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.

A weatherproof lighting fixture for enclosing and supporting a light source, comprising: a. an optically transmissive, substantially cylindrical enclosure for said light source including i. a longitudinal axis; ii. a closed upper surface centered about the longitudinal axis; iii. a body centered about the longitudinal axis, extending downward from said upper surface and including a lower section having an outer surface and a substantially flat lower surface oriented perpendicular to the longitudinal axis, said lower surface commencing at a first radial distance from the longitudinal axis and terminating at a second radial distance from the longitudinal axis; b. a circular base formed from a thin metal sheet and including i. a circular disc section centered about the longitudinal axis, having an upper surface and terminating at a third radial distance from the longitudinal axis; ii. a circular first flange section centered about the longitudinal axis and having an upwardly extending, vertically oriented inner surface coupled to said disc section at the third radial distance, said first flange section including a downwardly extending, vertically oriented outer surface joined to the inner surface and located at a fourth radial distance from the longitudinal axis where the fourth radial distance is approximately equal to or slightly shorter than the first radial distance for enabling said first flange section to fit coaxially within the lower section of said enclosure, the space between the inner and outer surfaces defining an unobstructed downwardly facing U-shaped gap located entirely within the first radial distance with vertically oriented, parallel sidewalls, a peak evaluation and a width; iii. a horizontally oriented, circular second flange section defining the bottom of the U-shaped gap, having an inner surface coupled to and extending outward from said first flange section and having an upper surface for supporting the lower surface of said enclosure, the second flange section being elevated above the disc section and passively supporting the enclosure from below without contacting or exerting force on the outer surface of the lower section of said body, the distance between the bottom and the peak elevation of the U-shaped gap exceeding the width of the U-shaped gap; and c. clamping means having an upper clamping surface engaging the lower section of said enclosure and a lower clamping surface extending below and under the second flange section of said base to firmly bias the upper surface of said second flange section toward the lower surface of said enclosure to form a horizontally oriented weatherproof seal between the flat lower surface of the body and the horizontally oriented second flange section.
