Abstract
A HID dimming method and apparatus are provided. The method includes generating a dc waveform during a reduced power dimming mode of operation of the HID lamp, the reduced power dimming mode being less than the full power rating of the lamp, and driving the lamp with the dc waveform to generate a dimmed lamp output. An ac waveform may be utilized to drive the lamp during the full power mode of operation.
