The DOE LED Systems Reliability Consortium (LSRC) is a group of industry experts working collaboratively in an ongoing effort to develop an advanced luminaire reliability model for SSL manufacturers and end users. Progress on the LSRC’s efforts is reported periodically at DOE SSL workshops and other meetings, contributing to a consistent, industry-wide understanding of LED luminaire lifetime and reliability.
In 2014, the LSRC’s efforts transitioned to the Next Generation Lighting Industry Alliance, and the latest in a series of publications on LED product performance and reliability was published. With a model in place to enhance the predictability of the lifetime of LED lighting products, consumer confidence will increase and in turn accelerate adoption.
