2. Ultraviolet germicidal irradiation - Wikipedia

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

   The UV lamps for water treatment consist of specialized low-pressure mercury-vapor lamps that produce ultraviolet radiation at 254 nm, or medium-pressure UV lamps that produce a polychromatic output from 200 nm to visible and infrared energy. The UV lamp never contacts the water; it is either housed in a quartz glass sleeve inside the water ...

3. Germicidal lamp - Wikipedia

   en.wikipedia.org/wiki/Germicidal_lamp

   A 9W germicidal lamp in a modern compact fluorescent lamp form factor Glow of a germicidal lamp excited by a high voltage probe. Close-up of the electrodes and the safety warning. A germicidal lamp (also known as disinfection lamp or sterilizer lamp) is an electric light that produces ultraviolet C (UVC) light.

4. Air purifier - Wikipedia

   en.wikipedia.org/wiki/Air_purifier

   Ultraviolet germicidal irradiation - UVGI can be used to sterilize air that passes UV lamps via forced air. [21] Air purification UVGI systems can be freestanding units with shielded UV lamps that use a fan to force air past the UV light.

5. UV-B lamps - Wikipedia

   en.wikipedia.org/wiki/UV-B_lamps

   UV-B lamps are lamps that emit a spectrum of ultraviolet light with wavelengths ranging from 290–320 nanometers. This spectrum is also commonly called the biological spectrum due to the human body's sensitivity to light of such a wavelength. [1] UV-B light does not tan the skin very much, compared to the UV-A lamps that are used in tanning beds.

6. Heating, ventilation, and air conditioning - Wikipedia

   en.wikipedia.org/wiki/Heating,_ventilation,_and...

   UVC or Ultraviolet Germicidal Irradiation is a function used in modern air conditioners which reduces airborne viruses, bacteria, and fungi, through the use of a built-in LED UV light that emits a gentle glow across the evaporator. As the cross-flow fan circulates the room air, any viruses are guided through the sterilization module’s ...

7. Tanning lamp - Wikipedia

   en.wikipedia.org/wiki/Tanning_lamp

   The amount of UV that is generated from a low-pressure lamp is highly dependent on the temperature in the tanning unit. As a rule, tanning lamps produce the highest amount of ultraviolet light when this temperature is between 90 and 110 °F (32 and 43 °C). As the temperature moves away from this range, the amount of UV produced is reduced.
