivered greater than 200 LPW at 80 CRI at thermal equilibrium while remaining within the ANSI colour specification for 3000K. “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.”
