Paper Abstract

A free-flooded, high intensity under water searchlight consisting of 2.2 kw xenon short-arc lamp mounted at the focus of a 10-inch diameter reflector has been developed at the Naval Research Laboratory. The unique feature of the searchlight is that both the lamp and the reflector are in direct contact with water; neither one is surrounded by a water-tight enclosure as is often the case for underwater light sources. Thus, many of the disadvantages of an enclosure such as added weight and bulk, heat transfer problems, window breakage, and inaccessibility of the light source interior are overcome.
