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.

19. A light for installation into a niche in the wall of a pool comprising:
-
a housing having a forward end, a rearward end, and interior surface therebetween defining a chamber sized to enclose an electric light, an opening in the forward end of said housing and an opening in the rearward end of said housing;
a lens mounted across the forward opening of said housing, the lens sealing the forward opening of said housing; and
a base having a seal thereon mounted across the rearward opening of said housing, said base configured to engage said housing to hold the seal in a predetermined position radially between said base and said housing to prevent fluid from entering the chamber of said housing;
wherein said housing has a projection on its interior surface adjacent to its rearward opening, and wherein said base has a forward end, a rearward end, and a circumferential surface located therebetween, the circumferential surface defining a first slot extending circumferentially around said base and curving forwardly, the slot sized to engage the projection so that rotation of said base causes the projection to interferingly ride within the slot until said base is pulled longitudinally into the rearward opening of said housing to move the seal radially between said base and said housing. - View Dependent Claims (20, 21, 22)

23. A submersible light for installation in a niche in the wall of a pool comprising:
-
an electrically nonconductive housing having a forward end, a rearward end, and internal surface therebetween defining a chamber and an opening in the forward end of the housing;
a light socket mounted within the chamber;
an electric light mounted within the chamber, the light having a nonconductive reflector reflecting light outwardly within a predetermined frustoconical space passing through the opening in the forward end of said housing;
an electrically nonconductive lens mounted across the forward opening of said housing, the lens assembly sealing the forward opening of said housing, the lens aligned so that the light from said light passes therethrough; and
a transformer remotely located from the housing, said transformer having an isolated voltage input and voltage output, the voltage output of said transformer coupled to said light socket to define a light circuit, the only electrically conductive material of said light being the light circuit such that no ground wire is required on the submersible light. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
