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
