Description
The RQ-999 is a genuine Luminor replacement quartz sleeve for LUMINOR BLACKCOMB LB4-151, LB5-151, and LB6-151 UV systems, plus their NSF Class A/B variants below. 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
- LB4-151
- LB5-151
- LB6-151
- LB5-151B (NSF Class B, non-monitored)
- LB6-151B (NSF Class B, non-monitored)
- LB6-151A (NSF Class A, monitored, includes UV sensor)
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), not a different sleeve. All six models above use the identical RQ-999.
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-999 fit the Class A and Class B versions of my system, or just the standard LB-151?
A:
It fits all of them. The A and B suffixes only mark the system's NSF/ANSI 55 monitoring class; the chamber and sleeve are identical across all six LB4/5/6-151 variants.
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 scratched, pitted, or stays 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:
Do I need to buy the lamp too, or can I just replace the sleeve?
A:
The RQ-999 is the sleeve only. If your lamp is also due, pair it with the [RL-999](https://espwaterproducts.com/products/luminor-rl-999-replacement-uv-lamp-for-lb4-151-lb5-151-lb6-151) lamp, or save by ordering the [RLQ-999](https://espwaterproducts.com/products/luminor-rlq-999-uv-lamp-and-sleeve-replacement-kit) kit, which bundles both.
Q:
Can I use a non-Luminor sleeve instead of the RQ-999?
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.
