Acuity Brands' Lithonia Lighting expands volumetric LED luminaire product line

Dec. 9, 2010
Date Announced: 09 Dec 2010 Acuity Brands, a market leader in innovative energy efficient lighting and control solutions, 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. The RTLED 2’x2’, 1’x4’ and 2’x4’ luminaires are available nationally through Acuity Brands’ Lithonia Lighting sales representatives and authorized distributors.
