High Intensity Discharge (HID) is a new type of lighting technology that's primarily different from the conventional halogen bulbs that use a heated tungsten filament. Unlike Halogen lamps, High-Intensity-Discharge (HID) lamps don't have a filament but create light by the arc between two electrodes. The arc activates the Xenon, which in turn ignites the metal halide. The light produced by an HID Xenon lighting system is greater than a standard halogen bulb and with less power consumption. HID Xenon lighting systems appear as a bright white beam which resembles natural daylight. The bright white beam offers greater visibility and is now being used on modern motor vehicles. These rugged new HID flashlights are capable of illuminating targets up to 3000 feet using xenon High Intensity Discharge (HID) technology. The extremely bright light produced by X1 flashlights, makes identification of your target and distinguishing colors in the dark much easier. The focused beam results in more lumens per watt on your target than other high power flashlights. The beam is be between 3-4' in diameter at 2000 feet allowing excellent peripheral vision of outlaying areas.
