When to Replace
UV lamps lose germicidal strength over time even if they keep glowing. Most manufacturers recommend changing the lamp every 12 months, or sooner if the system runs constantly. Waiting too long reduces protection and risks bacteria slipping through untreated.
Installation Notes
-
Switch off power and unplug the UV unit before opening.
-
Handle the lamp with clean gloves or a lint-free cloth to avoid fingerprints.
-
Slide out the old lamp and insert the new one, ensuring it clicks securely into place.
-
Reset the timer (if fitted) and check the lamp is operating correctly.
-
If unsure, contact a qualified plumber or technician for help.

Pro Tip
If your quartz sleeve looks cloudy or cracked during a lamp change, replace it at the same time. A clean sleeve ensures maximum UV output and keeps your system working at full strength
FAQs
1. How do I check if this lamp fits my system?
Look for the model number on your UV chamber. If it is a Greenway GAUV10S/SB, GUVL-10S, GUV-600S, UV Option 1 or 4 Deluxe, or Pure Water Products UVT5500SS, this lamp is compatible.
2. Can I keep using the lamp if it still lights up?
No. UV lamps lose germ-killing power before they stop glowing. Replace every 12 months for safe, bacteria-free water.
3. Does this include the quartz sleeve?
No. This is the lamp only. If the sleeve is cracked or scaled, replace it as well.
4. Do I need tools to change it?
No special tools are needed. Just power down, slide the lamp out, and fit the new one with gloves to avoid marking the glass.
5. How long does this lamp last?
On average, around 9,000 hours or one year of continuous use. Mark your calendar or set a reminder to change it on schedule.
