Benefits

Ultraviolet (UV) light is produced by the sun and by special lamps. There are three types of UV light—UVA, UVB, and UVC. UVC light has the most energy of the three types. This energy destroys the genetic material inside viruses and other microbes. Therefore, UVC light is used for disinfection. UVC lamps and robots are commonly used to sanitize water, objects such as laboratory equipment, and spaces such as buses and airplanes. (Source: National Academy of Sciences).
