ABSTRACT:
A high efficiency, electronic ballast is taught for high pressure sodium (HPS) lamps. The ballast is powered by AC line current which is rectified so that 160 volts of direct current lights the lamp. The ballast maintains constant wattage to the lamp and constant line wattage. A striker circuit develops a high voltage, short duration pulse to strike the lamp.
