CMG- Black Infinity LED Task Light Flashlight

CMG- Black Infinity LED Task Light Flashlight This stubby little one-LED light from CMG is powered by a single AA cell, is built like a brick outhouse out of machined aluminium, and has a simple turn-the-end switch mechanism. There's a tiny step-up DC-to-DC converter built into the back of the lamp assembly that turns the less-than-1.5-volts from the single AA into the thick-end-of-four-volts that the LED needs.The Infinity's quite compact, but necessarily a bit chunky compared with Mag-Lite Solitaire-ish flashlights that use a single AAA cell. One AA alkaline gives you around twice the capacity of one AAA, though, and will tolerate high current delivery better as well. So, all things being equal, it's reasonable to expect two to three times as much battery life from a AA-powered light as a AAA-powered one.
