hey guys,
I'm finishing up the design on my CNC bike light, but i need one piece of information so i can set up tolerances accordingly. so, does anyone know the thickness of the MCPCB star the cree XR-E's are mounted on? specifically the ones that cutter sells, if that makes a difference. i just need thickness and tolerance if you have it.

also, i remember seeing something about the stars having poor heat transferring ability. has this problem been resolved? will i be fine using stars at 1A, or should i just mount the emitter straight onto the housing.

thanks,
bryan

Just shy of 0.082in. Stars have pretty good heat transfer. Put some thermal compound under the stars and you'll be fine.
