Flowtech UV Lamp 10 Inch (6W) – Replacement UV-C Germicidal Bulb for RO Water Sterilizers
The Flowtech UV Lamp 10 Inch (6W) is a genuine replacement UV-C germicidal bulb for 10 inch UV water sterilizer housings — the exact type of lamp used inside Axtron's own UV Light Water Sterilizer 10 Inch, and compatible with most standard 10" housings using a single-ended 4-pin lamp base. This is the bulb only, not a complete sterilizer unit — designed for customers who already have a UV sterilizer housing installed and need to replace the lamp itself.
Why UV Lamps Need Regular Replacement
A UV-C germicidal lamp can keep glowing well past the point where it's still effective at disinfecting water. UV output strength degrades gradually with use, and manufacturers generally rate these lamps for about 8,000–9,000 hours of continuous operation — roughly one year of typical use. After that point, the lamp may look like it's working normally, but its UV-C output has dropped enough that it's no longer reliably killing bacteria and viruses passing through the sterilizer chamber. Replacing the lamp annually (or after its rated hours) is the only way to keep a UV sterilizer actually doing its job, rather than just running for show.
Key Features of Flowtech UV Lamp 10 Inch (6W)
- 6W UV-C Output — Low-pressure mercury vapor lamp producing germicidal UV-C light for water disinfection.
- 212mm Length — Sized for the internal lamp cavity of standard 10 inch UV sterilizer housings (the "10 inch" refers to the housing/chamber size the lamp is built for, not the bulb's own length).
- Single-Ended 4-Pin Base — Direct-fit connector matching standard 10" UV sterilizer sockets.
- CE Certified — Built to recognized international safety standards.
- Chemical-Free Water Disinfection — Destroys bacteria, viruses, and other microorganisms without adding chemicals or altering water taste.
A Note on Handling & Disposal
Like all fluorescent-type UV-C lamps, this bulb contains a small amount of mercury (marked with the "Hg" symbol on the glass) and carries a UV-C radiation warning — avoid direct eye or skin exposure while the lamp is powered, and dispose of the old lamp responsibly rather than in regular household trash, as indicated by the crossed-out bin symbol on the lamp.
Compatibility
This lamp is built for standard 10 inch UV sterilizer housings using a single-ended 4-pin base — including Axtron's own UV Light Water Sterilizer 10 Inch. If you're replacing a lamp in a different brand's 10" housing, confirm your housing uses the same 4-pin single-ended connector before ordering.
Applications
- Replacement Lamp for Domestic & Semi-Commercial RO Systems — Restoring full UV disinfection in an existing 10" sterilizer housing.
- Annual Maintenance — Scheduled lamp replacement as part of routine RO system servicing.
- Under-Sink & Countertop UV Sterilizer Units — Standard-fit replacement for compact UV disinfection stages.
Why Axtron?
Axtron Pakistan has supplied water filtration and RO plant components since 2005, with offices in Lahore, Multan, and Bahawalpur and a network of 500+ retailers nationwide.

Conclusion
If your RO system's UV sterilizer has been running for a year or more, don't assume it's still protecting your water just because the lamp is lit. The Flowtech UV Lamp 10 Inch (6W) is an affordable, direct-fit way to restore full UV-C disinfection strength to your existing 10" sterilizer housing.

12. FAQ Section (add via Rank Math's FAQ block for FAQPage schema)
Q1: Is this a complete UV sterilizer or just the lamp?
A1: Just the lamp. This is a replacement bulb for an existing 10 inch UV sterilizer housing — it doesn't include the stainless steel chamber or housing.
Q2: Will this fit my Axtron UV Light Water Sterilizer 10 Inch?
A2: Yes — this is the correct replacement lamp for that unit.
Q3: How often should I replace the UV lamp?
A3: About once a year, or after roughly 8,000–9,000 hours of use. The lamp may still glow after that point, but its disinfection strength drops significantly.
Q4: What base/connector does it use?
A4: A single-ended 4-pin base. If replacing a lamp in a non-Axtron housing, confirm your unit uses the same 4-pin connector.
Q5: Is this lamp safe to handle?
A5: Yes, when handled properly — avoid direct skin/eye exposure while powered, and dispose of the old lamp responsibly since it contains a small amount of mercury, standard for this lamp type.
Q6: Do you deliver this across Pakistan? A6: Yes — Axtron delivers nationwide, including Karachi, Lahore, Islamabad, Rawalpindi, Faisalabad, and Multan, with physical offices in Lahore, Multan, and Bahawalpur.
