A 9W<unk>  in a modern compact fluorescent<unk>  form factor Glow of a<unk>  excited by a high voltage probe. Close-up of the electrodes and the safety warning A<unk>  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 water disinfection. They are used in ultraviolet<unk>  irradiation (UVGI). There are four common types available: * Low-pressure mercury<unk> s * High-pressure mercury<unk> s * Excimer<unk> s * LEDs
