The most complete SSL standard in history and ***

As the development and development of standards will help strengthen market confidence in solid-state lighting (SSL) performance, the US Department of Energy (DOE) closely cooperates with standard setting organizations and provides them with technical assistance and support. This support includes assistance with product performance testing, statistical evaluation, data collection and analysis, and document development. Its purpose is to accelerate the development of standards for implementing SSL products.

The following are current and ongoing standards and white papers on SSL.

IES LM-79-2008, approved for electrical and photometric testing methods for solid-state lighting equipment, enables the calculation of the efficacy of LED lighting fixtures (using net light output data divided by the lamp's input power to measure lumens per watt). Luminaire efficacy is the most reliable method of measuring the performance of an LED product. It measures the performance of a fixture as a whole and replaces the traditional method of measuring lamp efficiency that relies on separate lamp ratings. The LM-79 can help establish benchmarks that accurately compare luminaire performance, not only for solid-state lighting, but for all light sources.

The IES LM-80-2008, which is approved as a method for measuring the lumen attenuation of LED light sources, defines the method for depreciation of test lamps. LED packages, and most light sources, lose their glow over time, which is called light decay. However, since LED packages have a long life in the conventional sense, they may become unusable before an actual failure occurs, and special definition is required for such failures. The LM-80 establishes a standard method for LED light decay testing. It should be noted that the specific level of light that is depreciated by the LED light source, but should not be interpreted as measuring the life of the luminaire, because other failure modes may also exist therein, and in most cases will shorten its life.

The IES LM-82-2012, which is recognized as a method of describing the electrical and photometric performance of LED light engines and LED lamps as a function of temperature, provides a method for measuring the lumen attenuation of light engine products at different temperatures to support the establishment of consistent tests. Methods to help luminaire manufacturers determine the reliability and lifetime characteristics of LED luminaires, thereby helping manufacturers in the selection of LED light engines and lamp luminaires.

IES LM-84-2014, measuring luminous flux and color maintenance of LED lamps, light engines and luminaires, provides methods for measuring luminous flux and color maintenance of integrated and non-integrated LED lamps, light engines and luminaires. This method is based on consistent environmental conditions throughout the laboratory, achieving reproducible results and results that are more reliable.
