What Type Bulb Do UV Sterilizers Use?
By attacking certain nucleic acids (i.e., RNA and DNA), ultraviolet (UV) light can sterilize (if not kill) microorganisms. Therefore, manufacturers now offer UV sanitizers: devices that sterilize surfaces through the use of light bulbs that emit photons in the germicidal “UVC” spectrum. Most of these bulbs are filled with mercury (Hg) vapor which, when excited by electrical current, emit ultraviolet photons. However, a few manufacturers offer light-emitting diode (LED) lamps that can produce primarily UVC photons.
