The SureFire Minimus Tactical Variable-Output LED Headlamp features a high-efficiency LED that provides brilliant white light, adjustable in output from zero to 100 lumens via the knurled no-slip right-hand control knob. It runs on a single 123A battery contained within the tilt-control knob and features a battery access cap with a short leash to prevent dropping or loss. The proprietary refractive optic produces a wide beam optimized for your natural field of view and included red, blue and green filters give you the option of low-signature light that also preserves dark-adapted vision.
Another valuable safety feature: a setting for a long-running SOS beacon. The fine-weave SF camo headband is strong yet comfortable and features a moisture-wicking Breathe-O-Prene forehead pad. Built from tough polymer and aerospace aluminum, hard-anodized in Desert Tan, the Minimus Tactical is lightweight, yet like its siblings the Minimus Vision, the Minimus AA and the original Minimus it's tough enough for the rigors of combat, caving and mountaineering and is submersible to 3 feet for up to 30 minutes.
