This Wilson LED bulkhead features a microwave detection sensor, which is a newer and more advanced technology than that of a PIR sensor. This sensor ensures lights switch on or brighten as soon as there is even the smallest movement in the detection zone, allowing for instant illumination of an area, letting people move around safely. This 22w LED bulkhead gives out 1710 lumens of natural white (4000K) light at a beam angle of 120 degrees.
