Hello Arc7271 & welcome! :welcome:
This is exactly what I've been searching for as well. I have ordered a few 18650 flashlights but haven't yet received them, so I can't officially recommend them yet (since I haven't tried them myself in the woods).
I have received a Thrunite TN4A which is a great flashlight. It takes 4x AA batteries. You should read a few reviews (and posts) and watch a few YouTube videos of this light. Oh, and I found both a lantern and diffuser for it (I posted a thread about that) so it will serve us well inside our cabin as well as outside.
I'd like to buy a high lumen output flashlight (+3000 lumens) to check for bears etc, but I'm wondering if it would be overkill. Although, I've read that the output has to be 4x more to appear 2x as bright. So, 4000 lumens would only seem twice as bright as 1000 lumens? Maybe an experienced CPF member could answer that. I'm still new and learning.
I'll subscribe to this thread to see what other's suggest you buy. Thanks for posting this!
