Description
Overview
When UV systems run every day, the lamps inside slowly lose their germ-killing strength even if they still glow. This 30W, 600mm T5 UV lamp is built as a direct replacement for the Greenway GAUV10S/SB model and a number of other compatible units. Swapping it out on schedule keeps the system working at full strength, making sure your water is safe from bacteria. The lamp has the same four-pin T5 connection found in many residential and light commercial UV sterilisers, so replacement is straightforward once you confirm the model.

When to Replace
A UV lamp may keep glowing long after it stops being effective. Most manufacturers recommend changing the lamp every 12 months. Old lamps give less UV output, which means bacteria and viruses may slip through untreated. Keeping a yearly cycle gives peace of mind that the water you are drinking is safe.
Installation Notes
-
Turn off power and unplug the unit before opening the UV chamber.
-
Wear gloves or use a lint-free cloth when handling the lamp. Oils or fingerprints on the glass reduce its performance.
-
Slide out the old lamp carefully and insert the new one until it clicks in securely.
-
Reset the lamp timer (if your system has one) and check that the unit powers up correctly.
-
If unsure, get a plumber or technician to carry out the replacement.
Important Reminder
This listing is for the UV lamp only, not the quartz sleeve or the full UV unit. If the quartz sleeve shows scale build-up, cloudiness, or cracks, it should be replaced at the same time to keep the steriliser working properly.
Pro Tip
Keep a spare lamp on hand. That way if the lamp fails unexpectedly, you are not left without UV protection while waiting for a replacement. Many tradies and homeowners change the lamp at the same time as their annual water system service.
FAQs
1. How do I know if this lamp fits my system?
Check the model on your UV chamber. If it is Greenway GAUV10S/SB, GUVL-10S, GUV-600S, UV Option 1 Deluxe, UV Option 4 Deluxe, or Pure Water Products UVT5500SS, this lamp is a match.
2. Can I use the lamp if it still glows?
Not recommended. A glowing lamp does not mean it is killing bacteria effectively. After about 12 months the output drops too low to disinfect water properly.
3. Is this product just the lamp?
Yes. This is the replacement lamp only. The quartz sleeve and other parts are sold separately. If your sleeve is dirty or cracked, replace that as well.
4. Do I need tools to replace the lamp?
No special tools are needed. Power off the unit, open the chamber, remove the old lamp, and slot in the new one. Gloves or a cloth are recommended to keep the glass clean.
5. How long does this lamp last?
Around 9,000 hours, which works out to about one year of continuous use. Replacing it annually keeps your system disinfecting at full strength.
