ABSTRACT:
A lamp ballast for operating a high intensity discharge lamp includes an electronic ballast circuit to supply an operating voltage to the discharge lamp, and an igniter circuit to supply starting pulses to the discharge lamp in a cold state and to supply hot restrike pulses to the discharge lamp when the discharge lamp is in a hot state following turn-off. The hot restrike pulses are sufficient to maintain ionization in the discharge lamp but do not cause the discharge lamp to generate substantial light output.
