A:The Nitecore casts an incredible 550 lumens (just shy of a car headlight) in a mere 2.6 ounce aluminum alloy package. It’s both one of the brightest and smallest lights around. We also like that that it can be dunked in 6 feet of water, and that its lithium battery can be replaced with a common AA in a pinch. When you’re ready to recharge, use the Micro USB port on the side, just like on many cell phones and GPS units.
