Description
The RLQ-290 is a genuine Luminor UV lamp and sleeve kit for LUMINOR BLACKCOMB LB4-031, LB5-031, and LB6-031 UV water treatment systems, and their NSF Class A/B, LBV, and 12VDC variants below. The kit bundles the RL-290 UV lamp, RQ-290 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-290 lamp is rated for 9,000 hours of use, about 12 months of continuous operation, and Luminor recommends replacing it on that schedule to keep UV output where the system needs it. The RQ-290 sleeve typically lasts about 24 months before mineral scale starts cutting into UV output. For step-by-step swap instructions, see ESP Water's 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-290 and RQ-290 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.
LB6-031A (NSF Class A, monitored, includes UV sensor)
LBV-031
LB6-03-12V (12VDC power)
LB6-03A-12V (12VDC power, NSF Class A, monitored)
The A and B suffixes mark the system's NSF/ANSI 55 monitoring class, not a different lamp or sleeve, and the 12VDC models swap only the power supply for off-grid, RV, or marine use. All nine models above use the same RL-290 lamp and RQ-290 sleeve.
Includes Lamp Key (works for LUMINOR Branded Systems Only)
For all LUMINOR LB4-031, LB5-031, LB6-031 UV systems

More product information
Q:
What is the Luminor RLQ-290?
A:
It's a genuine Luminor replacement kit containing the RL-290 UV lamp, RQ-290 quartz sleeve, and a new lamp key, sized for LUMINOR BLACKCOMB LB4-031, LB5-031, and LB6-031 UV water treatment systems.
Q:
Does the RLQ-290 kit fit the LB5-03-12V or LB6-03-12V systems?
A:
Yes. The 12VDC models use the same UV chamber, lamp, and sleeve as the standard -031 line — only the power supply changes for off-grid, RV, or marine setups — so the RLQ-290 fits all of them.
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 9,000 hours (about 12 months), 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-290 or RQ-290 separately if only one needs replacing.
Q:
What does the "Lamp Expired" alarm on my Blackcomb controller mean?
A:
It means the lamp has reached the end of its rated life, or the timer wasn't reset after a lamp change. Replace the RL-290 lamp if it's due, then reset the countdown timer on the controller.
Q:
How do I reset the lamp timer after installing the lamp key from this kit?
A:
LB4-031/LB5-031/LB6-031 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-290 lamp, then plug it back in. The display should show 375 or 420 days depending on your system.
