Classic UV low pressure lamps have an excellent efficiency. 40% of the electric power can be used as 254 nm UV-C radiation for disinfection. If natural or synthetic quartz glass is used as lamp material, UV radiation at awavelength of 185 nm is emitted additionally for oxidation processes. Preferred applications of the UV low pressure lamps include disinfection of water, air and surfaces in the food and beverage industry and in waterworks, sewage works and air-conditioning plants.
