Description
The RL-500A is a genuine Luminor replacement UV lamp and lamp key for LUMINOR RAINIER LR5-355 and LR6-355 light commercial UV water treatment systems, and their low-UVT "-50" 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 12,000 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 12,000 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-500A keeps your system performing the way it was certified. A non-Luminor lamp voids the system's certification and can affect your warranty coverage if a problem comes up later.
Fits these Luminor Rainier systems
- LR5-355
- LR6-355
- LR5-355-50 (low-UVT crossover)
- LR6-355-50 (low-UVT crossover)
The RL-500A runs on either 110V/60Hz or 230V/50-60Hz power, so the same lamp covers both electrical configurations. All four models above use the RL-500A.
Complete your replacement The RL-500A is the lamp only. For the full replacement:
- Luminor RQ-500 UV Quartz Sleeve, the quartz sleeve that houses the lamp. Replace every 24 months, or sooner if it's visibly scaled, cloudy, or damaged.

- Replace every 12 months or 12,000 hours of use
- Length: 19.7" (500mm)

Helpful Info & Downloads
Q:
How do I know if the RL-500A is the right lamp for my system?
A:
Check the model number on your system's nameplate. The RL-500A fits LR5-355, LR6-355, and their low-UVT "-50" variants. If your model has a "LB" or "LBH" prefix instead of "LR," you have a BLACKCOMB system and need a different lamp.
Q:
What's the difference between a Rainier system and a BLACKCOMB system?
A:
Rainier is Luminor's light commercial and industrial UV line, built for higher flow and heavier duty cycles than the residential BLACKCOMB lineup. The LR5-355 and LR6-355 are rated at 35 GPM, well above what a typical home needs, and are classified by Luminor under its commercial and industrial product category rather than residential.
Q:
What does the "-50" suffix mean on models like LR5-355-50?
A:
It marks a low-UVT crossover configuration, built for source water with reduced UV transmittance. Standard LR5-355 and LR6-355 systems are rated for 30 mJ/cm² at 95% UVT and 35 GPM; the "-50" variants are rated for the same dose at 50% UVT, with flow reduced to 14 GPM to deliver that dose in less clear water. They use the same RL-500A lamp as the standard systems.
Q:
The RQ-500 sleeve page lists "LR5-352, LR6-352" instead of "LR5-355, LR6-355." Is it still the right sleeve for my system?
A:
Yes. The RQ-500 is the quartz sleeve Luminor specifies for the LR5-355 and LR6-355 Rainier systems; the model numbers on that listing refer to the same sleeve part.
Q:
Will a non-Luminor replacement lamp work in my Rainier system?
A:
It may physically fit, but Luminor systems are 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.
