Micro FlashLED operates on three standard, replaceable, AAA-cell-type alkaline batteries. Since LEDs are 80-90% more energy efficient than incandescent lamps, the unit operates 20 - 30 times longer than the comparable incandescent flashlight, providing up to 96 hours or four days of continuous illumination at a diminishing light output rate. It retains 50% of its light output after one hour of continuous use.
Micro FlashLED features a push-button switch in the back of the unit to operate the LED light. It measures 4.5 inches long and just over an inch wide, and without batteries weights only 3.5 oz, with 3 AAA batteries, 4.8 oz. It has a focusable lens with a narrow- and wide-beam lens design that allows continuous varying of the light beam width from, for example, a concentrated tiny book size at 10 feet from a wall to lighting the whole wall, floor to ceiling.
