Abstract

Circuits are disclosed for use in a gaseous-discharge lamp lighting system which provide starting pulses to the lamp and/or a source of auxiliary light. One circuit provides starting pulses and/or auxiliary light until the gaseous-discharge lamp approaches its normal operating condition, while other circuits terminate these functions once the gaseous-discharge lamp ignites.
