A holder for infrared heat source lamps and particularly a holder comprising a block structure having entry sections on both sides separated by a wall. The separating walls provide an entry section oversized and otherwise notched to dissipate heat. A port in each entry section leads to a separate conductive bar positioned on a stair-step surface. The energization protruding wires of the infrared lamps are secured through the ports to the conductive bars. The energization wire power source for the infrared lamps is also connected to the conductive bars. Detailed refinements for positioning the holder in a reflector are disclosed.
