There is described a multi-configurational, multi-functional electrical lighting fixture for high-abuse application and structured for surface mounting. The fixture includes a lens of U.V. stabilized, high impact-resistant, injection molded polycarbonate plastics, integrally formed with two selective, separate and distinct, high-performance reflector/refractor surface systems carried by the single lens, as separate zonal areas. The first system generates a long and narrow "throw", and the second system a short and wide "throw". A molded, opaque "eyelid" provides optimum lamp shielding and controls light distribution. The lens surmounts a lens base to which it is secured by means of unique internal, integrally-molded lugs received in cooperating hook-shaped slots. An 0-ring gasket establishes a water-tight seal. Unlocking of the assembly is deterred by means of a single, tamper-resistant screw. The lens base is mounted on a deep casting, with or without an interposed cast aluminum baseplate. Alternatively, the lens base may be mounted directly on the cast aluminum baseplate, without the deep casting, to provide a low-profile fixture structure.
