The included bright white LED insert and reflector replaces your existing Maglite bulb and reflector assembly while the included tail cap switch adds "click on - click off" capability to your Maglite. The LED bulb lasts a virtual lifetime and uses less power, giving you five times the battery life. Brightness is a powerful 30 lumens and projects a focusable beam 40 meters!

Works with "AA" Maglite flashlights only!
