  2. Germicidal lamp - Wikipedia

    en.wikipedia.org/wiki/Germicidal_lamp

    A germicidal lamp (also known as disinfection lamp or sterilizer lamp) is an electric light that produces ultraviolet C (UVC) light. This short-wave ultraviolet light disrupts DNA base pairing , causing formation of pyrimidine dimers , and leads to the inactivation of bacteria , viruses , and protozoans .

  3. Ultraviolet germicidal irradiation - Wikipedia

    en.wikipedia.org/wiki/Ultraviolet_germicidal...

    Ultraviolet germicidal irradiation (UVGI) is a disinfection technique employing ultraviolet (UV) light, particularly UV-C (180–280 nm), to kill or inactivate microorganisms. UVGI primarily inactivates microbes by damaging their genetic material, thereby inhibiting their capacity to carry out vital functions.

  4. Deuterium arc lamp - Wikipedia

    en.wikipedia.org/wiki/Deuterium_arc_lamp

    Arc lamps made with ordinary light-hydrogen provide a very similar UV spectrum to deuterium, and have been used in UV spectroscopes. However, lamps using deuterium have a longer life span and an emissivity (intensity) at the far end of their UV range which is three to five times that of an ordinary hydrogen arc bulb, at the same temperature.

  5. Gas-discharge lamp - Wikipedia

    en.wikipedia.org/wiki/Gas-discharge_lamp

    A flicker light bulb, flicker flame light bulb or flicker glow lamp is a gas-discharge lamp which produces light by ionizing a gas, usually neon mixed with helium and a small amount of nitrogen gas, by an electric current passing through two flame shaped electrode screens coated with partially decomposed barium azide. The ionized gas moves ...

  6. Mercury-vapor lamp - Wikipedia

    en.wikipedia.org/wiki/Mercury-vapor_lamp

    Color corrected" mercury bulbs overcome this problem with a phosphor on the inside of the outer bulb that emits at the red wavelengths, offering whiter light and better color rendition. Mercury-vapor lights operate at an internal pressure of around one atmosphere and require special fixtures, as well as an electrical ballast. They also require ...

    en.wikipedia.org/wiki/Talk:Germicidal_lamp

    Normally, the quartz envelope of standard low-pressure germicidal "G-series" fluorescent lamps is intentionally doped with materials to absorb mercury emissions below 254nm. This is to prevent ozone production in situations where ozone is not desired (in an EPROM eraser or mineral-hunting lamp, for example).
