I received number 0079. Fine light, and worth the money. I've spent more time fondling/playing with it than seriously it using so far. Of course, this is usually true for me, anyway, with new lights, pens, knives, etc. A guy thing? I think it fits better in the original green belt pouch than in the newer blue one (more secure due to better velcro overlap). I put in the two screws and left off the clip. Very nice white light. Easy to switch between primary and secondary. The three click dim setting is very dim - I had to look at it to be sure it was on. Full power is bright!
I've mastered the brightness menu enough to adjust the brightness, with the help of Peter's advanced instructions and the two nice simulators. Beautiful pieces of work - very helpful! I recommend a little playing with them. I found it helpful to have them "up" while making adjustments.
