Peerless—a leading designer and manufacturer of architectural luminaires and one of the innovative lighting companies under the Acuity Brands, Inc. umbrella—announces the release of Round 4, a comprehensive suite of LED luminaires in both suspended and wall-mounted models.

Round 4 luminaires have been designed with several carefully considered design elements including continuous glowing lenses that extend across the length of the housings, unique "L" pattern connectors that provide seamless corner illumination when two or more luminaires are joined together and sculptural end caps constructed from die-cast aluminum.

To save energy, Round 4 luminaires feature a 0 to 10V eldoLED® driver that is fully dimmable to black and the option to include an embedded sensor for daylight dimming and occupancy detection control.

To boost efficiency further, Round 4 luminaires can also be specified with nLight® digital controls to provide network controls connectivity, energy-saving digital lumen management or both. In the suspended models, an optional built-in nLight module allows for easy Cat-5 “plug-and-play” connectivity with nLight control and sensor systems. For wall models, a standalone nLight module can be ordered from Sensor Switch® to install above ceilings. The digital lumen management option provides constant lumen output, extends LED longevity and saves roughly 10 percent in energy use over the lifetime of the luminaire.

Designed to direct and diffuse light following the proprietary Softshine® engineering standards from Peerless, Round 4 luminaires exemplify the Peerless mantra of Lighting for People® by emitting soft, uniform and glare-free illumination. Moreover, many of the available optical packages meet the guidelines set forth in the Illuminating Engineering Society’s (IES) Recommend Practice for Office Lighting (RP-1).

"The Peerless Softshine process scientifically shapes the light output from our luminaires to provide best-in-class distribution and performance,” says Peerless Value Stream Manager and lead product developer Kai Jaffe. “In the case of the Round 4 LED luminaires, carefully designed injection-molded optics produce indirect illumination that is flat and broad across the ceiling in batwing distributions with no hot spots and direct illumination that cuts off high-angle glare."

Round 4 luminaires are available with three LED color temperature options and with direct, indirect and a several indirect/direct distributions. The suite also offers several models with specialized optics. It also deliver an expected 50,000 hours (12 to 15 years) of illumination to L80. They are also IES LM-79 tested, CSA/CUS listed, FCC certified and feature a Lighting Facts® label issued by the U.S. Department of Energy.

Round 4 Stairway wall-mount luminaires are embedded with an occupancy detection sensor pre-programmed to remain at either 10 percent or 50 percent illumination when stairways are unoccupied and brighten to 100 percent illumination when occupancy is detected. Round 4 Aisle/Stack suspended luminaires uniformly illuminate vertical surfaces, such as library stacks and grocery shelves, on both sides of an aisle. Round 4 Wall-Wash luminaires illuminate a single vertical plane from a suspended form.
