thanks for those close ups. is that just a high speed fan that u have on the one side. i think i have the same one. its got 3 settings on it and tilts right? just blows air through the bulb and out the ducting i presume. looks like i have what my cool tube is going to look like!
The fan you see in the pictures is for circulation, I just didn't have enough floor space, so I had to mount it somewhere out of the way. On the outside of my box, there is a pc fan pulling air through the ducting and cool tube.
