UV disinfection lights use Ultraviolet germicidal irradiation (UVGI) as a disinfection method by emitting short-wavelength ultraviolet light to kill or inactivate microorganisms. By destroying nucleic acids and disrupting the microorganism's DNA, UV disinfecting lights leave microorganisms unable to perform vital cellular functions. Disinfecting lights is used in a variety of applications, such as food, air, room and water purification.More recently, Handheld UV Disinfection Lights are being used to disinfect corona virus and bacteria on surfaces, including work stations, machines, tables and more.
