DoE Evaluates High-Efficacy LED Luminaires

Craig DiLouie August 23, 2018

A new Department of Energy study evaluated the performance of several LED lighting products with claimed efficacies near or exceeding 200 lumens/W.

The purpose: validate the claimed efficacy, determine the features or characteristics the products had in common, and identify any performance tradeoffs in luminaires reaching this very high efficacy level.
