As someone who drools over all the AAA-sized lights, I think the best economy value at the moment is this: BLF348 GB round 2 Bright with good tint, simple and well-made, beautiful, and 10440 can be used. I EDC a Tank007 E09, somewhat more expensive but with 3 modes also 10440 compatible. Fenix is better quality but IMHO not worth the extra cost. I haven’t tried these, but the Manker “Boney” is also well-liked as is the Olight I3s. For AAA only, the Hugsby XP-1 is also a good choice.
Not much else offers the value these lights do right now. You can get cheaper lights but they’re not good ones so why bother? Choose by the features you like and you will be happy with any of the above lights.
