With their rugged design and attention to detail, Surefire flashlights promise exceptional durability, dependability, and performance. Whether you need a rugged tactical flashlight for military use or on your own personal, outdoor-ready gear, the Surefire Kroma MilSpec has your back. A dual-output LED flashlight with four color spectrum choices, the Kroma is a versatile tool that is adaptable for tactical, recreational, or general use situations. Weighing in at only 5.1 ounces, with a length of 5.7 inches and a 1.47-inch diameter bezel, the Surefire Kroma is compact and easily carried. It is powered by a virtually invincible power-regulated main LED, which maximizes both output and runtime. The Kroma MilSpec is a high intensity flashlight that features a focused two-stage white light with two specific beam types and lower powered colored LEDs in blue, red, yellow-green, and infrared or IR. The main beam LED of the Kroma has a general use setting and a tactical mode, either of which can be engaged by pressing the shroudless, momentary-on two-stage tailcap. When you twist the tailcap, you can enable the constant-on feature. The low setting for these LED lights is only 11 lumens, about that of a traditional 2D battery device. At 130 lumens, the tactical output setting is bright enough to impair adapted low-light or night vision, temporarily blinding or disorienting an attacker. The Surefire TIR or Total Internal Reflection lens produces a tight center beam of white light, with a dimmer outer band of light to support situational awareness. Surefire’s TIR optics allow for a smooth beam free from hotspots or shadows, allowing for better visibility when the situation demands it.The Surefire Kroma MilSpec's lower-powered, multi-spectrum LEDs can be engaged using the five-position selector ring, which lies just behind the head of the device. With its click-stop function, the selector ring can be used to lock in a setting without looking, perfect for low-light situations. Each colored or IR LED produces a short flood light that is adapted for a specific task. The red and blue LEDs can be used for hunting and signaling. Because the red LED preserves night vision and is invisible to most animals, it’s an excellent choice for navigating the outdoors without disturbing wildlife. The blue LED is well-suited for tracking and identifying dark fluids, like blood. The IR mode allows for invisible illumination for the benefit of infrared devices. This LED device also features a rugged, aerospace-grade aluminum body that is hard-anodized for MilSpec durability. It also includes a tempered Pyrex and anti-reflection coated lens. The Surefire Kroma is gasket-sealed with a weatherproof O-ring and runs on two 123A lithium batteries, making this flashlight tough enough for any situation or emergency. Each 123A battery offers a 10-year shelf life, and together provide for over an hour of runtime at maximum output. The Surefire Kroma includes a heavy-duty stainless steel clip, allowing easy carry with a wide variety of different gear and accessories. Thanks to its precise and rugged construction, the Kroma MilSpec is sure to survive the most demanding tasks and difficult weather conditions.
