Acuity Brands’ Lithonia Lighting Expands Volumetric LED Luminaire Product Line

Acuity Brands has again strengthened its portfolio of  LED ambient lighting fixtures with the introduction of the Lithonia  Lighting RTLED™ 2’x4’ and 1’x4’ luminaire models. The RTLED family  of volumetric recessed luminaires, which are factory-enabled with Acuity  Brands’ nLight™ intelligent controls interface, deliver high-quality  ambient white light for general illumination applications throughout an  entire space while reducing energy consumption, maintenance costs and a  building’s environmental footprint.
“The RTLED product family includes a powerful combination of advanced technology, energy-efficiency and high quality of light. These superior  LED lighting solutions represent an innovative breakthrough for use in  interior spaces, which many leading customers across North America have  already deployed, including educational applications at San Diego State  University and the University of Akron as well as franchise retailer  SuperValu,” said Dave Ranieri, Vice President and General Manager,  Lithonia Lighting Commercial Indoor Products. “Adding the RTLED 2’x4’  and 1’x4’ options to the 2’x2’ luminaire provides our customers with a  complete and diverse LED lighting solution set for any ceiling  configuration. The built-in interface to the Acuity Brands’ nLight  intelligent control system enables plug-and-play connectivity to  occupancy sensors, photocells, and manual wall controls. Network  connectivity to an nLight system provides a complete solution by  cost-effectively integrating time-based, sensor-based, and manual  lighting controls. This maximizes the luminaires’ energy-efficiency  while significantly reducing the ROI payback period,” added Ranieri.
Powered by an advanced LED light engine, the RTLED luminaire delivers a superior lighting environment: high color rendering (80+ CRI), 3500K  color temperature, and full range dimming through the nLight 0-10V DC embedded control device. The RTLED also reduces maintenance costs by  delivering up to 50,000 hours of light, reducing downtime and increasing overall productivity by not having to replace lamps or ballasts. With built-in nLight controls, the RTLED can be configured to perform  intelligent tasks—including dimming themselves by Lumen Maintenance, a  means of eliminating the waste associated with over-lighting early in  its life cycle. This maximizes luminaire life while minimizing energy  consumption.
Additionally, the RTLED luminaires feature a small, compact design (only  3-1/8” deep) and allow building owners to meet “green” and sustainability goals in numerous ways. The products contain no mercury  or lead and are made with recycled steel and other components and materials, which minimize waste in the manufacturing and distribution  process.
