The U.S. Department of Energy’s CALiPER program has released a new Snapshot Report on LED troffer luminaires. Among the key findings of the Snapshot, which is based on DOE’s LED Lighting Facts® database:
A lot has changed since the last time a CALiPER Snapshot report included troffers, which was in April 2014. Back then, the mean efficacy for troffers was 90 lm/W; today it’s 102 lm/W. In terms of the data captured by LED Lighting Facts and reported in the new Snapshot, LED troffers offer a compelling alternative to fluorescent troffers. This applies to both troffer luminaires and troffer retrofit kits, whose performance was nearly indistinguishable. While the new report focuses on basic photometric characteristics, choosing a product for a specific installation requires a more comprehensive analysis.
