Nitecore just announced the "HC35":https://flashlight.nitecore.com/product/hc35 , their first 21700 headlamp. With a large cell and a quad setup, it looks a lot like the PL47. Notably the Nitecore has a more stable driver and more pocket friendly shape, while the PL57 has more LED options and higher output on a full cell. What does everyone think of this?
Update: I've finished my review of the HC35 if you'd like to read it. In summary it performs well and has great runtimes thanks to the giant battery.
Very interesting. I like that it’s a quad and constant current. If bezel can be removed could be a good host for led swaps. 21700 battery is a little too big/heavy for headlamp use. Single clip looks like it’s not quite secure enough.
