A light fixture for underwater use in swimming pools has a waterproof gasket between the lens and the housing enclosing the electrical components. The gasket is fabricated of an off-white, neoprene material and is devoid of any coloring agents, such as carbon black, which are subject to leaching by chlorine-containing water in the pool. As a result, discoloration of the wall of the pool and also of the lens will not occur, even where chlorine concentrations are relatively high.
