DOE Report Looks at High-Efficacy LED Luminaires

The US Department of Energy (DOE) has released a short report covering testing of rectilinear LED luminaires intended for high-output applications such as low- and high-bay lighting in industrial or commercial settings. The testing was focused on seven solid-state lighting (SSL) luminaires that had been touted by manufacturers to deliver efficacy in the range of 200 lm/W. The mixed results include measured photometric performance and subjective analysis for visual comfort and acuity under the lighting. The testing took place at the DOE’s Pacific Northwest National Laboratory (PNNL) where researchers sought to verify high-efficacy performance and discover any subjective or measured performance issues that resulted from manufacturers pushing the lumen output to high levels.
