I wasn't asking you that. I know YOU were comparing watts. No one else seems to get it.
I agree, given the same depth water, MH are FAR more intense no matter how great the reflectors on the T5s are. This is partly what I was saying.

This is EXACTLY what I mean! If you're using one of those 6 or 8 bulb T5 fixtures you're using up just as much power (or more) than if you were to use 250w or less MH, and you'd be getting LESS PAR with the T5s. Hence, MH are far more efficient. Those using 400w MH over 18" deep tanks ARE energy pigs...but I've seen a couple of tanks using 12 T5s side by side that had just as many watts, and try to tell me they aren't energy pigs too?
Of course you can keep just as brilliant SPS corals under T5s, but you're using at least as many watts as you would if you were using MH, so what's the point? Do you still think you're being energy-wise?
You guys need to learn what PAR is, and how to compare PAR watt for watt. Some of you really aren't getting it.
Between me and Steve, one of us is gonna break down and give the lecture...
