A Germicidal lamp is a lamp that produces a special type of ultraviolet light. This light can ionise oxygen and produce ozone. Ozone can kill many types of germs. There are different designs of such lamps; some are very similar to compact fluorescent lamps.
In bactericidal lamps, the spectrum of ultraviolet radiation is selected in such a way as to minimize the formation of ozone and harmful effects on the skin and eyes by cutting out the hard ultraviolet lamp from the radiation spectrum. They try to leave only the spectral line of soft ultraviolet with a wavelength of 253.7 nm. Such lamps are also called "ozone-free" due to the minimization of ozone formation. After quartz treatment with a bactericidal lamp, it is not necessary to ventilate the room, unlike a quartz lamp.
Germicidal lamps are used for disinfection of indoor air and surfaces, disinfection of drinking water, sterilization of objects and medical instruments. Neutralize the main part of microorganisms, such as bacteria, viruses, fungi and spores.
Bactericidal lamps are used in various devices, such as bactericidal irradiators, bactericidal recirculators, water disinfection devices, etc.
When working with bactericidal lamps, it is necessary to remember about the danger of ultraviolet light for vision and skin.
