Well thats just silly. When I was younger and only carrier a photon II in green for YEARS and, somehow, I survived. For the past 10 years or maybe more I’ve only carrier 1xAAA lights and they work great. Many years carrying a trusty Fenix L0Dce, only recently have I found a couple lights which I’ve been happy enough with to replace it. The Lumintop Stainless Worm is a stellar little light but I abhor cold white. Currently carrying a Thrunite Ti AAA with the neutral XPL and I’m loving it. I wish the threads were a little better (tighter and smoother) and I could appreciate a M-L-H mode order but for $20 its an amazing EDC light that really can pack a punch.
Not to say I don’t use other lights, but 9/10 times its my AAA edc light which gets the job done.
If I really had to pick only one AAA light, though, I think it would go to the Lumintop Ti. Its a bit larger than the Thrunite, about the size of my old fenix. But it has a flawless 219B with perfect tint, well balanced modes and a nice e-switch with virtually no parasitic draw.
