What are Germicidal Lamps?


Ultraviolet lamps or commonly know as germicidal, are low pressure mercury vapour lamps which produce ultraviolet light that is lethal to microorganisms. Ultraviolet light is generated by an electrical discharge through low pressure inert gases and mercury vapour within the special quartz tube of the lamp. Approximately 95% of the UV rays from the lamp are at the wavelength of 254nm, which is the region of maximum bactericidal effectiveness.

Ozone or Non Ozone

Infralight Pty Ltd's germicidal lamps are available in "L" Quartz (non-ozone) and "VH" Quartz (very high ozone). A high level of irradiance and reliability is required for the disinfection and sterilisation of water and surfaces. Infralight supplies uv disinfection lamps and quartz sleeves made from the highest grade of fused and synthetic quartz for maxium uv output. Hot cathode lamps have triple-coiled filaments as cathodes that are heated by the arc current. Infralight utilises a filament construction with a nickel inner lead in a clamped filament design similar in construction to a standard fluorescent lamp. Slimline or instant start uv lamps utilise high voltage for starting and are especially suited to applications such as water purification. Preheat lamps use a glow switch starter to preheat the filament prior to starting and generally use standard fluorescent ballast which provide the advantages of space and economy.
