In 2008, the Illuminating Engineering Society of North America (IES) published LM-79-08, Approved Method for the Electrical and Photometric Measurements of Solid-State Lighting Products. Why are special test procedures required for this technology, and what kind of information is gleaned from testing conducted using this new method?   View More >>

Using LEDs to their Best Advantage
Light-emitting diodes (LEDs) are often touted for their energy efficiency and long life. Although these are important considerations, selecting a light source should involve many other factors. This fact sheet explores some of the unique attributes of LEDs, which may make them the best choice for a given application.   View More >>

SSL Standards and Guidelines
Like traditional lighting equipment, solid-state lighting (SSL) products sold in the United States are subject to industry standards governing safety and performance. This fact sheet lists the key guidelines as well as performance and safety standards that are applicable to SSL products, including those utilizing light-emitting diodes (LEDs). The use of national standards and test methods improves consistency of performance and facilitates product comparisons, thereby increasing consumer confidence and satisfaction. As the technology matures, standards and guidelines are created or revised as needed. The documents listed here are those applicable in North America and completed as of October 2011.1   View More >>
