ABSTRACT:
An underwater light source includes a sealed beam arc lamp within a wrought and machined, generally cylindrical aluminum housing. The watertight housing has an enlarged diameter at one end to receive the lamp and tapers to a smaller diameter at the other end, which receives the ignitor for the lamp. The larger end is covered with a heat resistant cover glass, and the smaller end is closed. A cylindrical accessory mounting ring is attached to the front end of the housing, and the ring has ventilation openings therein to release heat generated by the lamp.
