HEISSNER UV-C Replacement Lamps

UV-C replacement lamps for UV-C pond clarifiers

To ensure your UV-C pond clarifier consistently operates at peak performance, you should replace the UV-C bulb regularly. Choose the best one for your device from the HEISSNER product range. Note that even if your bulb still appears to be lit, its germicidal power diminishes significantly over time.

By replacing the bulb regularly, you'll ensure that your pond clarifier continues to fight suspended algae effectively and that your filtration system receives the best support in purifying the water. HEISSNER offers bulbs with a wide range of wattages that are compatible with the various pond clarifier models.

How to find the right UV-C replacement bulb:
To ensure that your clarifier continues to function properly, make sure you choose a bulb that is compatible with your clarifier. Choosing the right bulb depends on:

  • The design and socket type of your clarifier
  • The exact wattage (e.g. 5 W, 9 W, 11 W or higher)
  • The UV-C pond clarifier model

Only use bulbs explicitly intended for your system to avoid technical defects.

Service life and ideal time for replacement:
Although a UV-C bulb often still emits a blue light, its radiation power diminishes significantly over time. Regular replacement is essential to continue effectively combating germs and algae blooms and to provide the best possible support for your filtration system.

Here are the most important rules for replacement:

  • When to change? It is best to replace the lamp once a year in spring before the start of the new pond season.
  • Lifespan: The average service life is around 6,000 to 8,000 operating hours, which corresponds to exactly one season (spring to autumn).
  • Warning signs: Should your water remain cloudy (green water) despite the filtration system running, this is a clear indication of an exhausted bulb that is no longer functioning as it should.

This routine annual check ensures constant water purification and contributes significantly to the long-term stability of your ecosystem.
