DOE Announces New Energy Efficiency Standards for MH Luminaires by Craig Dilouie

The U.S. DOE recently issued new energy efficiency standards for ballasts sold as part of new metal halide luminaires. (To be clear, replacement ballasts are not covered.) The new rules strengthen current standards while expanding their scope, and will affect availability of 50-1000W luminaires. The deadline for compliance is Feb. 10, 2017. The new DOE energy efficiency standards will shake up the metal halide category, promoting efficient pulse-start options, particularly electronic ballasts.
