Amalgam Lamp: A Source of UV Radiation

Amalgam Lamp is an intense source of ultraviolet radiation (185-253.7nm) produced by an electrical discharge on a lamp with the inner side of the lamp is covered by an amalgam of mercury with indium or gallium to control the vapour pressure of mercury. These lamps are 2-3 times more efficient for the same wavelength as the standard low-pressure mercury lamp.
