UV-C bulbs for pond & pond - Replacement lamps & bulbs

Your UV-C device is working, but its bulb is nearing the end of its lifespan? Discover our replacement UV-C bulbs for ponds, suitable for many clarifier and sterilizer models.

Before ordering, check the device model number, the wattage, the base type, and the bulb dimensions. Use the product filters or contact our team to confirm compatibility.

A UV-C bulb may still emit visible light even though its UV-C output has decreased. Follow the replacement schedule specified by the manufacturer; for many standard lamps operating continuously, it is recommended to check and replace them every season.

Choosing and replacing your UV-C bulb

• Compatibility: check the model numbers and base (for example, PL-S, PL-L, TL, or T5 depending on the device); the same wattage does not guarantee a compatible bulb.
• Maintenance: disconnect the device before carrying out any work, check the quartz sleeve and seals, and follow the instructions for your model.
• Green water: UV-C treats suspended microalgae when the flow rate and power are appropriate; it does not replace filtration or a proper water balance.
