Self-ballasted lamps are mercury vapor lamps with a filament inside connected in series with the arc tube that functions as an electrical ballast. This is the only kind of mercury vapor lamp that can be connected directly to the mains without an external ballast. The light emitted is a combination of the mercury vapour lamp (visible, UV) and the tungsten lamp (infrared, visible).
