Klarus G15 Flashlight
This waterproof aluminum flashlight from Klarus is small but mighty. It measures just 4.75″ long and weighs just 5oz. with the battery, but can crank out an impressive 4000 lumens in its 5-second turbo mode. Runtimes range from 200 hours in its lowest “moonlight” setting down to 1.5 hours at 2000 lumens.
