ABSTRACT:
A jacketed high intensity discharge lamp utilizes a starter electrode voltage doubling circuit comprising a diode and a mica-dielectric capacitor which is electrically interposed between an inlead into the jacket and the frame side rod and forms an integral structural part of the frame which supports the arc tube. The starter electrode is resistively connected to the side rod to facilitate starting and the arrangement maintains a positive D.C. bias on the frame which reduces electrolysis of sodium through the arc tube walls.
