2 brands already mentioned, Zebraligt and Armytech, are highly recommended by me. I have a few models of both and had zero issues. I've even dropped them into the 9ft deep end of a pool for 5 minutes, and still running strong. Just clean dirt from the crevice between the cap and body before opening either.
The Armytech with the TIR optic seems to me to be a bit more for close up applications. Say within a room or around the camp site. The Zebralight seems to work better for seeing down the trail, or longer distances. Still works fine up close mind you.
Both brands have headlamp models in AA, CR123, and 18650 so take your pick. As for recharging, the new Armytech models have magnetic recharging, so no port/plug to open up or leak. Zebralight does not yet have that feature. With a charger and power bank or solar panel you can recharge easily.
Run times are long on both, and comparable for practical uses. I prefer the "Memory" one click on feature of the Armytech UI though.

That particular ZL was lost one night while off-roading. Fell off my head into about 3 feet of mud while getting my vehicle out of it. Found it the next day. Battery was dead, because I had it on high when I lost it, but after 13 hours in the mud, I just cleaned it off, and back in business after a recharge.
