Product Information
Full details
The Philips TUV PL-S 7W UV lamp is an ideal choice for pond owners and industrial facility managers who require reliable water clarification and microbial sterilization. This compact, 7-watt germicidal bulb excels at neutralizing green water algae and inactivating harmful bacteria and viruses through high-quality 253.7nm UV-C radiation, though users must be cautious as the emitted light is harmful to skin and eyes and requires shielded housing.

FAQs
Can I look directly at the bulb while it is on?
No. The UV-C light emitted by this bulb is extremely harmful to human eyes and skin. Never operate the bulb outside of an enclosed, shielded housing.
Why do I need to replace the bulb every 6 months?
While the lamp may continue to glow, the germicidal UV-C intensity drops significantly after about 6 months of use, reducing its ability to kill algae and bacteria.
Does this bulb kill fish or beneficial plants?
No. When used in a closed UVC filter, the UV radiation is contained within the unit. Only water-borne pathogens and algae passing directly through the chamber are affected.
What is the base type for this bulb?
This bulb uses a G23 base, which is a standard 2-pin fitting for compact fluorescent lamps.
Can I use this bulb for general lighting?
No. This is a germicidal UV-C lamp, not a standard light bulb. It is intended strictly for sterilization and clarification purposes.
Troubleshooting
Bulb does not light up
Check the power supply to the unit, ensure the bulb is securely seated in the G23 socket, or verify that the external ballast is functioning.
Pond water remains green
Check if the bulb is older than 6 months and replace if necessary. Additionally, ensure the quartz sleeve covering the bulb is free of limescale and algae deposits.
Bulb flickers during operation
Ensure the connection to the G23 socket is clean and free of corrosion. If the flickering persists, the integrated starter or the ballast may be failing.
Pros and Cons
Pros
- Highly effective at clearing green pond water
- Easy to install with a standard G23 base
- Compact form factor saves space in filter units
- Consistent UV-C output for reliable sterilization
Cons
- UV-C radiation is hazardous to skin and eyes
- Requires replacement every 6 months for maximum efficacy
- Must be used within specialized, light-tight equipment
Setup, Compatibility & Care
To install the bulb, ensure your UVC unit is completely disconnected from the power supply. Align the pins of the G23 base with the socket and press firmly until locked into place. Never touch the glass of the bulb with bare hands, as natural oils can reduce the bulb's lifespan; use a clean, dry cloth for handling.
Compatibility: This bulb is designed for fixtures specifically accepting the 7W PL-S configuration with a G23 base.
Maintenance: Even if the bulb appears to be functioning, it is strongly recommended to replace it every 6 months (approximately 4,000 to 5,000 hours of pond use). This interval ensures that the UV-C intensity remains high enough to provide effective sterilization, as the germicidal output degrades faster than the visible light output.
