High Output Germicidal Lamps GHO64T5L
Germicidal UVC Light Bulbs Ultraviolet germicidal light bulbs are widely used as an air, surface, and water sanitizer. UV germicidal light destroys the ability of bacteria, viruses and other pathogens to multiply by deactivating their reproductive capabilities. Germicidal light includes the UV-C...
Description


Why is UV important for the disinfection of water and air?
The portion of the UV spectrum (the “germicidal†region) that is important for the disinfection of water and air is the range that is absorbed by DNA (RNA in some viruses). This “germicidal range†is approximately 200 – 300 nm, with a peak germicidal effectiveness at about 260 nm. The mechanism involves absorption of a UV photon by pyrimidine bases (principally thymine) where two pyrimidine bases are next to each other on the DNA chain. The “photochemistry†involves formation of a “dimer†that links the two bases together. This causes a disruption in the DNA chain, such that when the cell undergoes mitosis (cell division), the replication of DNA is inhibited.

Can You Use UVC for direct human disinfection?
UVC is damaging to the skin and to the eyes. DO NOT look at the UV light or expose any part of your body. UVC should not be, and is not intended for, use for direct human disinfection.
A possible exception is far UV light (see the FAQ that is specific to far UV light).
