Deuterium lamp (or deuterium arc lamp) is a low-pressure gas-discharge light source often used in spectroscopy when constant and intense ultraviolet light is required.

These light sources utilize a heated tungsten filament that manufactures an arc to the anode in order to energize molecular deuterium for visible and infrared light production.

Arc lamps are remarkable for their high performance in the ultraviolet, with relatively little output in the visible and infrared. Arc lamps made with ordinary light-hydrogen provide a very similar UV spectrum to deuterium, and have been utilized as a part of UV spectroscopes. However, lamps using deuterium have a longer life span and intensity at the far end of their UV range which is three to five times that of a standard hydrogen arc bulb, at the similar temperature. Therefore, Deuterium lamps are considered a superior light source than light-hydrogen arc lamps, for the shortwave UV range.
