Increase the capability of your night vision device with the LN-EIR LED Infrared Illuminator from Luna Optics. This compact, 850nm low-glow emitter won't be seen by game or human subjects, but will aid your NVD's ability to display and record images in the dark. Beam width can be adjusted from 3 to 6° and beam intensity is adjustable from 0.5 to 450mW. The illuminator attaches to your device by means of a 1/4" Tripod mount. The illuminator runs on one CR123A battery with a runtime of up to three hours.
