The Night Eyes Infrared IR-350 Gun Light is very compact but yet capable of illuminating targets at well over 350 yards with the use of night vision equipment. It is extremely durable and is smaller, lighter and brighter than most other IR lights on the market. The light is 5.9 inches long, weighs only 5 ounces and uses an IR 850 nm LED. The IR-350 has two brightness settings with a maximum runtime of 6 hours depending on the brightness mode used. The IR-350 Illuminator requires no focusing or adjusting to align with the cross hairs. Whether your target is 20 feet or 350 plus yards just turn the light on and shoot. Another unique feature about this light is the included remote switch. The switch is silent when activated and has a dual-mode that can be used for momentary or on/off functions. You will NOT hear any clicking that can scare off your predators. This switch is super-high quality with a solid connection. Also included in the kit is a high density, rechargeable Li-ion battery and a 45 degree picatinny rail mount.
