high intensity, very low flow. The vendors don't help since they spec the maximum flow through their UV sterilizers but that's completely useless for eliminating real pathogens. You want to run down in the 200-300 gph rate if you're at or under 50W but they advertise 5000 gph capable...

That might be technically true - that the device can handle that flow rate. But it would serve no function at that rate at 50W. The lower the power, the slower the flow rate needs to be to make sure the UV has a chance to sterilize the water.
