Hi! :-)
There is in this flashlight O-ring between the glass and bezel?
Or glass just pressed by reflector to bezel (without O-ring)?
I asked because there are as minimum two versions of this flashlight.
One with O-ring and one without.
Also, how much this flashlight have cooling ribs(fins) on head? 7 or 8? On foto looks like 7. But really how much?

P.S.: Sorry for my bad english, but i hope you understand me.
