Abstract
Abstract An underwater floodlight assembly in which an open-ended shell extends in an opening formed in the wall of a reservoir for water, with the shell having an outwardly extending integrally formed flange which engages the surface of the wall. A plurality of integrally formed bosses extend from the flange and into the wall. An open-ended inner housing is disposed within the shell and includes a receptacle for a lightbulb, and a mounting assembly mounts a cover over the open end portion of the housing and the shell. An insert of an electrical conductive material is molded integral with the flange and is connected to ground, and the mounting assembly establishes an electrical current flow path from the housing to the insert.
