Thanks for the replies everyone, and instead of getting an inline fan I ended up buying a 4" high velocity fan............and it works GREAT........paid 5 bucks for it (on sale from 11.99..ooohhh). After running my light for almost 6 hours i could grab ahold of my tube and barely feel any heat except for a small area around the tip of the bulb. I was moving my light up and down and letting it sit for an hour at a time to see if the bending would have much effect on it as well......there was no notable loss in air movement and the temp stayed the same..... i ended up buying 5 of the fans just in case, i will be using one as an intake fan on the back of the cab and one for the tube.........3 extra's incase something burns out

Fan for cool tube I just made my first pyrex cool tube for my 250 hps, i got 4" x 36" ducting (including the tube itself) and i was thinking about getting one of these fans, or something similar. http://www.bghydro.com/BGH/Itemdesc.asp?ic=AEFSC04&eq=&Tp= Does anyone think i'll need more?? I don't have lots of money for a blower so that is out of the question, and also if this is enough should I have it sucking the warm air out or blowing air in?? Rating: 5
