For the best headlamp, I recommend the Armytek Wizard C2 Pro. It's bright, efficient, and durable. There is a Nichia version which has superior light quality, but has a lower max brightness then the non-Nichia (Cree) version. While it comes with a proprietary built in magnetic charger, it uses standard 18650 sized lithium ion cells, meaning you can either buy a separate external charger or a battery with a built in USB-C port.

On the budget side, there is the Wurkkos HD15. It's less efficient and durable, but far cheaper. It has 2 different LEDs. There are models that have a throw/flood LED combo, and ones that have a white/red combo. This headlamp does have USB-C port built in and uses the same 18650 batteries.

Convoy S6 KW CSLNM1.TG. You can buy the pocket clip separately and get an 18350 tube if you want. It has a deeper reflector than the S2+.

I did some more testing, and it seems you're right. Although, after factory resetting it still does the same thing. Looks like it's the default, and I don't see where to go to it in the UI.

The upcoming M44 will be using a buck or buck/boost.

Look at Amrytek lights.
