Sterilight SC200-A 9 GPM (110v)


The Sterilight SC200-A UV system disinfects all the water entering your home and provides protection from bacteria and viruses in your water. In order to maintain the manufacturer's warranty, UL third-party certification, and ensure your Aquasana AQ-UV-STD Sterilight UV system is properly treating the water in your home, it is necessary to only use genuine VIQUA Sterilight S200RL-HO (formerly AQ-UV-STD-LAMP) UV lamps in your system. Genuine manufacturer lamps will have "VIQUA S200RL-HO" etched onto the lamp glass. Using any other lamp will void the manufactures warranty and may be unsafe to use. Find genuine replacement lamps, sleeves, and parts for your Sterilight SC200-A UV system below:



  • Lamp (S200RL-HO or AQ-UV-STD-LAMP) - Replace every 12 months
