ABSTRACT:
A jacketed high pressure metal vapor discharge lamp comprising an arc tube having main electrodes at opposite ends and a starter electrode, has a resistor and a diode in series bridged across the main electrodes which are connected across a peaked lead ballast in operation. A second resistor connects the starting electrode to the remote main electrode. The circuit lowers the minimum open circuit voltage required from the ballast for reliable starting.
