CLTC recently completed a four-year EPIC-sponsored research program that included a long-term performance evaluation of commercially available LED light sources. The study aimed to determine if today’s existing products meet their stated performance when installed in worst-case thermal conditions typical of applications designed to comply with California’s Title 24 requirements.
Evaluation results showed that the tested LED replacement lamps met most of the performance criteria claimed by their manufacturers. However, 36% of the tested lamps failed prematurely.
