Luminor RL-600HO Replacement UV Lamp for LBH4-251, LBH5-251, LBH6-251
Luminor RL-600HO Replacement UV Lamp for LBH4-251, LBH5-251, LBH6-251
Description
The RL-600HO is a genuine Luminor replacement UV lamp and lamp key for LUMINOR BLACKCOMB-HO LBH4-251, LBH5-251, and LBH6-251 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-600HO 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
- LBH4-251
- 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)
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 "-251" High Output rating, at 25 GPM, and use the RL-600HO.
Complete your replacement The RL-600HO is the lamp only. ESP sells the RQ-600 quartz sleeve bundled with the lamp rather than as a standalone item, so for the full replacement:
- Luminor RLQ-600HO UV Lamp and Sleeve Kit, which bundles the RL-600HO lamp, RQ-600 quartz sleeve, and lamp key together for LBH4-251, LBH5-251, and LBH6-251. Replace the sleeve every 24 months, or sooner if it's visibly scaled, cloudy, or damaged.
- Replace every 12 months or 10,000 hours of use
- Length: 23.6" (600mm)
- Power: 67 Watts
Helpful Info & Downloads
Q:
How do I know if the RL-600HO is the right lamp for my system?
A:
Check the model number on your system's nameplate. The RL-600HO fits any Luminor BLACKCOMB-HO system ending in "-251": LBH4-251, LBH5-251, LBH6-251, LBH5-251B, LBH6-251B, LBH6-251A, and the low-UVT "-50" crossover models. If your model ends in a different number, like -101 or -151, you need a different lamp.
Q:
Can I buy just the RQ-600 quartz sleeve without the lamp?
A:
Not as a standalone item through ESP; the RQ-600 sleeve for the 25 GPM "-251" systems is currently only sold bundled with the lamp in the RLQ-600HO kit. If your sleeve is due for replacement but your lamp still has life left, the kit is still the way to get a genuine RQ-600.
Q:
What does the "-50" suffix mean on models like LBH5-251-50?
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-600HO lamp as the standard "-251" systems.
Q:
How does the 25 GPM BLACKCOMB-HO (LBH4-251, LBH5-251, LBH6-251) compare to the 21 GPM standard BLACKCOMB system?
A:
Both are sized for the largest homes, but the 25 GPM High Output tier is built for households or light commercial sites that need more throughput than the standard-output 21 GPM LB4/LB5/LB6-201 systems (RL-850 lamp) provide, using LP-HO coated lamps designed to hold their UV dose steadily across the full rated life. Water quality requirements are the same either way: at least 75% UVT for the standard "-251" models, or 50% for the "-50" low-UVT variants.
Q:
My system is showing a "Lamp Expired" alarm. What does that mean?
A:
It means the lamp has reached the end of its rated life, or a new lamp was installed but the countdown timer on the controller was never reset. Luminor's guidance is that water may not be adequately treated once a lamp has expired, so replace the lamp and reset the timer as soon as possible. Holding the controller button for 5 seconds defers the alarm for 7 days, up to three times, but this doesn't restore UV treatment in the meantime.
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.
