I just picked up a Cree L1 yesterday, and I already own two ML-1 builds with different beam characteristics. I must say, I was less than impressed with the quality of the Cree L1 beam. There is a SIGNIFICANT dark ring that surrounds the hotspot, and many deformities that give the beam an overall 'rough and textured' look. Is this typical of the new Cree head, or do I have a dud? I only ask because I've read nothing but good stuff about it, and I didn't know if the issue was not a widespread one.
