Let's get that quoted real quick.

I use a 600 in a 5' x 5' area and my hood isn't the largest horizontal reflector either.
seriously? that statement is ridiculous.
why if a 600w produces 92000 lumens and you split it between 25 sq foot you get 3680 lumensseriously? that statement is ridiculous.

now surely you are aware of cfls that produce 4000 lumens?
what i'm saying is that a 600w in that space is as useless as a 4000w cfl over every sq foot

No shit?..... awesome light distribution w/ 2 x 600w in a 4' x 4' area? Who'd uh thought?
I usually keep the lamp about 2 feet above the canopy

I'm concerned that I just won't be able to pull off a 1kW hps because of the heat and the circuit breakers max amps in the room I'm using.
If you can't get the 1K, you should go with a 600. It's 200 watts less (watts = heat) than 2 x 400, but just as much light.
You also have to factor in the price of an extra ballast, cordset and/or reflector, a bigger fan to handle the extra heat, and possibly a more powerful air-conditioner. I'd rather spend a little extra for a bigger lamp once a year.
That's why we are here not one person can think of everything. I still think I'd go with the 1000 watt over the (2) 400's with that in mind.You also have to factor in the price of an extra ballast, cordset and/or reflector, a bigger fan to handle the extra heat, and possibly a more powerful air-conditioner.

I'm starting to agree that 600W seems to be my only option.No doubt.
I am already running an inline duct fan + two carbon scubbers with fans on the other end with a 400W HPS. I'm exhausting out of two vent holes. The temps currently don't go above 78 degrees F. You really think the cool tube makes that much differences even with proper ventilation? The reason I ask is because I feel like the big trade off is going to be the plants along the outside of the tent; where as with the Sunsoaker 4x4 reflector, it would have reached them better than the cool tube. What do you think?
If you'd like to go with the 1000 watter you could run a cool tube and just use inside air, pull it in one side and out the other, you should be fine. Don't go thinking you are going to increase you inside temperature to that of the sun, they run hot but many people seem to get the impression that HID bulbs run hotter than they actually do.I'm starting to agree that 600W seems to be my only option.
As much as I'd like to go 1000W, without running exhaust outside and having an intake bringing in cool exhuast... I see problems on the horizon. With my grow tent the best I can do is use my room air conditioner (which isnt even that big) and vent air outside the tent into the room the tent is in.
Any last thoughts?
Thank you everyone!
If you can manage to dump the heat in front of the air-conditioner, you might not need an air-cooled reflector. I would suggest you check the temps with whatever reflector you're using for the 400 and go by that before you buy anything else. You'll have decent vertical space and the carbon extractor might be enough just to get the heat out of the tent and through the A/C.
