A tubular infrared lamp is mounted within the confines of a reflector and includes flattened, jacketed terminal structure on each end of the tube. Each terminal end extends through appropriately sized apertures in the opposed end walls of the reflector with the apertures including notches for receipt of the flattened terminals. Insulated terminal posts are mounted on the exterior side of the reflector end walls and wire leads extend tightly between the lamp ends and the corresponding post to secure the lamp against excessive axial movement. An insulating shield having an aperture, including notches, of similar size and configuration as the aperture of the end walls is disposed against the external surface of the end wall. The shield is oriented so that the notches of each respective aperture are in non-alignment, thus blocking cooling air flow, passing over the lamp ends, from entering the reflector. Also, the lamp's terminal ends are electrically shielded from the metal end wall of the reflector by the insulating shield.
