This long-awaited L.E.D format 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 you can anticipate long battery life which come with the Recon. It weighs just 2.6 ounces. Yet it delivers a military ton of task-specific light, right when you need it.
