ABSTRACT:
A lighting apparatus includes a housing and a lamp support assembly that is normally retained in but removable from the housing. The lamp support assembly includes coaxial inner and outer sleeves, and a lamp socket mounted on one of the sleeves. The inner sleeve is movable relative to the outer sleeve between a braced position in which the lamp support assembly is retained in the housing, and a released position in which the lamp support assembly is released for removal from the housing. A lamp is received in the socket, and the inner sleeve is biased toward the braced position when the lamp support assembly is positioned in the housing so that the lamp support assembly is retained in the housing.
