The Dorcy 41-0901 International’s Zoom Focus flashlights is state of the art. Zoom Focus technology enables the user to adjust the beam/focus of the light from a tightly focused spot with maximum reach all the way out to an extremely wide area flood light with perfectly even edge to edge light distribution. All this is made possible by Dorcy’s Patented TIR optical technology. The Total Internal Reflectance optical system uses a patented acrylic lens that is so efficient almost 100% of the light produced is projected onto your target with incredible precision. This flashlight has 115 lumens.
