Abstract
A programmable waveform ballast has a power supply and a waveform generator. The power supply provides, from a power source, a variable power to a discharge lamp. The waveform generator is coupled to the power supply and is programmable to produce a plurality of waveforms. The waveform generator controls the power supply to apply the variable power to the discharge lamp in accordance with a programmed waveform.
