Abstract: An ignitor disabler for the starter circuit of a High Intensity Discharge (HID) lamp includes means for disabling the ignitor, and means for triggering the disabling means of the ignitor after passage of a predetermined amount of time. The triggering means has a timing component that begins time measuring operation only under certain, predetermined conditions. The disabler includes means for resetting the timing component of the triggering means upon lamp ignition. In its preferred embodiment, the starter circuit specifically includes a power supply portion in use to convert alternating current to direct current and designed to provide a stable direct current output over a broad range of input signals.
