An incandescent lamp is designed to operate at lower than the AC line voltage and includes a voltage conversion circuit for lowering the line voltage to the operating voltage of the lamp. The circuit includes an output transformer which is disposed in the screw base of the lamp, the remainder of the circuit, which is high-temperature-intolerant, being disposed outside the base and the envelope of the lamp. In a reflectorized embodiment of the lamp, the high-temperature-intolerant portion of the circuit is disposed adjacent to the mouth of the reflector envelope on the outer surface thereof and, in a non-reflectorized bulb embodiment, the high-temperature-intolerant portion is disposed between the envelope and a skirt which is connected to the base.
