ABSTRACT:
A system and associated method for operating a gas discharge lamp so as to provide a positive voltage-current characteristic. An AC or DC source is used to provide electron heating, without in itself providing ionization, of the lamp gas. Superimposed on this signal is a pulsed source of power having an average output power substantially less than the AC or DC source power for providing ionization of the lamp gas.
