The LED Systems Reliability Consortium (LSRC) is a group of industry experts working collaboratively in an ongoing effort to deepen knowledge of LED product performance. The LSRC’s work contributes to a consistent, industry-wide understanding of LED luminaire lifetime and reliability and aims to enhance the predictability of the lifetime of LED lighting products. Selected publications on LED product performance and reliability are listed below.
