Accelerated Stress Testing of Multi-Source LED Products

You are here

A report series that uses accelerated stress testing (AST) to provide insights into the long-term behavior of commercial products utilizing different types of mid-power LEDs (MP-LEDs) integrated into the same LED module. The first report in the series provides initial AST results from two commercial lamps intended for use in horticulture applications and one tunable-white LED module intended for use in educational and office lighting applications. The second report focuses on determining the mechanisms of optical change in the same products.
