I have been watching this thread for a few weeks with great interest, and finally wish to write some things down.
To my knowledge, I am the first CPFer to have expressed interest in a CR123 Key-chain light from TnC. I made my wish known in the B/S/T -> GB&P forum thread "TnC_Products AA Luxeon?" on 05 August 2004; check it out!

Those days, Arc was still flashing, and folks had other choices for CR123 lights, so no one else seemed to be interested. Good to see that now there is tremendous interest in a Lithium KeyLux.
TnC Keychain lights have a character of their own, which is so different from ArcLS/4, FFII, or LarryCR2. First of all, TnC KeyLuxes are not muscle lights. These are tiny lights that run for a life-saving length of time, with a useful (but not Blockbuster) brightness. Given that Chris would most likely stay away from thermal issues ("TnC = Takes no Chances"), it's quite possible to make a very good KeyLuxCR2. And maybe a PocketLuxCR123 too, in between the KeyLux & HyperLux series.
Having seen the bulged out heads in KeyLux-N & -AA, I wonder whether this was based on design need (reflector/converter/thermal), ergonomics (convenience of one-handed operation), or aesthetic choice. I'd personally prefer a cylindrical design.
In a light designed in the spirit of KL-N & KL-AA, I could even live with a single brightness level, if that would make the light more reliable. HA-Natural, of course. Lack of artifacts in the beam is more important to me than a slight uniform tint (OK, maybe as long as it's not purple or rotten-green).
Again, I'm hoping & praying that there'll be a KeyLuxCR2 & a PocketLuxCR123. Since I cannot afford both at this time,
I'll go for the KeyLuxCR2 first. Best news I have heard yet on the matter is: "I am going to try to keep the cost of the light around $80.00", to which my hat's off to Chris, for he should know that he can make whatever he wants, and still sell for double that price.
May everybody's dream come true in the New Year! /ubbthreads/images/graemlins/wink2.gif
