Abstract
A method for operating a HID lamp using a bi-power electromagnetic ballast. The method includes applying a full power level to the lamp to produce full brightness and applying a dimmed power level to the lamp to produce a dimmed brightness. The lamp may be dimmed by switching the lamp power from the full power level to the dimmed power level and then applying a full power pulse to the lamp. The dimmed power level is less than the full power level.
