LED High Bay - Lithonia Lighting


Acuity Brands, Inc. has expanded its LED indoor ambient lighting portfolio with the launch of the PROTEON™ LED high bay from Lithonia Lighting®. The PROTEON luminaire can replace high intensity discharge (HID), fluorescent and induction high bay fixtures in manufacturing, warehousing, cold storage, commercial, retail and other large indoor spaces.   

The PROTEON LED high bay is for indoor spaces with mounting heights ranging from 15'-40' and ambient temperatures between -4°F (-20°C) and 131°F (55°C). Utilizing a robust aluminum extruded heat sink, the fixture provides superior thermal management to reduce operating temperatures.  Featuring focus, narrow, wide and spread distributions, the PROTEON LED luminaire meets both horizontal and vertical light level requirements as determined by the Illuminating Engineering Society (IES). The product comes standard with a semi-diffuse lens to reduce glare. For additional glare control, a highly-diffuse lens is available.   The PROTEON fixture features a custom light engine specifically designed for the lumen requirements of high bay lighting to achieve optimal performance and reliability. 

Using pluggable connectors, electrical components are securely mounted to a removable, maintenance-friendly tray.   Optional controls offer additional energy savings and can extend the life of the PROTEON LED high bay. The PROTEON fixture is available with Acuity Brands nLight® enabled controls that facilitate remote system configurability. Advanced features include the ability to group fixtures, adjust dim levels, schedule operation and monitor status.   “In addition to its reliability, efficiency and versatility, the PROTEON LED high bay has a lower total cost of ownership compared to conventional HID high bays,” said Ed Weaver, Vice President and General Manager Industrial and Emergency, Lithonia Lighting. “The PROTEON fixture uses less energy to operate and reduces the amount of maintenance required so customers can achieve payback in 2-4 years.”
