The ENERGY STAR program, sponsored by the U.S. Environmental Protection Agency and the U.S. Department of Energy, promotes the use of energy-efficient products, including residential luminaires. Manufacturers sign an agreement to develop luminaires that meet an energy efficiency performance specification. The products are labeled for easy identification by consumers. In addition, the ENERGY STAR program provides educational support for consumers. The program also promotes the products to utilities and organizations that purchase large numbers of residential luminaires, such as universities and hotels.
