The reflector lamp may be of the parabolic aluminized reflector (PAR) or the reflector (R) type lamps having primary, multiple intermediate and rear sections of a parabolic contour which improves the internal light reflective and absorption characteristics of the reflector lamp. The overall effect is to improve the optical efficacy of the reflector lamp.
