The U.S. Department of Energy (DOE) has published an updated version of the guide LED Luminaire Lifetime: Recommendations for Testing and Reporting, the latest edition in a series of publications on LED product performance and lifetime. The guide was developed by a working group under the auspices of DOE and the Next Generation Lighting Industry Alliance, composed of a diverse group of experts in reliability, lighting, and LED technology. Their recommendations are an important step toward consistent, industry-wide understanding of LED luminaire lifetime, and will assist standards organizations in their work.
