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.

Olight i3T Eos
Still the Lumintop Tool/Drop.com AAA flashlights, in Post #69 you can see my complete AAA collection.
Here is my first Lumintop Tool Cu which I converted to E-switch 3 years ago (Lumintop Tool Copper with electronic switch) and which I still use regularly.
It was converted to a Nichia 219b with 3000k, has a Preon P1 clip which I adapted to the copper of the Lumintop Tool with heat coloring and this little flashlight works now for 3 years without problems, I can’t imagine a better AAA flashlight with such an ingenious switch and made of copper.
I never use alkaleaks. Ever.
My AAA sized 10400 light has been on a chain around my neck for almost 6 years now. With 5 levels and a max output of near 800 lumens, it’s Nichia 219 works splendidly.
This is my Photon Fanatic made Texas Poker of course.
Oh, April will be 7 years I’ve worn this little beaut…
The 18500 quad is my scratch built EDC, wear it on my belt or the hem of shorts. The custom folder has a 4” blade, obviously both lights are quite small. I, uh, seem to have a thing for Titanium. 
I can add Skywolfeye B16 to my Favourities list.
It has spent a few months on my neck and it will soon return to this duty.
It’s not a great light, electronics surely deserve some upgrade (and they will likely receive one). But the perfect floody beam shape with nice sizing really make it the best light I’ve carried on my neck so far.
I’m adding the Lumintop EDC01 to this list. It’s easily the tiniest and lightest minitorch I’ve ever owned, the fit and finish on it surpasses that of my Olights, the beam with the pebbled TIR is easy on the eyes, and it has one thing I wish the Tool had: mode memory. I don’t even mind that it’s High→Medium→Low.
Only have two complaints about it:
- (major) It doesn’t have a clip. For me, a guy that doesn’t like putting lights on keychains, this is a major issue, as one of the things I dig about this format is how I can clip it to my shirt and forget it’s there until I need light; as it is, I can only carry it if I have a pocket in my clothes. Normally I keep the EDC01 on a belt bag, but it’s inconvenient to have to unzip the pocket to fish for the torch inside.
- (minor) The only LED option is cool white; it’s a decent tint of cool white, not as good as the Tool AA, but still. A Nichia version (or just a regular Cree in neutral white with no outrageous tint shifts) would definitely be appreciated by us non-modders.
I’d have to say Manker E02 and E02H as well.
The direct access to an adjustable low, the completely adequate higher outputs, very good runtime and Nichia emitter are hard attributes to beat.
Reylight Copper Pineapple Mini with custom glow material
I would love them even more if they came in copper :D
ThruNite Ti (the original one, in Titanium) AAA-based. It is 162 lumens at max but starts out on firefly which is very nice. Has a Cree XP-L V4.
Great little light! Nice that it comes with a NW option but really easy to swap LEDs, too. I put a 3000k 80cri XPL in and its nice. Just wish the ti threads weren’t so scratchy.
