A review of the main modern achievements is presented in development, production and application of UV bactericidal lamps and irradiating installations with their use to disinfect water, air and surfaces. It is shown that LIT NPO takes a worthy place among most large-scale global manufacturers of such lamps and installations.

A lot of attention is paid to the efficiency questions of modern amalgam lamps of low pressure in connection with more and more growing relevance of increasing energy efficiency of installations for water, air and surface disinfection. The real efficiency of a radiation source, as well as of the whole UV disinfection system, is an operational parameter much important for the customers. In this work, factors influencing efficiency of low pressure lamps are considered in detail. It is shown that efficiency of the modern amalgam lamps at the beginning of their lifetime is about (30–40)%.
