Replacement Germicidal UV Lamps

Replacement UV lamps are essential for keeping your UV water treatment system working effectively. Even if a lamp still lights up, its UV output reduces over time, which is why most UV lamps should normally be replaced every 12 months to maintain proper disinfection performance.

We supply compatible replacement UV lamps for a range of UV water treatment systems, helping customers keep their units running safely and efficiently.

UV systems are commonly used on private water supplies, boreholes, wells and domestic water treatment systems where microbiological protection is important. Replacing the lamp at the correct interval helps ensure the system continues to perform as intended and gives you confidence that your UV unit is still providing effective treatment.

Choosing the correct lamp is important, as UV lamps are not one-size-fits-all. The right replacement will depend on the make and model of your unit. If you already know the lamp reference or system model, you can browse the products in this category to find a suitable match.

If you are not sure which lamp you need, or you cannot find the one you are looking for on our website, please email us with the make and model of your system and we will do our best to help identify the correct replacement.

Why replace a UV lamp every 12 months?

Most UV lamps are designed to be replaced after around 12 months of use. This is because the germicidal performance of the lamp gradually drops over time, even if the lamp still appears to be working. Replacing the lamp on schedule helps maintain the effectiveness of your UV water treatment system and reduces the risk of poor UV performance.

If you can not find the lamp you are looking for, send us the details and we will check whether a suitable compatible lamp is available.
