Abstract
Ballast circuitry for a metal halide lamp is disclosed enabling sustained operation with a typical 120 volt AC power source. A novel auxiliary circuit network is operatively associated with inductive type starting circuit means to provide lamp reignition when needed during each half-cycle of the AC power supply. The present auxiliary circuit network employs breakover switching means connected in series with capacitor storage means for further connection across the operating discharge lamp.
