Description
There are many websites to find information about LED lighting, the following are a few that may be of interest to you. DOE Solid State Lighting Program The U.S. Department of Energy (DOE) has made a long-term commitment to provide national leadership to advance research, development, and market introduction of solid-state lighting. DOE’s support of solid-state lighting is essential to ensure the development of energy-efficient, high performing LED technology—a focus that, without DOE leadership, might be lost on the path to commercialization. ENERGY STAR Solid-State Lighting Program The ENERGY STAR program for Solid-State Lighting establishes criteria that manufacturers can use to promote qualifying products and gives consumers confidence that products meet strict efficiency and performance levels established by DOE. Both residential and commercial products are covered. Industry Standards and Test Procedures for Solid-State Lighting IESNA LM-79 Approved Method for the Electrical and Photometric Testing of Solid-State Lighting Devices Specifies a standard test method for measuring the photometric properties of SSL devices, allowing calculation of luminaire efficacy. Electronic copies may be purchased online through the IES store. ANSI C78-377-2008 Specification for the Chromaticity of Solid-State Lighting Products Specifies recommended chromaticity (color) ranges for white LEDs with various correlated color temperatures (CCTs). Available free as an electronic download. * IESNA LM-80 Approved Method for Measuring Lumen Depreciation of LED Light Sources Specifies a standard method for measuring the lumen depreciation of LEDs, which allows calculation of LED lifetime. Electronic copies may be purchased online through the IES store. * DOE’s CALiPER Testing Program Independently tests and provides unbiased information on the performance of commercially-available SSL products. A Division of U.S. DOE SSL Quality Advocates is a voluntary pledge program to assure that LED lighting is represented accurately as it reaches the market.
