At 24", par on the Sat + is at 58% of what it is at 12" (21 @ 24" vs 36 @ 12")
At 24", par on the Ray 2 is at 41% of what it is at 12" (36 @ 24" vs 87 @ 12")
As you see, the Ray 2 drops off in PAR faster than the Sat + does. However, the Ray 2 still has a lot more PAR at any level. For me, the Sat + would not be enough PAR for my plants. I'd need 2 of them, and that's a pretty big price difference.
