I believe the round cylindrical without the hex had a polycarbonate window. I remember calling surefire about it after the lens melted due to my light being left on.

mm... thanks for the reply guys.. think I have a generation 2 in that case.. Is the lens made of glass for that one??

and oh.. how does one get the bezel open for Gen 2 one?? is there a tool similar to the HDS bezel tool which makes it easier??
