Abstract
Improved seating or mounting pads are provided in a plastic reflector for a parabolic aluminized reflector (PAR) lamp and, in particular, hollow mounting pads are located at each corner of a rectangular shaped plastic reflector member to avoid deformation of the parabolic cavity when the reflector member is formed. In a preferred embodiment, the reflector member is of a unitary molded construction which further includes a sealing rim and with said mounting pads comprising semi-circular hollow boss elements which are located on the rear surface of said sealing rim and project backwardly therefrom to terminate on the parabolic cavity surface.
