So just today i recieved my first set of blue cree emitters.... I immediatly opened the package and pulled one of these little suckers out and hooked it up to my powersupply
My first reaction was "this sucks". I really dont see them being any brighter than the luxeon emitters I was buying. These crees are supposed to put out at least 30lm at 350 ma. The luxeon were supposed to put out 30 lm at 700ma. So I naturally thought at 700ma the cree would blow the luxeon away. not so much. I havent had a chance to set them up side by side. I plan on doing that tonight. I dont expect much of a difference though.
My next thoughts are a little better. The cree didnt seem to get nearly as hot as the luxeon. This is a great advantage to me.
have you all had the same experience with the crees not getting as hot. If for no other reason the heat issue may be a reason to keep using the crees. However if not then back to the luxeon I go. The luxeon are cheaper and easier to get.
