The Minimus^™ headlamp features a high-efficiency LED that provides a brilliant white light, adjustable in output from zero to 100 lumens via the knurled no-slip right-hand output control knob. The proprietary refractive optic produces a wide beam optimized for your natural field of view, and an included red filter gives you the option of low-signature light that also preserves dark-adapted vision. A valuable safety feature: a setting for a long-running SOS beacon. The Minimus runs on a single 123A battery contained within the tilt-control knob, and the battery access cap has a short leash to prevent dropping or loss. The fine-weave headband is strong but comfortable, and features a moisture-wicking Breathe-O-Prene™ forehead pad. Built from tough polymer and hard-anodized aerospace aluminum, the Minimus is lightweight, yet like its siblings the Minimus™ Vision, the Minimus™ Tactical, and the Minimus™ AA, it's tough enough for the rigors of combat, caving, and mountaineering, and is submersible to 3 feet for up to thirty minutes.
