This tiny, take-anywhere LED flashlight uses just one AA battery, but manages to emit a surprisingly bright 130 lumens with a 288-foot range and a 22-hour battery life. For a light that’s only 3.5 inches long, that’s a whole lot of power. The three levels of brightness allow you to adjust the light to your liking – just tap the tail switch. And no need to worry about changing the bulb anytime soon; the Fenix E12’s Cree XP-E2 LED has a lifespan of 50,000 hours. Bring it on your next camping trip or evening sojourn and you won’t be left in the dark.
