An improved plastic reflector member for a parabolic aluminized reflector (PAR) lamp is disclosed and, in particular, use of said improved plastic reflector member for an all plastic PAR lamp or a PAR lamp which uses said improved reflector member. Said improved plastic reflector member utilizes a variable thickness wall member to form the parabolic shaped cavity wherein the wall thickness is sufficiently greater in the apex region of said parabolic cavity than in the adjoining wall region to avoid mechanical and heat distortion.
