Folomov C2 Super-Mini EDC flashlight. 525 lumens, with USB rechargeable battery.
BUY the C2 from Amazon Prime;
https://amzn.to/3h6YeuS.
It's under 2" tall, and weighs less than 1 ounce, but at 500 lumens on turbo, is pretty bright!
It comes with its own 14300 USB rechargeable lithium battery, and has 5 regular lighting modes, plus 3 flashing modes for emergency signaling.
The written review on my website; https://lightsngear.com/folomov-c2-mi... features outdoor beam pics of the C2.
