Luminetworx PoE high-bay fixtures and sensors have a huge advantage over traditional high voltage systems. First is the obvious removal of high-voltage cabling. Buy beyond that is the energy savings. We are able to power 18000 lumens at only 90 watts of power. Whereas a comparable high voltage unit will use 240 watts for the same output. We also need to consider the advancements in our installation tech allowing us to runf fewer cable and an de-centralized installation.
