DOE publishes CALiPER snapshot report on indoor LED luminaires

Efficiency and efficacy are improving in LED indoor luminaires. The U.S. Department of Energy’s CALiPER program released a Snapshot Report on indoor LED luminaires. The Snapshot reports use DOE’s LED Lighting Facts program’s product database to understand the current state and trajectory of the market for a class of products.

Some of the highlights: For the 11th consecutive quarter, the mean efficacy of newly listed indoor LED luminaires has increased, and is now at 86 lm/W. Over 70% of the products meet relevant efficacy qualification criteria from energy efficiency programs. Lumen output was often similar to that of typical conventional luminaires of the same type. The dataset shows little correlation between color quality and luminaire efficacy.
