PAR Halogen Lamps that meet EISA 2007 are energy-efficient bulbs designed to comply with the U.S. Energy Independence and Security Act (EISA) of 2007. These lamps, such as PAR20, PAR30, and PAR38, provide bright, focused light while consuming less energy than traditional halogen lamps. They are ideal for applications like track and recessed lighting and offer improved efficiency while maintaining high color rendering and light output.
