I use some cheap chinese flashlight from tmart.com that uses a 18650 rechargeable battery. I also carry a personal fan that uses the same battery and recharges with a cellphone charger, so if needed I'll swap the batteries.
I used to use a Surefire and later a Streamlight but I got sick of replacing the expensive CR123A batteries.
I’ve got a Bostac BTZ-20 that is super bright. It’s rechargeable using a micro USB and I love it, except it’s a piece of junk. I have already replaced the battery once under warranty.

Hell of a lot cheaper than a surefire and just as good. (~$50 on Amazon)
Everyone focuses on Lumens, and it’s not where you should be looking. It’s the lens. Light can be bright AF but if it doesn’t focus, it won’t light up the tail of anything.
