2. 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 ...

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. Fluorescent lamp - Wikipedia

   en.wikipedia.org/wiki/Fluorescent_lamp

   Germicidal lamps have designations beginning with G, for example G30T8 for a 30-watt, 1-inch (2.5 cm) diameter, 36-inch (91 cm) long germicidal lamp (as opposed to an F30T8, which would be the fluorescent lamp of the same size and rating).

5. 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.

6. Ultraviolet - Wikipedia

   en.wikipedia.org/wiki/Ultraviolet

   Halogen lamps with fused quartz envelopes are used as inexpensive UV light sources in the near UV range, from 400 to 300 nm, in some scientific instruments. Due to its black-body spectrum a filament light bulb is a very inefficient ultraviolet source, emitting only a fraction of a percent of its energy as UV, as explained by the black body ...

7. LED lamp - Wikipedia

   en.wikipedia.org/wiki/LED_lamp

   A 230-volt LED filament lamp, with an E27 base. The filaments are visible as the eight yellow vertical lines. An assortment of LED lamps commercially available in 2010: floodlight fixtures (left), reading light (center), household lamps (center right and bottom), and low-power accent light (right) applications An 80W Chips on board (COB) LED module from an industrial light luminaire, thermally ...
