Abstract

A submersible light having an electrically nonconductive reflector and no other electrically conductive elements requiring grounding, a tough lens to withstand impacts from swimmers and features providing quick and easy serviceability. Because of these features, the light of the invention meets safety requirements allowing the light to be mounted less that 18 inches below the waterline, thereby allowing its placement in areas of pools that have been heretofore off limits to conventional lights. In addition, a cord holder about the external surface of the light's housing and twist lock base and housing with a radial O-ring seal provide for quick and easy disassembly and re-installation of the light.
