Description
The RLQ-210 is a genuine Luminor UV lamp and sleeve kit for LUMINOR BLACKCOMB LB4-021, LB5-021, and LB6-021 UV water treatment systems, and their NSF Class A/B and LBV variants below. The kit bundles the RL-210 UV lamp, RQ-210 quartz sleeve, and a lamp key together — both parts are authentic Luminor components, not aftermarket substitutes, so it drops in and treats water the way your system was originally tested and certified to perform.
The RL-210 lamp is rated for 9,000 hours of use, and Luminor recommends replacing it every 12 months or after 9,000 hours, whichever comes first, to keep UV output where the system needs it. The RQ-210 sleeve typically lasts about 24 months before mineral scale starts cutting into UV output. For step-by-step swap instructions, see How to Change Out Your UV Bulb guide, or How to Clean a UV Sleeve if you want to stretch the sleeve's service life between replacements.
Why a genuine Luminor lamp and sleeve kit matters
Luminor tests and certifies its UV systems as a complete unit: lamp, chamber, and sleeve together. Replacing both at once with genuine RL-210 and RQ-210 parts keeps your system performing the way it was certified. A non-Luminor lamp or sleeve voids the system's NSF/ANSI 55 certification and can affect your warranty coverage if a problem comes up later.

Helpful Info & Downloads
Q:
What is the Luminor RLQ-210?
A:
It's a genuine Luminor replacement kit containing the RL-210 UV lamp, RQ-210 quartz sleeve, and a new lamp key, sized for LUMINOR BLACKCOMB LB4-021, LB5-021, and LB6-021 UV water treatment systems.
Q:
Is the lamp in this kit the same thing as a UV bulb?
A:
Yes. Luminor and ESP call it a "lamp," but it's the same part many customers search for as a "UV bulb" — "luminor uv bulb replacement" and "uv bulb replacement" are both real searches that land on the RL-210 page. The RL-210 in this kit is a plug-in UV lamp, not a screw-in household bulb.
Q:
Should I replace the lamp and sleeve together, or only when each wears out?
A:
They're on different clocks: the lamp is rated for 10,000 hours, and Luminor recommends replacing it every 12 months or after 9,000 hours, whichever comes first, while the sleeve typically lasts about 24 months. The kit is convenient when both are due or you're unsure of your sleeve's condition; buy the RL-210 or RQ-210 separately if only one needs replacing.
Q:
What does a "Lamp Failure" alarm on my Blackcomb controller mean?
A:
It means the controller can no longer light the UV lamp. Unplug the system for at least 3 minutes, confirm the lamp connector is fully seated, and restart it. If the alarm persists, replace the lamp — the RL-210 in this kit is the correct genuine replacement for LB4-021, LB5-021, and LB6-021.
Q:
How do I reset the lamp timer after installing the lamp key from this kit?
A:
LB4-021, LB5-021, and LB6-021 use the 5.1 controller with a lamp key: unplug the controller, remove the old lamp key, insert the new key that comes with the RL-210 lamp, then plug it back in. The display should show 375 or 420 days depending on your system.
