Determining the lifetime of LED products can be challenging and costly. The SSL Annex works to understand lifetime issues of LED products in support of government measurement, verification and enforcement programmes.
This research activity will include a meta-study of papers published by academic researchers, international associations/societies (e.g., IES, CIE, IEC, etc.) and testing laboratories and will result in a synthesis of information to help policy makers make decisions on SSL product lifetime. The Annex will prepare a summary of this research, explaining key features in defining, evaluating and testing for product lifetime in a format that is accessible and will provide policy guidance.
