Well, I have a home-made cool tube, and I used a Bake A Round...

I can't tell you the difference between cool tube and NO-cool tube because before the tube, I had a sealed hood.

But, those bulbs give off quite some heat... I think that the biggest "change" the cool tube makes to a grow setup, is in keeping the cooling air close around the bulbs, and away from the rest of the grow.

A sealed hood keeps the hot air separated, but a cool tube "forces" the air to come into contact with the bulbs.

It's pretty cool... hehehe....

But not cool to the touch... at least, not mine. But not a lot of "radiated" heat either...

Cool tubes are cool! Get some... get cool...
