Abstract
A system for providing a controllable current to a high intensity discharge lamp is provided. The system includes a current controller that is configured to receive input power and to provide an output current waveform to the high intensity discharge lamp. This current causes a discharge of light from the lamp. The output current waveform includes an absolute value amplitude in each half cycle that is generally constant during a first portion and that which increases non-linearly from the generally constant amplitude to a peak amplitude during a second portion.
