With that design, wouldn’t the heat dissipation be quite poor or I am missing something??

Interested! THX

Looks to me that the whole heatsink, light engine and head is made of a single piece of aluminum I think it can have a good heat transfer.

What do you notice that makes you think that?

Small fins and not enough surface area for adequate heat dissipation, to allow the flashlight to sustain 2000lm for more than ~30sec…

It is a chunk of a flashlight, at 2000 lumen to warm up before you can not touch it may take more than 10 minutes, and with its surface area (even without a lot of fins) I estimate it can maintain the 2000 lumen without disasters. It will become too hot to the touch over time.

I am interested.

Sure, why not! Interested

2000 lumen with 26650 option would be a useful torch for me
