Description
The RL-950HO is a genuine Luminor replacement UV lamp and lamp key for LUMINOR BLACKCOMB-HO LBH4-401, LBH5-401, and LBH6-401 High Output UV water treatment systems, and their NSF Class A/B and low-UVT crossover variants listed below. It is an authentic Luminor part, not a compatible aftermarket substitute, so it drops in and treats water the way your system was originally tested and certified to perform.
The lamp is rated for 10,000 hours of use, about 12 months of continuous operation. UV-C output weakens gradually over the lamp's life, so Luminor recommends replacing it every 12 months or after 10,000 hours, whichever comes first, to keep UV output where the system needs it.
Why a genuine Luminor lamp matters
Luminor tests and certifies its UV systems as a complete unit: lamp, chamber, and sleeve together. An authentic RL-950HO keeps your system performing the way it was certified. A non-Luminor lamp voids the system's NSF/ANSI 55 certification and can affect your warranty coverage if a problem comes up later.
Fits these Luminor BLACKCOMB-HO systems
- LBH4-401
- LBH5-401
- LBH6-401
- LBH5-401B (NSF Class B, non-monitored)
- LBH6-401B (NSF Class B, non-monitored)
- LBH6-401A (NSF Class A, monitored, includes UV sensor)
- LBH4-401-50 (low-UVT crossover)
- LBH5-401-50 (low-UVT crossover)
- LBH6-401-50 (low-UVT crossover)
The A and B suffixes mark the system's NSF/ANSI 55 monitoring class (A is monitored with a UV sensor, B is non-monitored), and the "-50" suffix marks a low-UVT crossover configuration for source water with reduced UV transmittance, not a different lamp. All nine models above share the same "-401" High Output rating, at 40 GPM, and use the RL-950HO.
Complete your replacement The RL-950HO is the lamp only. For the full replacement:
- Luminor RQ-950 UV Quartz Sleeve, the quartz sleeve that houses the lamp. Replace every 24 months, or sooner if it's visibly scaled, cloudy, or damaged.
- Luminor RLQ-950HO UV Lamp and Sleeve Kit, which bundles the RL-950HO lamp, RQ-950 sleeve, and lamp key together for LBH4-401, LBH5-401, and LBH6-401.

Q&A
Q:
How do I know if the RL-950HO is the right lamp for my system?
A:
Check the model number on your system's nameplate. The RL-950HO fits any Luminor BLACKCOMB-HO system ending in "-401": LBH4-401, LBH5-401, LBH6-401, LBH5-401B, LBH6-401B, LBH6-401A, and the low-UVT "-50" crossover models. If your model ends in a different number, like -251 or -151, you need a different lamp.
Q:
My system's nameplate says LBH4-402 instead of LBH4-401. Is the RL-950HO still the right lamp?
A:
Yes. The "-401" and "-402" model numbers are the same 40 GPM High Output system, just built for different electrical service: "-401" models run on 110V and "-402" models run on 230V. Both use the identical RL-950HO lamp and RQ-950 sleeve.
Q:
What does the "-50" suffix mean on models like LBH5-401-50?
A:
It marks a low-UVT crossover configuration, built for source water with reduced UV transmittance (rated to treat water at 50% UVT rather than the standard 75% minimum). These units serve water with more organic material or color, but they use the same RL-950HO lamp as the standard "-401" systems.
Q:
Is the 40 GPM BLACKCOMB-HO tier (LBH4-401, LBH5-401, LBH6-401) overkill for a home, or is it meant for commercial use?
A:
At 40 GPM, this is Luminor's largest standard BLACKCOMB-HO flow tier, well beyond what a typical household needs; ESP's sizing guide tops out residential recommendations around 18-21 GPM for a 5-plus bathroom home. The 40 GPM "-401" systems are built for large estates, agricultural operations, and light commercial sites with correspondingly higher peak water demand. If your home doesn't need that much throughput, the 25 GPM LBH4/5/6-251 tier (RL-600HO lamp) is a better fit.
Q:
What does a "Lamp Failure" alarm mean?
A:
It means the controller can't light the lamp. Unplug the system for at least 3 minutes, check that the lamp connector is fully seated, then plug it back in. If the alarm continues, replace the lamp. If a new lamp doesn't clear it, the controller itself may need service.
Q:
Will a non-Luminor replacement lamp work in my BLACKCOMB-HO system?
A:
It may physically fit, but Luminor systems are NSF/ANSI 55 certified as a complete lamp-and-system unit. A non-Luminor lamp voids that certification and can affect your warranty if an issue comes up.
