Description
The RQ-210 is a genuine Luminor replacement quartz sleeve for LUMINOR BLACKCOMB LB4-021, LB5-021, and LB6-021 standard-output systems, and LUMINOR BLACKCOMB-HO LBH4-051, LBH5-051, and LBH6-051 high-output systems, plus their NSF Class A/B and vending variants below. It's an authentic Luminor part, not an aftermarket substitute, so your system keeps performing the way it was tested and certified.

Why the RQ-210 fits both product lines
The standard BLACKCOMB LB4/5/6-021 and the BLACKCOMB-HO LBH4/5/6-051 share the same chamber geometry, so both use the identical RQ-210 sleeve even though they take different lamps: the standard RL-210 or the High Output RL-210HO.
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:
Does the RQ-210 fit both my BLACKCOMB and BLACKCOMB-HO system?
A:
Yes. The RQ-210 is the correct sleeve for both the standard BLACKCOMB LB4/5/6-021 line and the BLACKCOMB-HO LBH4/5/6-051 line. They share the same chamber geometry, so one sleeve part number covers both, even though each line takes a different lamp (RL-210 or RL-210HO).
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/cloudy 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:
Why does the sleeve need replacing on a different schedule than the lamp?
A:
The lamp is a wear part rated for 9,000-10,000 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:
Can I use a non-Luminor sleeve instead of the RQ-210?
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:
Do I need the lamp too, or just the sleeve?
A:
The RQ-210 is the sleeve only. If your lamp is also due, pair it with the [RL-210](https://espwaterproducts.com/products/luminor-rl-210-replacement-uv-lamp-for-lbh-201-lb5-201-lb6-201) (standard) or [RL-210HO](https://espwaterproducts.com/products/luminor-rl-210ho-replacement-uv-lamp) (High Output) lamp, or save by ordering the [RLQ-210](https://espwaterproducts.com/products/luminor-rlq-210-uv-lamp-and-sleeve-kit-for-lb4-201-lb5-201-lb6-201) or [RLQ-210HO](https://espwaterproducts.com/products/luminor-rlq-210ho-uv-lamp-and-sleeve-kit-for-lbh4-201-lbh5-201-lbh6-201) kit, which bundles both.
