Abstract
A high power short arc gas discharge lamp includes an electrically insulating reflector body having a concave internal reflector surface with a focal point; an anode and a cathode spaced from the anode to create an arc gap between them proximate the focal point; the reflector body having a conical external surface for reducing the thickness of the reflector body between the concave internal surface and the conical external surface; and an external electrically isolated heat sink mounted on the external conical surface proximate the arc gap.
