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. It can also be used to produce ozone for ...

3. Ultraviolet germicidal irradiation - Wikipedia

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

   Ultraviolet light-emitting diode (UV-C LED) lamps emit UV light at selectable wavelengths between 255 and 280 nm. [74] Pulsed-xenon lamps emit UV light across the entire UV spectrum with a peak emission near 230 nm. [75] This process is similar to, but stronger than, the effect of longer wavelengths producing sunburn in humans. Microorganisms ...

4. 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.

   In the beginning of quarantine, my doctor friend told me she was absolutely obsessed with her PhoneSoap ($80), a device built to fit a smartphone that uses UV-C light to kill harmful pathogens ...

6. Far-UVC - Wikipedia

   en.wikipedia.org/wiki/Far-UVC

   The location of 'far-UVC' radiation (200-235 nm) in the electromagnetic spectrum. Far-UVC is a type of ultraviolet germicidal irradiation being studied and commercially developed for its combination of pathogen inactivation properties and reduced negative effects on human health when used within exposure guidelines.

7. Tanning lamp - Wikipedia

   en.wikipedia.org/wiki/Tanning_lamp

   Unfiltered light from a high-pressure lamp is rich in UVC used in germicidal lamps, for water purification, but it damages human skin. The contents of a high-pressure lamp are inert gas (such as argon) and mercury. [2] There are no phosphors used, and the mercury is clearly visible if it is not in a gaseous state.
