The Big Ass High Bay LED is a high performance, high efficiency LED luminaire engineered to be the ideal fixture for industrial and commercial environments. Unlike competing fixtures that are made of stamped sheet metal, the Big Ass High Bay LED features a single piece housing of anodized, extruded aluminum, which provides superior heat dissipation and impact resistance. Our patent pending lumen maintenance tray not only protects the fixture from dirt and debris, it also provides optimal light distribution.
