The HID ballast allows for lower-wattage bulbs, flicker-free illumination, and the absence of a central computer.

Two primary purposes are served by the ballast's main controller circuit. First, it inverts the power into an AC signal, then it regulates the voltage output while the bulb burns by detecting resistance in the bulb thousands of times per second. Second, it modifies the output to ensure that it complies with the
