Description
The RQ-850 is a genuine Luminor replacement quartz sleeve for LUMINOR BLACKCOMB LB4-201, LB5-201, and LB6-201 UV systems. It's an authentic Luminor part, not an aftermarket substitute, so your system keeps performing the way it was tested and certified.
Fits these Luminor BLACKCOMB systems
All three models above share the same "-201" flow rating, rated at 21 GPM, and use the identical RQ-850.
Why a genuine Luminor sleeve matters
Luminor certifies its UV systems as a complete lamp, chamber, and sleeve unit. A non-Luminor sleeve can differ in wall thickness or quartz quality, reducing UV-C output reaching the water and affecting your warranty coverage.

Q&A
Q:
How do I know if I need to clean the sleeve or replace it?
A:
Clean it if it's scaled or lightly stained; replace it if it's chipped, cracked, or stays discolored after cleaning. Even with no visible damage, Luminor recommends replacing the sleeve every 24 months as routine maintenance, since UV-C transmission through quartz declines gradually with age.
Q:
Do I need to buy the lamp too, or can I just replace the sleeve?
A:
The RQ-850 is the sleeve only. If your lamp is also due, pair it with the [RL-850](https://espwaterproducts.com/products/luminor-rl-850-replacement-uv-lamp-for-lb4-201-lb5-201-lb6-201) lamp, or save by ordering the [RLQ-850](https://espwaterproducts.com/products/luminor-rlq-850-uv-lamp-and-sleeve-replacement-kit) kit, which bundles both.
Q:
Can I use a non-Luminor sleeve instead of the RQ-850?
A:
You can, but it's not recommended. Luminor certifies its systems as a complete lamp-chamber-sleeve unit, and a non-Luminor sleeve can differ in wall thickness or quartz quality, which reduces the UV-C dose reaching the water and can affect your warranty coverage.
Q:
Why does the sleeve need replacing on a different schedule than the lamp?
A:
The lamp is a wear part rated for 9,000 hours, so it's replaced on a fixed schedule (about every 12 months). The sleeve doesn't burn out the same way; it fouls from mineral scale and staining, which is why its replacement guidance is calendar-based (every 24 months) rather than hour-based.
Q:
Does the RQ-850 fit all three LB4-201, LB5-201, and LB6-201 systems the same way?
A:
Yes. All three run the same 21 GPM "-201" flow rating and use the identical chamber and sleeve; only the controller display differs between the 4.1, 5.1, and 6.1 models.
