A universal voltage fuser heater lamp is described for use in either United States or European markets having different voltage standards. The fuser lamp comprises first and second filaments having equal resistance and a switching mechanism for connecting a power supply to the fuser lamp. The switching mechanism connects the first and second filaments in a parallel configuration when the voltage is 120 Volts and connects the first and second filaments in series when the voltage is 240 Volts from the power supply.
