ABSTRACT:
An electric luminaire is provided having an interior comprised of weather and corrosion resistant housing of non-metallic material, such as plastic. The housing defines an internal cavity, in which the electrical components of the luminaire reside, entirely sealed against intrusion of corrosive elements present in the atmosphere of the external environment. A rigid unitary metallic support structure, carried by a mounting hub adapted to be attached to an external support, extends from the mounting hub through the cavity and to the optical components at the lower end of the luminaire. The rigid support structure provides both primary and supplemental, or back-up, support for the electrical and optical components of the luminaire.
