I flicked through one of the reviews, and that par diagram you posted was over an empty tank. This is not very much light output at all.
It would work for a fowlr, but I don't know if you could keep any coral alive underneath that.

My tank is going to be fowlr for now. If I had two of those 48" over it would it be enough? I don't plan on getting too carried away with extravagant coral.

I believe they compare their LEDs to T5HOs. Not like the Radions comparing to 250W MH

If it's a fowlr than any amount of light is enough, so 1 would be enough if it looks bright enough.
If you do decide to add some corals, just account for new lighting.
