This 14w LED POLO bulkhead has both a microwave sensor & corridor sensor functions making it ideal for places that don't need constant lighting but require instant illumination when it is needed. The microwave sensor is more advanced than a typical PIR sensor and is able to pick up even smaller movements in the detection area. This LED bulkhead is energy-efficient, provides 1296 lumens of natural white light (4000K) and is great for use in the hospitality sector and in factories.
