What light ?
Umm, whut’s the question again?
That don’t measure AAA
The flashlight is just a distraction. Magicians do it all the time.
Before you know it there will be rabbits and white doves popping out of high hats.
The one that Dons young Niece is wearing there I think.
I take it you were to distracted to read:
Lumintop Tool CRI, Nichia 219c. Good mechanical clicky + compact, but not too compact size + smooth but shallow reflector + starting on Med = punches far above its weight. At home, I main it and only use the 18650s for fun and tint variety, or if I’m doing home repairs and need the extra runtime, which is not the downfall but the least good point of the Tool.
Hell, I like it so much I don’t dare take it to work anymore now that I know they’ve been discontinued. For that, I take my 4yo Thrunite Ti3 XP-G2, my absolute oldest light of good quality. The beam is a bit too floody for me, but the rosy neutral-warm tint is paydirt in the Cree lottery. Battery life is better than the Tool’s too, so no worries when I’m out and about, even less so since it plays second fiddle to my fatter primary.
My copper Lumintop tool AAA with 3000k sst20.
Only minor is that I sometimes have an accidental activation. Tool ti AAA is on the slow boat, hoping this one has less chance of accidental activation.

Is the Copper one a Massdrop with the E switch
I’d like to see something pop out of that pic. 
Thorfire Mini (TK01) is my most carried. Rides on my keys, the captive head is a big plus. Guess it’s 219c, but not 100% sure. Beutiful temp and tint for me though.
Have a Reylight Pineapple mini, also a really nice light, but the head unscrewed itself from the body a couple times in my pocket and I mostly stopped carrying it.
Several Thrunite Ti 2’s. Nice, good knurling, but cooler temp than I like and moonpight tends to break over time and had one total lemon, but they did replace it with no fuss.
Lumintop Tool copper. I think I bought the Nichia version, but my daughter claimed it right away and I never really used it.
BLF-348, a classic. Bought several, still have a 219b and a 219c.
Sofirn C01S. Just arrived today, looks like a contender. Disappointed that I was asleep at the wheel for the BLF LtoH UI. For me, starting on high with the option to go to low makes no sense vs. the reverse.
I guess if all you have is a hammer, everything starts looking like a nail;-) Had to chuckle at that remark. My Ti3 has provided very useful light for car maintenance along with many other things for years now.
Recently I started clipping it to a hat while walking the dogs and I think it just might be the most useful light I have right now. Normally I don’t wear hats but took it up after reading this thread. Approx 15 lumen on the brim doesn’t destroy my night vision yet I can see the doggie doo as well as untangle the leashes without effort or using a hand. Useful indeed!
Now that jacket season is upon us in the frozen north, I always have my C8 so I understand the sentiment behind the AAA not having enough light. Not everything is a nail though and sometimes these tiny lights truly are the most useful tool for the task at hand.
FWIW, the high mode of about 100 lumen is nearly the perfect amount of light or doing close work like car repairs and as I said the 15 lumen works fine for seeing what is right in front of my feet. 500 plus lumen is truly not useful for tasks like that. OTOH if you need to light larger areas then sure a AAA light may not be particularly useful. Everything is not a nail.

Olight i3s
Like Unheard, I like the little Olight I3E on my keychain or with a clip in my pocket 
But my heart belongs to the Lumintop Tool/Massdrop AAA flashlights as you can see on the pictures. They all have different LEDs because I am a HighCRI fan and so I always have the right LED at hand 
Furthermore all of them have a Preon Pocket Clip because this clip is much more stable than these friction clips and all of them run with Eneloop Pro batteries. 
For me. it would be the AngryFox Playfox K1. I think it’s the smallest multi mode single AAA light.
Sofirn C01 3200k
For strictly AAA, I have to go with Olight i3T EOS (love the clicky!) For the AAA form with a 10440 support, I’ll take the UltraTac K18.
The BLF 348. By far my most used 1×AAA light. High CRI, useful output, great value, looks good. If I’m awake, I have a BLF 348 on my trouser belt or my pyjama waistband.
