Watchmaker:
Very interesting. Flashlights are like pocket knives for me...never seem to find the exact one I'm looking for, so I have a bunch that were "close but not quite".

Have you done any testing of the Xenon CR123 lights that Cabela's sells (called "XPG" I think, and they're sold in 6, 9, and 12-volt configurations)? I'm curious how the less-expensive brands compare to the top-dollar ones.
