Description
The Luminor RLQ-420 UV Lamp and Sleeve Kit pairs a genuine RL-420 UV lamp with its matched RQ-420 quartz sleeve and an installation key, so you get both wear parts in one order instead of tracking them down separately.
The RL-420 lamp is rated for 9,000 hours of service, and the quartz sleeve is recommended for replacement every 24 months. Replacing both together keeps UV output consistent and takes the guesswork out of maintenance timing. For step-by-step instructions, see our guides on how to replace a UV lamp and how to clean a UV sleeve.
Why a genuine Luminor lamp and sleeve kit matters
Luminor's UV water treatment systems are built and calibrated around genuine lamp and sleeve specifications. Using OEM parts helps keep UV output and system monitoring accurate, and avoids the fit or performance issues that can come with off-brand substitutes.

All listed systems are rated for 8 GPM. The Z1, Z2, Z12, and R1 suffixes identify the specific BLACKCOMB Z-series or Contractor Series model — check the label on your system's chamber or control box if you're not sure which one you have.
Need just one part instead of the full kit?
If your sleeve is still in good shape, the RL-420 lamp is available on its own. If only the sleeve needs replacing, the RQ-420 quartz sleeve is available separately too.

Q&A
Q:
What is the Luminor RLQ-420 UV Lamp and Sleeve Kit?
A:
It's a matched replacement kit for Luminor BLACKCOMB UV water treatment systems, including a genuine RL-420 UV lamp, RQ-420 quartz sleeve, and installation key — everything needed to replace both wear parts in one order.
Q:
Is a UV bulb the same thing as a UV lamp?
A:
Yes. "UV bulb" and "UV lamp" refer to the same part — the RL-420 is the UV lamp (sometimes called a UV bulb) included in this kit.
Q:
What do the Z1, Z2, Z12, and R1 suffixes mean on my Luminor system?
A:
These suffixes identify the specific BLACKCOMB Z-series or Contractor Series system model. If you're not sure which one you have, check the model label on your system's chamber or control box, or contact our team for help confirming compatibility.
Q:
Can I order the lamp and sleeve separately instead of as a kit?
A:
Yes. If only one part needs replacing, the RL-420 lamp and RQ-420 quartz sleeve are each available on their own. The RLQ-420 kit is for when you're replacing both at once, which is the recommended approach since both wear parts age together.
Q:
My system alarm says "Lamp Incorrect" — what does that mean?
A:
It means the installed lamp doesn't match what the system expects. Compare the part number on the lamp key to the label on the chamber — if they don't match, install the correct lamp. If the numbers do match and the alarm continues, contact support for further assistance.
