Luminor RLQ-420HO Lamp and Sleeve for LBH4-151, LBH5-151
The Luminor RLQ-420HO UV Lamp and Sleeve Kit pairs a genuine RL-420HO UV lamp with its matched RQ-420 quartz sleeve and an installation key.
The RL-420HO lamp is rated for up to 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.

Q:
What is the Luminor RLQ-420HO UV Lamp and Sleeve Kit?
A:
It's a matched replacement kit for Luminor BLACKCOMB-HO UV water treatment systems, including a genuine RL-420HO UV lamp, RQ-420 quartz sleeve, and installation key.
Q:
Why does this kit fit so many different system models?
A:
The RL-420HO lamp and RQ-420 sleeve are used across four separate Luminor product families that share the same chamber size — standard BLACKCOMB-HO -151 systems, low-UVT "-50" crossover models, rack-mounted Z-series systems, and Contractor Series systems — 22 model numbers in total, all using these identical parts.
Q:
Can I order the lamp and sleeve separately instead of as a kit?
A:
Yes. If only one part needs replacing, the RL-420HO lamp and RQ-420 quartz sleeve are each available on their own. The RLQ-420HO kit is for when you're replacing both at once, which is the recommended approach since both wear parts age together.
Q:
How do I reset the lamp timer after installing this kit?
A:
On a 5.1 controller (the type that uses a lamp key), unplug the controller, remove the old lamp key, insert the new lamp key that comes with the RL-420HO, then plug the controller back in — the display should show 375 or 420 days. Other controller types reset with a button-hold sequence instead; see our how to replace a UV lamp guide for the full steps.
