Description
The Luminor RLQ-600HO UV Lamp and Sleeve Kit pairs a genuine RL-600HO UV lamp with its matched RQ-600 quartz sleeve and an installation key.
The RL-600HO lamp is rated for 10,000 hours of service (about 12 months of continuous operation), and Luminor recommends replacing the quartz sleeve 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 tested and certified as a complete unit — lamp, chamber, and sleeve together. Genuine Luminor parts keep your system performing the way it was certified; a non-Luminor lamp or sleeve can void that certification and affect your warranty coverage if an issue comes up later.
Fits these Luminor BLACKCOMB-HO systems
- LBH4-251
- LBH5-251
- LBH6-251
- LBH5-251B (NSF Class B, non-monitored)
- LBH6-251B (NSF Class B, non-monitored)
- LBH6-251A (NSF Class A, monitored, includes UV sensor)
- LBH4-251-50 (low-UVT crossover)
- LBH5-251-50 (low-UVT crossover)
- LBH6-251-50 (low-UVT crossover)
All nine models share the same "-251" rating (25 GPM) and use the identical RL-600HO lamp and RQ-600 sleeve. The A and B suffixes mark the system's NSF/ANSI 55 monitoring class, and "-50" marks a low-UVT crossover configuration — neither is a different lamp or sleeve.
- Includes RL-600HO and RQ-600
- Replace lamp every 12 months
- Replace sleeve every 24 months or as needed
Helpful Info & Downloads
Q:
What is the Luminor RLQ-600HO UV Lamp and Sleeve Kit?
A:
It's a matched replacement kit for Luminor BLACKCOMB-HO UV water treatment systems, including a genuine RL-600HO UV lamp, RQ-600 quartz sleeve, and installation key.
Q:
What does the "-50" suffix mean on some of these systems?
A:
It marks a low-UVT crossover configuration, built for source water with reduced UV transmittance (down to 50% instead of the standard 75% minimum). It uses the same RL-600HO lamp and RQ-600 sleeve as the standard systems — just tuned for different water conditions.
Q:
Can I order the lamp and sleeve separately instead of as a kit?
A:
Yes. If only one part needs replacing, the RL-600HO lamp and RQ-600 quartz sleeve are each available on their own. The RLQ-600HO kit is for when you're replacing both at once, which is the recommended approach since both wear parts age together.
Q:
Does this kit work with the LBH4/5/6-251-TOC systems?
A:
No — TOC variants use a different lamp, the RL-600HO-TOC, even though they share the same RQ-600 sleeve as the systems in this kit's fitment list. Contact us if you need to source a lamp for a TOC system.
Q:
My system alarm says "Low UV Intensity" — what does that mean?
A:
This alarm usually points to water quality outside spec, or a sleeve or sensor that needs cleaning. Start by cleaning and drying the quartz sleeve and sensor and reinstalling them — if the alarm clears, that was the cause. If it persists, a water quality test can identify whether pre-filtration is needed, and our support team can help if the issue continues.
