Many makers of 18650-based lights are coming out with new 21700-based versions. Why not, look at the increased run-times, the turbo lumens? How can you go wrong, gotta keep current.
But does everyone really want to carry around a 21700 light? It's bigger and heavier. Is it the best compromise in size vs. capabilities?
Some people carry an 18350 light, or a 14500 light, the 18650 is more than they want to haul around in their pocket, their toolbelt.
What makes me think about this is my Quark MKIII light with a 16650 cell. I have so many lights to pick when I grab one, and I see to like this size the most. Just a bit thinner, but it feels better, at least to me.
So who wants to have a 21700 everywhere, even their headlamps? Or all the way to a 14500?
