I run a Vertex Illumina SR260 48" over a 72" tank at the moment. I get great spread despite the size over the tank, very few dark spots, and the shimmer is perfect.
Though looking at my tank when it had T5's over it, to the eye - it definitely seems more pleasing. I've currently got them set to 25W/80B/80RB over 12 hours with a 2 hour ramp up/down.
The only down side to all of this, is I've had really painfully slow growth across the board. SPS? Forget about it.. and some corals completely hate it. I've had a wall hammer for 4 months that has yet to open. It's not dying, but it sure as hell isn't doing anything, despite it's placement. It still hasn't acclimated to the LED's it seems.
I think the way to go these days is an LED/T5 combo! Best of both worlds.
