Most people don’t think of light as a means of purifying or disinfecting, but special OSRAM “germicidal” lamps emit high intensity ultraviolet light that purifies air, water, and surfaces without the use of harsh chemicals that are harmful to the environment. For effective purification the wavelength and intensity of the irradiance is critical. OSRAM PURITEC^® HNS^® germicidal lamps provide peak intensity at 254nm that is ideal for highly effective sterilization of water, air and surfaces.
