Pros
- 26 GPM at the full 40 mJ/cm² dose, enough for a farm, irrigation on the same line or a small business
- A UV sensor reads the actual dose and can drive a shutoff valve on low UV
- 1.5 in ports keep pressure loss low at high flow
Cons
- The 45 in chamber needs a lot of wall and room to pull the lamp
- 1.5 in ports mean reducers on most home plumbing
- The shutoff valve is an extra purchase
- A genuine S950RL-HO lamp costs about $185 on Amazon every year
- Not NSF certified

Viqua VH410M
#4 in Over 12 GPMFull review
The monitored version of Viqua’s large home unit, for well owners who want to know the dose is actually being delivered. Worth the premium over the plain VH410 if no one checks the water regularly.
