The LED Upgrade 2 replaces the incandescent bulb of a AA Mini Maglite with the bright white beam of an LED, providing higher quality, more powerful illumination, and a few other bonuses as well. The long-life LED bulb virtually never needs replacing and is much more efficient - it increases your battery life by a factor of five!
Because the LED Upgrade 2 is fully focusable, you can adjust the beam from wide flood to narrow focus, according to the light you need for the task at hand.
Bright, economical, ecologically responsible, and functional - the LED Upgrade 2 is simply the best way to improve the quality and extend the lifetime of your AA flashlight.
