Abstract
A multimovable plastic lamp fixture. In the preferred embodiment, the lamp fixture includes a pair of lampholders for supporting a pair of floodlights or the like. Each of the lampholders are attached to a base by means of a ball and socket-type joint. The ball joint is located off-center and provides spherical positioning of the lights. A gasket located in the interior of each socket prevents moisture from entering the base and, in addition, maintains each lampholder in position due to friction. The ball and socket joint includes a knee ball cover having a semi-spherical surface for engaging the ball joint. Tabs located on the outer surface of the knee ball cover limit the rotational movement of each lampholder with respect to the base.
