LPHB4 4ft Low Profile LED High Bay
Spec Sheet
All Product IES Files (zip)

The high lumen output luminaire is designed to be a replacement for HID and fluorescent high bays. It is optimal for lighting applications where long life, low maintenance, and consistent color rendering is required. Areas with limited accessibility due to fixture location or where heavy pedestrian or vehicle traffic makes maintenance difficult are ideal applications. The high wattage/lumen output allows the fixture to be used for warehouse, manufacturing and big box retail applications.
The LPHB Series body and housing assembly are ruggedly constructed from 22ga cold rolled steel sheet. Fixture is assembled with special thread forming sheet metal screws to prevent loosening from vibration. All hardware is zinc plated steel. Rigid stiffening brackets prevent twisting and bowing. Engineered for exceptional thermal performance using lightweight aluminum thermal LED heat sinks. Open structure design allows for natural convective cooling. Wireguard attachment points provided.
LPHB Series body and driver housing are powder coated with lighting white high reflectance (93%) polyester paint.
Optical System
High efficiency linear LED modules with acrylic diffusers provide a medium-wide light distribution with exceptional vertical and horizontal performance. Optics provide 93% transmittance of light.
