Questions on air cooled bulbs

I'm new to the air cooled bulb setup, I've seen pic of air cooled bulbs with a inline fan to help suck the hot air. My question is does the intake fan has to blow air to cool down the bulb or does it have to suck the hot air the bulb produce or can one have both a intake fan blowing and a intake sucking lol . I just bought a 600watt sun tube reflector with bat wing for my closet and want to cool the shit out of it so it doesn't produce a lot of heat
Thanks guys for your comments

I assume you meant a cooltube reflctor, in which case just run tubing from outside of your room (or inside but outside works much better) to the reflector and then run another thing of tubing out the other end of the reflector and get an inline fan exhausting the air out of the room. you now have air running through tubes in your room cooling off the bulb and insuring that the air from the bulb never escapes into your grow room.

thanks Regrets now when you said run tubing outside your room that's to bring in fresh air to the tube? wouldn't it be better to have a in line fan on top of the cab sucking in fresh air from my bedroom into the cool tube and the exhaust blower into the scrubber?
now venting the hot air is it when it passes through the scrubber filter, just the smell is filter but the hot air still leaves the scrubber?
Also what CFM rating would be good to use with a 600 watt tube? thanks for replying

what you can do is have your scrubber hooked up in the room with the fan pulling air through the scrubber (hopefully kept up high to take out as much hot air as possible) then pushing the air through a tube that enters your lamp and have the other tube come out of the other hole in your lamp and push that air out into your bedroom. basically the higher cfm the better, but most scrubbers use a specific cfm the best so base it off of the scrubber you have.

when setting up a cool tube reflector you need to push fresh cool air from outside your room thru the hood and duct the outlet of the cool tube to outside the room and all the way to another area if possible so you dont heat the air in the room you are getting the intake air from .
there is no need to scrub this air because its never actually been in your room to get odor in it.
the reaon you want to push air instead of pull air is that you dont want to be sucking hot air accrossed the fan ... this could cause it to burn up prematurely.
here is a link to a diagram of the most effient way to cool a "cool tube" brand reflector that was kindly posted by Al B. Fuct

as you can see the cooling of the light is an independant system

do NOT pull hot air thru a carbon scrubber.
