Abstract
An optically transmissive, substantially cylindrical enclosure surrounds a light source. A generally circular base includes a vertically oriented first flange section dimensioned to fit coaxially within a vertically oriented lower section of the enclosure. The base includes a horizontally oriented, second flange section coupled to the first flange section and oriented perpendicular to the longitudinal axis of the lightining fixture. A circular clamp compresses a resilient gasket between a lower, horizontally oriented surface of the enclosure and the horizontally oriented second flange section of the base to create an hermetic seal between the base and the light fixture enclosure.
