It’s not a matter of if a headlamp or flashlight will crap out because you thought batteries were fine when they weren’t, but when. I was 2 miles up a steep rocky draw dry wash boardered with thick timber that was boulder hopping the whole way, and a headlamp crapped out. No big deal because of my backup batteries, but it was so dark a hand couldn’t be seen in front of the face and there was zero chance of safely feeling boulder to boulder. Never used backup batteries didn’t last 20 minutes. I would have had to spend the night if it weren’t for a backup headlamp. Over the years the number of “fresh” batteries that turned out to be dead makes that a much overlooked issue. Test voltage of anything you’re relying on. I can’t be the only one that’s also had top quality headlamps just stop working altogether and get tossed in the garbage. One had a weird parasitic draw when turned off and batteries would be toast in a month of just sitting.
As a practical matter I want a high powered headlamp for bushwhacking back to camp, and for any other use it’s annoying to use anything stronger than a reading light. Guys are tough packing 11 pound rifles around with 2 lb scopes, 4 pound tripods, a pound just for a harness to hold a 2-1/2 lb pair of 10x50s, timber hunting with spotting scopes in the pack, etc., so a few ounces for a second small headlamp that might keep you from spending the night somewhere uncomfortable seems reasonable.
