Well guys,
I got the speciment today and... I have tasted Heaven's nectar and found it sweet!
Oh I wish I had a camera right now! I had my hopes up for a bright light and I was not disappointed; I think I lost an eye to it.
After you install the lens in the head, the light is ready to fire up; make sure you don't aim at your eyes, head or inflammable substances.
The low level is very much like an arc aaa but with a wider and whiter beam while the high level is pretty much like an arc 4 on level 1. I don't have one to compare anymore but I can tell you it's not dimmer!
I only have one cr2 cell arround so I didn't do a runtime test on that but the 123 has been running for more than 1 hour already.
With the cr2 body, it's simply the brightest thing for its size I've ever seen. Truly impressive; I got to get more cr2 cells.
I've been using the light in flood mode (without the optics) because I find the wide flood of light really usefull. Maybe because I still can't see with my left eye right now... but mainly because the polished head acts like a reflector.
All right, for those who are waiting for a killer light, you won't be disappointed.
