Description
The Luminor RLQ-500A UV Lamp and Sleeve Kit pairs a genuine RL-500A UV lamp with its matched RQ-500 quartz sleeve and an installation key, for Luminor's RAINIER light commercial line.
The RL-500A lamp is rated for 12,000 hours of service (about 12 months of continuous operation), and Luminor recommends replacing the quartz sleeve every 24 months, or sooner if it's visibly scaled, cloudy, scratched, or pitted. 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 RAINIER systems
- LR5-355
- LR6-355
- LR5-355-50 (low-UVT crossover)
- LR6-355-50 (low-UVT crossover)
All four models use the identical RL-500A lamp and RQ-500 sleeve. The RL-500A runs on either 110V/60Hz or 230V/50-60Hz power, so the same lamp covers both electrical configurations.
- Includes RL-500A and RQ-500
- Replace lamp every 12 months
- Replace sleeve every 24 months or as needed

Q:
What is the Luminor RLQ-500A UV Lamp and Sleeve Kit?
A:
It's a matched replacement kit for Luminor's RAINIER line — light commercial UV water treatment systems, distinct from Luminor's residential BLACKCOMB line. It includes a genuine RL-500A UV lamp, RQ-500 quartz sleeve, and installation key.
Q:
Does this lamp work on both 110V and 230V systems?
A:
Yes. The RL-500A runs on either 110V/60Hz or 230V/50-60Hz power, so the same lamp covers both electrical configurations — you don't need a different lamp for each.
Q:
Is a UV bulb the same thing as the RL-500A lamp?
A:
Yes. "UV bulb" and "UV lamp" refer to the same part — the RL-500A is the UV lamp (sometimes called a UV bulb) included in this kit.
Q:
Why does the sleeve need replacing if it's not worn out like the lamp?
A:
Unlike the lamp, the RQ-500 quartz sleeve doesn't burn out on a fixed schedule — instead, mineral scale and staining build up on its surface over time, gradually blocking UV-C transmission even if the lamp inside is new. Annual cleaning can restore clarity for a while, but once a sleeve is scratched, pitted, or stays cloudy after cleaning, it needs replacing rather than cleaning again.
Q:
Can I order the lamp and sleeve separately instead of as a kit?
A:
Yes. If only one part needs replacing, the RL-500A lamp and RQ-500 quartz sleeve are each available on their own. The RLQ-500A kit is for when you're replacing both at once, which is the recommended approach since both wear parts age together.
