scope:

This Technical Specification provides guidance for establishing confidence in product reliability using principal component testing of LED light sources and LED luminaires for general lighting. It includes methods and criteria using initial qualification tests and accelerated stress tests of principal components. The performance of any principal component will influence the performance of the final product. Techniques to validate full life time claims and lumen maintenance projection are outside the scope of this Technical Specification. The following principal components are included when they are integral part for the LED light source or LED luminaire: - LED package and interconnects - Optical materials - Electronic subassemblies - Cooling systems, both active (e.g. fans) and passive (e.g. thermal interface material) - Construction materials This edition of the guide is not recommended for use as a normative reference to the LED product performance standards.
