I’d get the Skilhunt H300 144AR 4500K. Runtimes look good. It looks easier to modify.
I like that emitter in the ArmyTek Wizard C2 Pro Nichia.
I have a H600Fc. It’s one of my favourite headlamps. It’s a bit lighter and more compact. The beam is very floody but the tint isn’t great. It’s ok. The silicone mount makes it difficult to get the headlamp in and out.
