A deuterium arc lamp is a type of light source that produces ultraviolet (UV) light by creating an electric arc between two electrodes in a gas-filled chamber containing deuterium, a stable isotope of hydrogen. Deuterium has one proton and one neutron in its nucleus, making it heavier than regular hydrogen.
