MINI MAGLITE® AAA LED Flashlight. The heir to the original Mini Maglite® 2AAA flashlight launched 25 years ago, this newest member of the family features the same classic look and size and the same simple operation – just twist the head to turn it on, turn it off and focus the beam. But thanks to a latest-generation LED light engine, it produces a beam whose intensity is nothing short of amazing – from a pocket-clippable flashlight that's not much bigger than a penlight. Specification Length: 127mm. Barrel Diameter: 12.70mm. Head Diameter: 19mm. Weight with batteries: 49.04g. Batteries Required: 2 x AAA Alkaline (included).
