Pulsar X850 IR FLASHLIGH Nv Accessory LED Diode Equivalent IR Power mW: 30-350 - Diode type: LED - Lens diameter mm: 35 - IR Wavelenght nm: 850 - Power Supply: 3 (2xAA) - Range of beam divergence degree: 3-9.5 - Rifle Mount: Weaver / 1/4 socket - Average operation: 2 hrs - Operating Temp: -20 to +40 - Lens Material: glass - Body Material: plastic - Length: 152mm-165mm - Width: 45mm - Height: 52mm - Weight: 7.8 oz - Focusing: Pulsar's high-power IR flashlights include 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. - IR Spot Position: The design of Pulsar IR Flashlights allow 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. - Power: Power is adjusted by rotating the wheel on the body next to the ON button. Adjustment of both - power and spot divergence angle - helps achieve best illumination of an object in specific observation conditions. - Mounting: Pulsar IR Flashlights are equipped with a Weaver mount adaptable for a Weaver rail on most modern night vision riflescopes and optical units as well as hunting or sports and pneumatic weapons. The package also includes an adapter that allows flashlights to be attached to night vision units outfitted with a 1/4 inch tripod mount. - Indication: When the IR Flashlight is on the LED indicator located next to the battery container lights up. When the batteries are low the indicator changes a color the latter depending on the IR flashlight's model.
