Pulsar 805 Laser IR Flashlight is a high-power IR flashlight including a variable beam that can be smoothly adjusted from narrow beam to flood. Unfocused beam illuminates larger areas, the narrow beam light ensures the longest possible viewing distance. The design of Pulsar IR Flashlight allows spot position to be corrected in the field of view horizontally and vertically. To do this, loosen the ring fixing optical assembly, adjust the IR spot in the center of the field of the view (the NV unit should be on) and tighten the ring again. Featuring a weaver rail mountable to fit all Pulsar designs, the 805 IR Flashlight is equipped with focusable beam, adjustable collimation and smooth brightness control. Powered by 2AA batteries, it does not drain the internal power storage of a night vision device.
