Hi Everyone, I just thought I'd share how I got my Cree's out of arctic alumina. I took a small precision screwdriver and using it like a chisel shaved off the alumina around the led. Then, I put the screwdriver and tapped it with the back of a small screwdriver all around the base of the LED being careful not to hit it too hard. I got 6 off a piece of aluminum, and only two sides of each LED were exposed. I only wound up chipping one of the PCB's, but all the LED's still work.
