Ah, the tiny-123. Yes, Larry was kind enough to let me test one for a week. I then posted some comments on my experience (somewhere here on the CPF). Basically, we will not be making it or anything similiar until technology improves. I am concerned that the package is so small it left out several features I feel are essential such as a tail switch, better optics, etc. Funny thing is, if it was smaller, those items could be sacrificed for the sake of convienence. But it is too big to fit on a keychain (even the Arc-AAA is too big in my opinion).
I wanted to make sure my viewpoint was not being affected by any "not invented here" syndrome so I looked at each feature as objectively as possible.
This sums it up: It is too big and too small to fit in an ideal niche.
Larry has demostrated some excellent work and I hope we see more from this angle. Collectors should check out the auction going on for one of these lights. You can own a rare piece of excellent engineering.
