18500 energy density

It seems like the High Discharge (10A continous / 20A max) 18350’s cells have gotten denser lately topping out at 1100-1200mah.

I’d like to see a similar bump for the 18500’s. Currently, all other specs being equal, they are at the same capacity as the 18350’s.

I do see 2000mah 18500’s but they aren’t high drain (below 4A).

I recently got a FW1A Pro and swapped out the 18650 battery tube for 18500 one and to me it looks fantastic.

No real market impetus for 18500s, so no real innovation to push the envelope.

I love the 18500 tube on the fw3a series.
I use the Panasonic 2000mah cells and they are more than fine for the type of light and its uses. Be honest, FET is for fun on the fw3a.
I would actually estimate it does far more than 4a. I’m running mostly high cri emitters in them, but I can’t tell the output difference with the FET,maybe the tinest.

This setup with say a 219b/c is my favourite edc home light. 15mm drop in length is worth dropping 1500mah much of the time. 2300mah drop to an 18350 is too much.
I would love to see more 18500 lights. 18350 cells just don’t last long enough to me.
