The LEDLB-24E-IR LED Light Bar offers high infrared light output and extreme durability for demanding operating conditions. This IP68-rated unit is waterproof to 3 m and produces an infrared light beam 900' long by 100' wide that can only be seen through the use of night vision goggles. 850Nm versions have a very slight red glow around the LED emitters when viewed from a certain angle, while 940Nm versions are completely invisible to the naked eye. This unit can run on any voltage from 9 to 42 volts and provides a rugged solution that is designed for use in industrial security applications.
