DOE publishes Caliper report focused on tunable-white LED luminaires RSS

Initial testing of tunable SSL products was undertaken to understand the unique requirements of characterizing such products and uncovered substantial variations in performance of eight LED luminaires. The US Department of Energy (DOE) has published its first Caliper test report focused on white-point-tunable LED-based luminaires. "Report 23: Photometric testing of white-tunable luminaires" details testing of eight products at full intensity over a range of different CCTs. The initial work was focused on understanding the tests and methodology needed to accurately characterize the performance of tunable products. The Caliper testing included measurements at 11 color set points. The DOE said the...
