Light mover in a hydrohut???

Hey guys, been doing some pretty serious research on here, and first off, I love y'all.
Secondly, to all those with Hydrohuts: Who has a light mover in there? I've got the 4x4x7, and thinking about a 3-foot track for a light mover. Does this make sense? I guess I'd have to move the racks they put in there for the blower and filter, but otherwise, would this work?
I was considering a 1000w hps, but I'm a little reluctant as this would tax my 15amp circuit quite a bit, and create heat issues. My thinking was that if I could unleash a mover in there and gain the extra 20% or whatever more efficiency on a 600-watter, it would be the next best thing.
Suggestions?

You don't need a light mover. I have a 600 watt in a 4x4 and it works great. I could maybe even put a 400 watt in there. (400 can fill 4x4feet). 1000 would get too hot. You could do it but it would be kinda overkill.

how many plants can you cram into one of those babies? sog style.
