This UV Ozone Lamp Replacement is for use with the HydroRite sanitizing system. The UV lamp emits light at two separate wavelengths within the UV spectrum: 254 nm and 185 nm. The 254 nm wavelength is called the "germicidal" wavelength. This wavelength is capable of inactivating a wide array of microorganisms such as bacteria, viruses, protozoa, algae spores and other single vessel waterborne microbes. The 185 nm wavelength, on the other hand, is called the "ozone generating" wavelength and is responsible for converting oxygen contained in the quartz sleeve area, into ozone.
