What is the Filament Voltage?

Filaments are designed to get to operating temperature when an appropriate voltage is applied, e.g. 120 volts or 12 volts in the case of incandescent lamps or MR16 lamps. In certain fluorescent lamps the filament voltage is the low voltage applied to the cathode to energize it for electron emission.
