Infrared light sources, along with their methods of formation, are provided. The infrared light source can include a base Substrate defining an aperture; a filament extending through the aperture defined by the base substrate; a resistive metal wire wrapped around the filament to define a coil having a first end and a second end; a high temperature coating Sur rounding at least a portion of the filament and the coil; a first electrode electrically connected to the first end of the coil; and a second electrode electrically connected to the second end of the coil.
