Description
This replacement UV lamp keeps a Polaris UV-1C (pre-2018) or Trevoli UV-6 system delivering safe, bacteria-free water. It’s built to the exact specification these systems need, so there’s no compatibility guesswork.

- T5 4-pin even connection fits straight into the existing housing, with no adapters needed
- NZ stock is held locally for fast replacement when a system is due for its annual service
Why You Need It
UV lamps degrade steadily with use, and after 12 months of operation, output typically drops below the level needed to reliably neutralise bacteria, viruses, and protozoa, even though the lamp still glows and looks fine. A system running on a spent lamp can appear to be working normally while offering little real disinfection. Annual replacement on schedule, rather than waiting for a visible sign of failure, is what keeps water genuinely safe.
How to Replace Your UV Lamp
- Turn off the UV system and disconnect the power
- Turn off the water supply
- Allow the lamp to cool for at least 5 minutes
- Carefully remove the old lamp, avoiding contact with the glass with your bare hands
- Insert the new lamp and ensure the pins are fully seated
- Reassemble, restore the water supply, and power on
- Reset your system’s lamp timer if applicable
FAQs
How do I know if my Polaris UV-1C is the pre-2018 model that this lamp fits?
Check the OEM lamp code on your existing lamp or system documentation against GL10SE4P. If your system was installed or serviced after 2018, confirm the lamp code before ordering, as later models may use a different specification.
Does the lamp need to be replaced even if the water still looks and tastes fine?
Yes. UV disinfection doesn’t change how water looks or tastes, so there’s no visible warning sign when output drops. The only reliable way to know performance is holding up is by sticking to the 12-month replacement schedule.
Do I need to replace the glass sleeve at the same time as the lamp?
Not necessarily every time, but it’s worth checking for scaling or discolouration. A fouled sleeve blocks UV transmission even with a brand-new lamp, so if the sleeve looks cloudy, replace both together.
Can I install this lamp myself, or does it need a technician?
Most people can do this themselves. The lamp installs the same way as the original, and the process is generally not much different from changing a light bulb, just handled with clean hands and the system powered down first.
What’s the difference between the Polaris UV-1C fitting and the Trevoli UV-6 fitting?
Both use the same 212mm, 10W, T5 4-pin even lamp, so the same replacement lamp suits either system, despite the different OEM part naming.
Why avoid touching the glass with bare hands during installation?
Skin oils can create hot spots on the lamp’s surface, which shortens its lifespan or affects UV output. Handle it with a clean cloth or gloves instead.
