I just recently got my my EAGLETAC P100C2 and planned to use it for close work from 1 to 10 feet. Well this thing is so bright it actually hurt my eyess to use it that close. So I checked the threads on defusers and then set out to find something that would work. After a few failures with scotch tape and other things I found this at WALMART. Its contact paper used to line shelves. Good and sticky, defuses the beam perfect. Cost 6.00 for a HUGE ROLL. Easy to cut with scissors and isnt as easy to tear as scotch tape. It actually will stretch a little without deforming. Seems to work well with heat too. Ran the EAGLETAC for a solid hour on hi with no problem. Sorry no beam shots.
