UV Lamp compatible with RL-40/867T5 for Wyckomar UV700 & Trevoli UV-30 Sterilisers

This replacement UV lamp is built to fit Wyckomar UV700 and Trevoli UV-30 steriliser systems. It delivers the same reliable UV-C output as the original RL-40/867T5 model, keeping bacteria and microorganisms out of your drinking water. The lamp measures 867mm in length and runs at 40 watts, giving solid, even performance across its full operating life. It’s the right choice for yearly system maintenance or whenever your old lamp’s glow starts to dull.

Key features

• Direct replacement fit: Built to match Wyckomar RL-40/867T5 and Trevoli UV-30 units exactly, with the same 4-pin T5 even connection. It slides in easily without any adjustments or adapters needed.
  

• Consistent UV performance: Produces a steady germicidal output to support the system’s ongoing water protection. Ideal for homes using UV as the main water treatment step.
  

• Durable and well-made: The lamp tube is designed to handle regular heating and cooling cycles without flickering or cracking, even under continuous operation.
  

• Simple changeover: No tools, sealants, or special fittings required. Just disconnect power, swap it out by hand, and you’re sorted.
  

• System safe: Works perfectly with your existing quartz sleeve and ballast when they’re clean and in good working order.
  

Where to use it

You’ll find this lamp used across a range of household and light commercial systems, especially in setups that rely on UV disinfection as a final treatment stage. Common installs include:

• Wyckomar UV700 systems used for small-scale domestic or commercial filtration.
  

• Trevoli UV-30 systems, rated as 30W compatible but still suited for this lamp type.
  

• Any other UV unit that specifies an 867mm, 40W, T5 4-pin even lamp.
  

When to replace

Swap your UV lamp roughly every 12 months of steady use. The lamp might keep glowing for longer, but the ultraviolet intensity starts to fade, and that’s what does the actual disinfection. Once that output drops, bacteria can start slipping through. Keeping a regular replacement cycle keeps your system doing its job properly and your water safe.

Installation notes

1. Turn off the power and unplug the system fully before touching the UV chamber.
   

2. Remove the old lamp carefully. Avoid twisting too hard or touching the glass, as fingerprints can mark the surface.
   

3. Insert the new lamp until it locks into place, making sure the pins line up with the connector.
   

4. Reset timers or counters if your system has them, then switch it on and check the glow through the indicator window before sealing it back up.
   

5. Check the quartz sleeve for any signs of cloudiness or scaling while you’re in there; it’s easier to sort now than later.

Pro tip

If your UV system runs around the clock, consider noting your lamp change date somewhere near the unit. That way, you’ll know when your next swap is due without guessing. It’s a small thing that helps you keep on top of maintenance and ensures the system keeps working as it should.

FAQs

1. How do I know this lamp fits my system?
Check your model label or manual. If your system lists Wyckomar UV700, Trevoli UV-30, or RL-40/867T5 as the lamp type, this is the right fit.

2. Can I keep using the old lamp if it’s still glowing?
You can, but it won’t disinfect properly once the UV strength fades. Always replace every 12 months to keep your water safe.

3. Do I need to change the quartz sleeve too?
Not always. If it’s clean and clear, you can keep using it. If it’s cloudy, cracked, or scaled, replace it at the same time for best performance.

4. Is this lamp difficult to install?
No, it’s a simple job. Unplug the unit, remove the old lamp, slide in the new one, and reset the system timer if it has one. No tools or plumber needed.

5. How long does the new lamp last?
On average, about 9,000 hours, which equals roughly one year of continuous operation. After that, replace it to maintain UV strength.
