I’ve found that 16340 batteries don’t always work very well in my CR123A lights but still, I sure like them and in all these years 1xCR123A types have been the flashlight I’ve carried the most, even in Argentina where they are even harder to come across an more expensive. So sure, I guess that makes a strong case for them. Also, my night table light for when things go bump in the night is a +1000 lumen 18650, again, a powerful flashlight that fits such role very well.
I’ve been moving away from li-ion batteries this year. The technology is there now for AA lights. With the exception of very high lumen output, there’s really no need for the CR123/18650 lights anymore. And, the very high lumen lights are rarely needed.
No love for Lithium Ions? Yes, the 4x AA lights are getting pretty impressive, but I still prefer a single 18650; comparable runtime/output in a smaller lighter package for both the battery and the light, and a single spare 18650 is less annoying than 4xAA IMO…
BUT, and here’s where I have to be honest with myself and my readers, I still make sure I have a 1xAAA with me at all times. In a worst case scenario where my house keychain is all I have to work with, I’ll have an Olight i3S 1xAAA light.
The way I see it no matter what you do you should always have at least one AA or AAA light, and if you’ll carry just one, make that one a AA or AAA. If you have a second light make it whatever you want, expand into a powerful, potentially tactical-use light, but first cover the basics. Why a keychain AAA instead of say, a keychain CR123A which would work on standardizing my battery use? Because I know that in a worst case scenario I’m far more likely to come across AA and AAA. If after a large scale disaster I have to get by with whatever I have in my pockets, I know that in some hotel TV remote control, some old toy, somewhere I’ll find at least one old AA or AAA with some juice still left in it. If I can find fresh batteries, then its not hard to get well over 100 lumens out of a single AA EDC flashlight.
