Lithonia IBG LED High Bay

Lithonia IBG I-BEAM® LED High Bay Overview

The versatile IBG I-BEAM® LED high bay boasts a single base platform design with the ability to select performance, optics, and housing options. This configurability takes the IBG LED from basic applications to complex environments, including unconditioned spaces. The IBG platform allows you to specify and pay only for what you need for general or targeted illumination, code compliance, and maintenance savings. Advanced LED technology offers maintenance-free operation and incredible energy savings of up to 65% versus fluorescent.

IBG LED is an ideal one-for-one replacement of conventional HID and fluorescent high bay systems. Applications include warehousing, manufacturing, gymnasiums, and other large indoor spaces with mounting heights up to 60′.
