A fluorescent lighting fixture designed for outdoor use and constructed mainly of polyvinyl chloride. The fixture includes a cylindrical housing made entirely of white high density polyvinyl chloride with an annular ring projecting from its inner wall, a U-shaped standard voltage fluorescent lamp, a socket for said lamp, a circular base supporting said socket and resting on the ring of the cylindrical housing, a retaining ring resting on the upper edge of the circular base, a closed-ended tubular transparent diffuser resting on the upper edge of said retaining ring, a pair of flexible O-rings encircling the lower open end of said diffusor for securing the diffuser within the housing, a circular rear bushing, and a power line passing through a hole in the base plate for energizing said lamp. The U-shaped fluorescent lamp is sealed within the housing by the two O-rings and the closed-ended tubular diffuser.
