Luminor RL-850 Replacement UV Lamp for LB4-201, LB5-201, LB6-201
The RL-850 is a genuine Luminor replacement UV lamp and lamp key for LUMINOR BLACKCOMB LB4-201, LB5-201, and LB6-201 UV water treatment systems. 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 9,000 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 9,000 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-850 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.

Q:
How do I know if the RL-850 is the right lamp for my system?
A:
Check the model number on your system's nameplate. The RL-850 fits LB4-201, LB5-201, and LB6-201. If your model ends in a different number, like -101, -151, or -061, you need a different lamp.
Q:
Is a 21 GPM system (LB4-201, LB5-201, LB6-201) big enough for my house?
A:
Yes, for the vast majority of homes. As a sizing reference, ESP recommends at least 6 GPM for a 1-bathroom home, 9 GPM for 2 bathrooms, 12 GPM for 3, 15 GPM for 4, and 18 GPM for 5, and it's better to oversize than undersize. At 21 GPM, the LB4/LB5/LB6-201 covers the largest homes on that scale with room to spare. For flow needs beyond that (large commercial applications), contact ESP directly since those are sized on a case-by-case basis.
Q:
I installed a new RL-850 and now the system says "Lamp Incorrect." What's wrong?
A:
This alarm means the lamp key doesn't match what your chamber requires. Compare the part number on the lamp key to the silver label on the UV chamber. If they don't match, you have the wrong lamp; the RL-850 is for the standard-output LB4/LB5/LB6-201 systems listed above, and BLACKCOMB-HO systems use an entirely different model and lamp lineup. If the numbers do match and the alarm persists, contact Luminor support.
Q:
How do I reset the lamp timer after installing the RL-850?
A:
On a 4.1 controller (4-digit LED display), press and hold the front button until the display cycles through rSt3, rSt2, rSt1 and beeps. On a 5.1 controller (LCD display with lamp key), unplug the controller, remove the old lamp key, insert the new lamp's key, then plug it back in. Either way, the display should return to showing full lamp life remaining; if it doesn't, contact Luminor support.
Q:
Will a non-Luminor replacement lamp work in my BLACKCOMB 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.
