[57] ABSTRACT

The invention described hereinafter relates to an electric hand-type light especially adapted for underwater use. The new lamp is unique in several respects, especially in that the light source is adapted to be slidably positioned relative to its co-operating reflector; and, it is also easily slidably removable from its reflector association for independent use. A special light source is employed which also forms a part of the invention. The light source is of the quartz-iodide type and by reason of particular mounting features, it is rendered especially adapted for underwater use, particularly as regards its light-giving life.
