UVC 15W-L Wavelength C 220V/110V
We've all heard of UV-A and UV-B ultraviolet rays: they come from the sun, and they're the reason we have SPF ratings on sunscreen. Less publicly known, but effective in it's own right is the UV-C subsection of the light spectrum.
UV-C is a shorter wave ultraviolet radiation, and it can destroy bacteria, viruses, spores (including C. diff.) and other pathogens in the air, in liquids, or on surfaces. UV-C has been used in germicidal applications since the 1930's.
