A light fixture including a fixture housing and a detachable reflector is provided with an arrangement of a cylindrical rim portion of the housing having circumferentially spaced radially outwardly projecting sets of lobes or projections which form grooves for receiving cooperating radially inwardly disposed projections on the reflector whereby the reflector may be twisted on and off of the fixture housing. The lobes on the housing are spaced apart and provided with opposed abutment surfaces which are engaged by the edges of the projections on the reflector with respect to the housing. One of the abutments includes an inclined surface whereby forcible elastic deflection of the reflector projections permits disassembly of the reflector from the housing at will. The reflector and the housing are provided with indicia to facilitate alignment, assembly and diassembly of the reflector with respect to the housing.
