MH light in a small(er) space?

Does anyone have any experience with running something like a 400W MH light in a 6'W x 6'D x 5'H space? I am running a pile of CFLs right now but am looking at my options... I am worried about heat more than anything...

Something like this: Sun System 5 400W Metal Halide Enclosed Grow Light - Plantlighting Hydroponics



Thanks!

i use a 1000w (600HPS/400MH) in a space that is 24" x 46" x 75". i use a 170 CFM fan to exhaust the light and a 440 CFM to exhaust the room. in the winter it is fine - but i do have to watch it in the summer.

What kind of temps do you run near the plants?

yeah you will be fine just exhuast the grow room 400s dont get to hot.....Jmac
