Abstract: A driver (10) produces a current to generate traveling waves of voltage for low levels of illumination and an arc voltage for high levels of illumination through a gas discharge lamp (50). At the low illumination levels the traveling waves of voltage are produced in a manner so as to increase the current in the lamp at a controlled rate so that the increase in current can be stopped by an optical or ionization feedback loop when the lamp reaches the glow discharge region, after the Townsend discharge region and before the arc discharge region.
