Versatility in LED flashlights is a key consideration for an Every Day Carry (EDC). A powerful flashlight that is compact, easily recharged, yet can also be powered by a regular AA alkaline battery makes it a versatile survival tool. The Olight S15R is just such an ideal candidate for a zombie apocalypse. Hey, if it’s good enough for a zombie apocalypse, its good enough for anything.
If you’re looking for a powerfully bright AA LED flashlight, no other comes close to the Zebralight SC5. This is unlike other hundred-plus-lumen AA flashlights that support 14500 lithium batteries, turbo-ing up to 220 – 300 lumens ONLY when their lithium-ion cousins are used. The SC5 can have a max output of 535 lumens for 3 minutes, before stepping down to 325 lumens… on a single nickel metal-hydride or alkaline battery! At the other end of the spectrum, the SC5 also comes with an ultra-low output of 0.1 lumens which can last continuously up to 4 months!
