A few small lights I had around. The hs10 gets a lot of use as a night light and the ts10 is carried the most right now. Never really used the s21d in this form but it’s very compact!
Left-to-right:
Sofirn hs10 16340 2700k
Wurkkos ts10 14500 5700k
Sofirn sc21 16340 4000k
Acebeam Pokelit AA/14500 5000k
Sofirn sp10 pro AA/14500
Convoy s21d 18350 2700k (with Wurkkos 20350 tube and tail cap)
Everybody needs a TS10.
It may not be The Perfect Light, but it comes a lot closer than many other lights. Do you want great CRI and R9? The CPS2323 is solidly 9080. Do you want lumens? The TS10 has more than enough for any practical use. Do you want small? It's the size of a button-top 21700 cell; you could shove it inside most 21700 lights and screw down the tailcap securely.
IMO, the only thing that could make it more perfect is a 4500K 219b emitter swap.
You are remarkably consistent in your recommendations Jerv!
