Advanced LED Lights for determining Effective Useful Life

This project is aimed at understanding the actual EUL values of LED based products by performing a combination of field measurements, lab evaluation, and data compilation. This effort consists of (1) field measurements of deployed LED based lighting to determine their current performance and rate of lumen decline; (2) compilation of LED based lighting lifespan testing data from a range of lighting applications (residential, commercial, and industrial, both interior and exterior) which has been conducted by other agencies / groups. (3) the laboratory testing of up to 50 lamps / fixtures from a range of applications (including A-line lamps, PAR lamps, streetlight / parking fixtures and troffer fixtures) to evaluate their decline during this project’s timeline.
