Lots of good info already posted in here, so i won't duplicate. The only thing i'll add, is I have been impressed with a buddy's Olight Baton 3 EDC light (not the pro version). I don't usually run Olights, but the Baton 3 is small, rechargeable, and puts out 1,200 lumens. It also clips on a hat if you need to go hands free. I don't love the button placement for the on-button, but it seems like a lot of light in a very small pocket-carryable package.
