A GU24 light bulb is a bi-pin base lamp that is used for mains-voltage applications. The lamp is fitted to an ANSI standardized base designated as GU24. The GU24 base features two pins that twist and lock into the light fixture. As the name would suggest, the two pins are spaced 10 mm apart. The GU24 socket and base system was introduced to force the transition to more energy efficiency CFL technology because the new system would prevent the Edison screw base incandescent bulbs from being used in newer light fixtures. The Energy Star program requirements for residential lighting fixtures, Version 4.0, mandate the removal of the standard Edison screw sockets in light fixtures in favor of GU24 socket. The same requirement was also included in California’s building energy efficiency standards, known as Title 24.
