David,
It is good to see somebody from Thrunite reads this forum! I own an Archer 1A and 2A, which I love. They are two of the most solid lights I own and they did not cost a lot of $$$! I also have two Neutron 1A's, but they are not so solid! They are flakey when run on a single AA. In single AA mode, neither one will go into turbo mode. They both do OK if used with 2 AA's or a 14500. One of mine is being used as a 3AA light and it seems to like that configuration! My latest is the T4NA, and I am a fan of that light. I got the cool white, although it does not seem to be so. I also have a question regarding the light. I bought it a few months back, and there is no place for a lanyard, and you cannot use real high capacity NIMH AA's i it without them getting stuck. You just made an improvement in the light where you now can put a lanyard on it, and you either changed the battery holder or the bottom casing to fix the AA issue. Are these parts available separately? Thanks for your interest!
