Luminor Blackcomb LB5-151
#2 in Up to 12 GPMFull review
A well built Canadian unit with an honest 12 GPM rating at the full dose, for a typical well home. Buy the LB6 version if you want a sensor from day one.

2.6/5
A dependable small home or cabin unit from the biggest name in residential UV, with a real controller warranty. Larger homes need the VH410 or a monitored system.

Pros
- Rated at the 40 mJ/cm² dose used for NSF Class A, so its flow figure is a conservative one
- Shows days left on the lamp and sounds an alarm if the lamp fails
- Covered 3 years on the controller and 10 on the chamber, longer than budget imports
- Short 15 in chamber fits a tight utility room
Cons
- No UV sensor, so a fouled sleeve or cloudy water can cut the dose without any warning
- At 7 GPM at the full dose it suits a small home; Viqua’s 9 GPM figure is at a lower dose
- A genuine S200RL-HO lamp costs about $135 on Amazon every year
- Not NSF certified; only the separate VH200-V version is, and only to Class B

HQUA OWS-12
#3 in Up to 12 GPMFull review
A bare bones budget UV for a cabin or a well that already passes bacteria tests. Too little is published to rely on it for a known problem.
Amazon $199.99$199.99
HQUA TWS-12
#5 in Up to 12 GPMFull review
A compact budget unit for a tight utility room, with cheap lamps. Like other budget units it tells you little about the dose.
