HEISSNER UV-C Replacement Lamps
UV-C replacement lamps for UV-C pond clarifiers
Replacement UV-C Lamps ensure the full performance of UV-C Pond Clarifiers. Even if a UV-C lamp is still glowing, its germicidal effectiveness decreases over time. Regular replacement ensures that suspended algae are reliably reduced and that pond filters receive optimum support.
Replacement UV-C Lamps by HEISSNER are suitable for various UV-C pond clarifier models and are available in different wattages. They guarantee constant UV-C output and contribute to the stabilisation of the biological balance in the garden pond.

Why do UV-C lamps need to be replaced regularly?
UV-C lamps lose radiation intensity over time. Although they may continue to radiate light, the effective UV-C output decreases significantly. As a result, it is less effective in reducing algae and germs.
Timely replacement ensures that:
- Water clarification remains constant
- The filtration system receives optimum support
- Algae blooms are contained at an early stage
How long does a replacement UV-C lamp last?
- Recommended service life: approx. 6,000–8,000 operating hours
- In practice: usually one pond season (spring to autumn)
- Recommended replacement: once a year before the start of the season
Even if the lamp is still illuminating, it should be replaced after this period to ensure full clarification performance.
Which replacement UV-C lamp is the correct one?
The appropriate replacement lamp depends on:
- The model of the UV-C pond clarifier
- The wattage (e.g. 5 W, 9 W, 11 W, 18 W, 24 W, etc.)
- The socket type and design
It is essential to use only compatible lamps designed for the specific device.
When should the UV-C lamp be replaced?
- Before the start of the pond season (spring)
- In the event of persistent green water despite a functioning filter system
- After reaching the recommended operating hours
Regular lamp replacement contributes significantly to water quality and long-term pond stability.
