i dont think that you will have much of a heat issue with a 400 i just went through a whole cycle in a 4x4x8 cab. bulb in the middle and fan blowing straight up on the bulb and and the highest i temps i had were 80 then again my lights go on at night and it was a mild winter too! if you have a cool tube i think you will be quite ok as far as how close can the light go put your hand close to the bulb or cool tube while its set up if after a min of holding it there you hand feels hot then thats too close (picked it up off one of the posts here)and has always worked for me.

sure you needed the 6 inch when i went to the grow shop and told them my room is 4x5x8 they said the 4inch was gonna be WAY more then enough.... so if your room is big enough for a 6 inch might need a bigger light i know i prob should of got the 600 ='/ but one day it can just be my veg light =D

My closet it 4x4x6...haha...maybe a bit overkill...but i don't mind. I'll get a fan controller and keep the temps perfect. Thanks for the advice though man. It would have been way cheaper to go with the 4" probably...oh well.

same here, 1 x 250 watt hps 1 x 400 hps, 1 x 4inch inline fan 1 x 5inch inline fan, 4 x 3 x 3 ft cab. your problem is keeping the room cool, i run mine nights but still reckon i may have to drop it to just the 400 in the summer, i keep my cab close to open window.

Yeah man...i just got the fan so I was testing the temps just to be sure...they're staying between 80-83. A bit warm...but it'll be ok for now I'm thinking.
The lights about 8" away from the tops now.

Whats the wattage on that light your using?
Just curious because I just got one of them bake around tubes and I'm gonna be making my own diy cool tube. I got a 400 watt in a 3x3x8 closet now and with the outside temps on the rise my room is hitting 90 degrees. So I'm hoping it will do better than what your getting @ 80-83 degrees.
Peace.
Edit. duh I forgot I was on the 400 watt club thread. lol

it's a 400 watt. The temps without the fan were like 90-95 with my door closed.
