A reflector for an electric light has a first reflector member with a socket for the light bulb and a second reflector member positioned generally forward of the socket. In one aspect of the invention a first angular segment of the first reflector defines curved reflector means for reflecting light from the light in the socket into a collimated beam. The remaining angular segment of the first reflector defines a transversely directed, curved reflector for focusing light from the light bulb back to the filament in the light bulb to increase the filament temperature. In another aspect of the invention, the first, angular segment of the second reflector member defines a transparent partition, with the partition carrying a plurality of transparent ridges of triangular cross section. The ridges are circumferentially disposed at different radii about an extension of the central axis of the socket. Thus light from the light bulb in the socket is diffracted by the ridges into the collimated beam.
