Sorry for the confusion ,lol, i was giving you a link to the c6 flashlight
there are quite a few people here who sell c3 heatsinks, take jayrob as an example and (i think) moh sells them aswel if you send him the host so he can measure the dimensions and make it a perfect fit.
I just came upon these as left overs from a group buy. It's not productive for me to make sinks for this host because there is jsut too many people already doing it. Radiant sells the aluminum one for this host for $15.
I'm not sure why i still have these last few left.....considering i'm selling them for cheaper than i bought them for.
