I made a 5 watt LED head light. The LED mounts at eye brow level between the eyes. I would like to cool it with a heat pipe curved towards the back of the head. Has anyone made their own? What did you use inside (Acetone?) What did you use for a wick?

Good luck with this one.
There are sealed methods of heat pumping away any excess heat you're getting bothered with but I dought they are cost effective.
The amount of heat generated by your application would be better dissipated by a heat sink and a air moving fan arrangment. This is assuming that you will be using quite a large size power supply to run your light.
Natural dissipation, a heat sink made from several #14 bare copper wires radiating outward would make your helmet? look like a porcupine. Paint em flat black and they would even work better.

Unless someone has developed a super-wick, a heat pipe is going to have to be installed with a slight pitch downward toward the hot end for the liquid to return. A device mounted on your head will not be practical unless you plan to hold your head still.
