I met with the creator of Tuffleye (the main competitor to CCG) and they are about to release a new pen sized light that is 3x as bright as the original. It's supposed to sell for about $30.
I really like Tuffleye and CCG may work the same, but they say you have to use their light. Not sure that's true since I have a dentist's light that is pretty generic and it cures about anything of that nature.
Here's a hint: if you are putting one of these products on fibers, make sure you get some IN the fibers first and harden them before you put some around the fibers. Trapping air in the fibers will make the fly more bouyant than expected.
