ABSTRACT:
The invention comprises a self-adjusting ballast system for a high intensity discharge lamp. The ballast has a current limiter which modifies the lamp's present duty cycle to prevent damage if bulb rectification or another overcurrent condition occurs. It also has a current integration feedback loop for controlling lamp current during start-up.
