the red one:
Clicky - Reylight Tool Cu 219
Twisty - Sofirn BLF CO1S SST 20 4000k
I love AAA lights and have more then i care to admit. Although i have tons of killer lights, the ones i use the most are the ones i can carry without too much inconvenience. However, i’m more comfortable carrying a 14500 Jetbeam Jet MK I with an AAA Astrolux Copper A01 as a backup. And i use them a lot almost everyday. How did i manage before that is puzzling me. When i wear a jacket i do have a D4 and an extra AAA or AA in there. Cannot have too many lights isn’t it? 
Still, one of the most impressive AAA/10440 light i do carry on occasions is the above mentioned Ultratac K18, Al, brass or SS version. A real bright little jewel. In the same vein i would mention the Lumintop Ant and Tool Ti with e-switch. Real classy lights.
Jetbeam µ is good too. Compact, lightweight and reliable twisty with useful modes, brightness and beam.
I’ve received a couple Sofirn C01S BLF this summer but gifted most of them. I have to get used to it but it is promising and quite cheap. No hurt in trying one.
PS: When you think about it, AAA lights are so small and lightweight that it’s rather straightforward to carry a few just in case. I believe i have half a dozen in my backpack… The rational is that they don’t ad much weight or space compared to carrying spare batteries in a box - and they act as protection for them, on top of being functional lights.
Yes, but its too heavy. ha ha. Actually, it could be nice, but wouldn’t work very well as a head lamp clipped to my visor. I don’t have the head band for it.
lumintop tool aaa Ti, i’m not fan of twisty head
+1 on the Thrunite Ti and it’s perfect firefly mode. Will stay on for 3 days and is a perfect baby light. Have been using it constantly in such a manner since January. Have also used it for several nighttime walks for several hours on Low 12 lumens and it has performed great.
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.
