I'm a big fan of the ThruNite brand. Made in China. They come with nylon holsters, and spare O-rings. You can purchase throwers or floods, in cool white or neutral warm. I love the TN36, which is 6500 lumen flood, but it isn't an EDC. Shaped like a coke can.
My EDC is Thrunite 2CV2 LED flashlight, Cree XM L2 U2, Neutral white, $40 at Amazon.
1x18650 battery, Turbo (1040 lum/90 min), High (650 lum/95 min), Medium (220 lum/5 hrs), Low (11 lum/72 hrs), Moonlight (0.1 lum/90 days), Max beam distance: 212 meters
You can buy a bundle deal with the battery and charger. Stick with the Thrunite batteries. Lot of shitty Li-ion batteries out there. Thrunite sells in Amazon, and prices are cheaper than Thrunite website.
CutleryLover has a lot of videos on TN flashlights on YouTube.
Good luck!
