The Gerber Recon Flashlight has a long-awaited L.E.D format that lets you choose from four different colors of light, depending on your needs of the moment. The official name for this proprietary technology is D.I.A.L., which stands for Diode Illumination Adjustable Lens. Basically, this new design lets you dial in the color that'll serve you best: White for general situations, red for preserving night vision, blue for identifying fluids, and green for map reading. It's all powered by one AA battery so you can anticipate long battery life with the Recon. It weighs just 2.6 ounces yet it delivers a ton of task-specific light, right when you need it. Backed by Gerber's Lifetime Warranty.
