Definition:
Intense source of ultraviolet (185 and 253.7 nm) radiation produced by an electrical discharge in a lamp with the inner side covered by an amalgam of mercury with another element such as indium or gallium to control the vapour pressure of the mercury. These lamp have 2-3 times the UV output for the same wavelength as the standard low-pressure mercury lamp.
