The invention offers an improvement in lighting control systems by providing a simplified power switching control system (i.e., using direct AC line voltage or DC current power switches instead of low voltage switches that control higher-current-capable relays) that controls the power to the power supplies that drive the light producing devices in a plurality of luminaires or lighting fixtures in a given installation. The lighting control system facilitates multiple modes of lighting configurations while requiring fewer switches that the prior art and also being easier to operate. The system supports the simultaneous use of multiple lighting technologies. Other embodiments showing extensions to the invention are also disclosed.
