The ULTIMATE 2″ IR Light Cubes use 2 rows of 940nm infrared LEDs with flood reflectors to throw a beam pattern specifically designed for short range navigation illumination. The beam disperses 940nm light to the left and right for optimal visibility in complete darkness. After rigorous field testing of many IR LED options we chose the same 940nm infrared LEDs used on military and law enforcement vehicles around the globe and put them in an ultra rugged and waterproof aluminum housing. Unlike 850nm wavelength LEDs used in many other IR lights bars, 940nm LEDs produce virtually no visible signature past 50 yards. 940nm IR LEDs also outperform white light LEDs with 940nm cut filters in output and power consumption. This makes 940nm the absolute best option for covert driving lights.
