Thanks ultra...
I just found out that the Ultrafire charger I got is multivoltage anyhow and uses figure8 leads which I have for most every country I would ever visit. So I'm slightly off the need for no-rechargables... but only slightly. I'm going to make note of what I've found and put it someplace online for others. It's been a real eye-opener how many different power sources one can get. :)
In the end... I've found that 1 9v Lithium battery WILL power a Lux III for a while with "good" brightness. I'd say about the same brightness as a stock FX or a little better to my wife's eyes. But that only lasts about 10 mins tops. This is via a CF core btw. I've tested this and this is now fact in my world. :)
As you might guess... since I've been looking for a LuxV or K2(min) solution... this is not going to work. Oh-well...
Thanks again for all your help everyone.

PS: Be warned... I still have ONE last question for this forum before I complete my first saber. ;D
