Looks like I'm going to settle on the NiteCore SRT3 as my primary world travel/carry/always in the bag light (thanks to LOTS of help from all y'all!:rock:in previous posts). I picked up a LumaPower LM21(AAA) as a lightweight spare/backup. But, that's another battery (with less power/time) that I have to be concerned with, so, I'd like to find a compact, lightweight, minimalist AA that can take all the AA versions, perhaps 3 or so modes, maybe tail stand? There seems to be a plethora of super compact, little single cell CR123 lights out there. I'm not seeing the much of the same wrt single AA. A lot of the SRT3 ilk of full performance lights and a good number of tiny minimalist AAA keychains, but I'm not seeing something similar for the AA spectrum. Thoughts? Suggestions?
