Frequently asked questions

Match your Sterilight system's model (e.g. VH200, SP320, SC410, SSM-24) to the equivalent compatible lamp code — check the label on your UV chamber if you're not sure which model you have.

These are compatible replacement lamps, built to match the fitting and output of the original Viqua Sterilight lamp for each model, at a lower price point than genuine manufacturer parts.

Roughly every 9,000–12,000 hours, around once a year for typical continuous use — UV output drops before the lamp visibly fails, so don't wait for it to go out.

Compatible lamps are built to match the original fitting and UV output for each specific model, so performance should be equivalent — always match the lamp code exactly to your system model to ensure correct fit and output.

The lamp keeps lighting up but its UV output falls below the level needed for reliable disinfection, so water may no longer be properly treated even though the system looks like it's working.
