Full details
The Pond Planet Replacement PLL UV Lamp is designed for pond owners looking to maintain clear water by effectively combating algae-causing organisms. Manufactured by Philips, this high-quality 55-watt germicidal bulb is ideal for those using 2G11-compatible UVC filtration units, offering a reliable way to ensure maximum disinfection capacity. While this bulb is highly effective at clearing green water, it is important to remember that it emits UV-C radiation, which is harmful to skin and eyes, requiring careful handling and containment within an appropriate, closed UVC housing.

FAQs
How often should I replace my UV lamp?
Pond Planet recommends replacing the bulb every spring to ensure the unit operates at its maximum capacity throughout the high-demand summer season.
Can I touch the UV bulb with my bare hands?
It is not recommended. Oils from your skin can cause uneven heating on the glass, which can significantly reduce the lifespan of the lamp.
Is this bulb compatible with all pond filters?
This bulb is compatible with UVC units that use a 55W 2G11 4-pin connection. Please check your specific filter manual to confirm wattage and connection requirements.
Will this bulb kill the fish in my pond?
No, the UV-C light is contained entirely within the filtration unit. It only affects the water and microorganisms that pass directly through the UVC chamber.
What does the 254nm wavelength do?
This specific wavelength of UV-C light is the peak range for germicidal action, effectively disrupting the DNA of algae, bacteria, and viruses.
Troubleshooting
The UV lamp does not light up
Check that the 4-pin connection is seated firmly in the 2G11 socket and verify that the power supply to the UVC unit is active.
Water remains green despite the bulb being on
The bulb may be at the end of its effective lifespan; even if it glows, the UV-C output may be insufficient. Replace the bulb if it has been in use for more than one season.
Bulb flickers shortly after installation
Ensure the connection is clean and free of debris. If the issue persists, the UVC ballast or starter within your filtration unit may need to be inspected for faults.

Setup, Compatibility & Care
Installation involves ensuring your pond filtration unit is powered off and fully disconnected from the mains. Open the protective UVC housing, remove the old lamp by gently pulling the 4-pin connector, and slide the new 55W PLL bulb into the 2G11 socket until it clicks into place. Never touch the glass of the new bulb with bare fingers, as oils from your skin can create hot spots that shorten the lamp's lifespan; use a clean, dry cloth or gloves. Always verify that your UVC unit is compatible with 55W 2G11 bulbs before installation. To ensure safety, confirm that the housing is airtight and light-tight before powering it back on, as direct exposure to UV-C light must be avoided.
