Viqua UV replacement lamps are a low pressure, regular intensity mercury vapour lamp. These UV lamps ultilize 425 mA of current to fire at a 254nm wavelength of light. This wavelength renders microorganisms inactive. The Viqua UV lamps have several pin configurations from 4 pin stepped, standard 4 pin, and even 2 pin lamps.
NOTE: O-Rings are sold separately and require annual replacement.
