The Viqua S810RL UltraViolet Lamp is a replacement bulb for the Viqua S8Q-PA and SV8Q-PA systems and the discontinued Sterilight SSM-37 system. This bulb provides protection from occasional intrusion by microbial contaminants, eliminating up to 99% of bacteria, Cryptosporidium, E. Coli, and viruses. During ultraviolet sterilization, water is exposed at a controlled rate to UV light waves, which deactivate the DNA of microorganisms and prevent them from reproducing. Easy to install and maintain with replacement needed every 12 months. Order the S810RL Viqua Water Disinfection System UV Lamp today!
