As i posted before mine is up and running heat sinked in a 1.5x 1.5x by 1 foot aluminum block.
i know a whole foot long i have yet to cut it to size but just set it in there to see the heat dissipation of it and it works great just a tad bit large....
Light out the window and the clouds said hello, caught fire and fell to the ground so now i have fog to play with!@!
I cant wait to hear someone drive this at 2watts and have it live. that would be one beam...
