A portable battery powered high intensity lighting system that produces solar quality illumination at four to six times the efficiency of comparable incandescent lighting systems includes a light head and a power source. The light head contains an HID (high intensity discharge) arc lamp. A sealed enclosure containing a ballast is attached immediately adjacent to the lamp assembly. The ballast enclosure is preferably potted with a thermally conductive epoxy.
