Wow. Over 24 hours later, there are 40 views and no responses. Are people shy or just confused?

I guess I'll go first, then.

Single 14500: Acebeam Rider RX SS
Single 18650: TBD - have my first two on the way.
Single 21700: Acebeam E70 SS (FC40 4500K version)
Single 26650: Don't own any yet, but I'm looking. The D4SV2 looks nice, and the Convoy M3-C does too.
Multiple-cell (any battery type): Sofirn SP36 (5000K version)

Please feel free to bust on my choices, and more importantly, share your own.

I don't believe I have quite the collection of flashlights that you guys have. But the ones I have are quite interesting since I use them for light painting of subjects at night (night photography)!!

Single 18650:
- RGB Critter 2.0 (this is designed for flow art/performance, but I have been using it for light painting of subjects and it's working quite well so far, and the quality of the light is fantastic. This has 39 different colors. Charges via USB

- Wurkkos FC11 LED flashlight (this is a relatively "normal" flashlight, produces a warm white LED light, has brightness ramping, is waterproof, and is only $30. And yes, this too is great for light painting of subjects at night!

Double 18650:
- ProtoMachines LED2 (this is designed for light painting subjects and is utterly fantastic. The quality of the light is superb, and it gives you full control over huge and saturation across the RGB spectrum.

Where the sun sets fast

14500: Lumintop Tool AA v2.0

It just punches so far above its weight that when I had it and wasn't expecting to need long runtimes, I pocketed it. Don't have it anymore but it was an awesome little light. Hope its new owner is putting it to good use too.

18650: Convoy S2+

LED, collimator, anodising color... set it up however you want, Bob's your uncle either way. Mechanical tail switch, too, in such a compact package that I sometimes forget I'm carrying it. The lowest 0.1%/0.3% (don't remember which) mode could stand to go a touch dimmer, but that's a personal picked nit.

21700: Convoy M21B

This thing is BEEFY. It's got the same head design as the Convoy M1, but the head/body size ratio is a lot more reasonable. The amount and depth of the head fins allows for good cooling without sacrificing portability, which is perfect for the FC40 emitter I run on it. The whole package is set just right to extract as much performance out of the 21700 cell as it can. And with the standard 12-group firmware, it feels familiar right out of the box. This is my favourite flashlight so far, and I'd tote it a lot more if my need for personal lighting wasn't so meager, especially now in the summer when we get the sunrise at 4AM. 😒

That said, a caveat emptor: with my setup, the beam has a very pronounced "fried egg" effect where the spill and corona are white but there's a faint donut hole in the middle that's considerably warmer in tint, almost yellowish. It's inevitable when you put a big LED in a small-ish reflector. Doesn't bother me in the slightest since it doesn't affect CRI to my eyes, but some people are anal about their beams. In this case, pick a smaller emitter like the Nichia 519A.

26650: N/A

Don't own any, so no personal experience. I wanted to, until 21700 came out with its better energy density and more compact size, and I went with it. I'm keeping a look out for how 26800 develops instead; if it becomes more than a wildcat battery, I'll go for it.
