The Las Vegas Convention Center selected approximately 2,000 Holophane® DualBay high bay luminaires from Acuity Brands, Inc. (NYSE: AYI) to improve lighting and reduce costs in its 3.2 million-square-foot facility. Installed in the convention center’s central exhibit halls, DualBay high bay luminaires feature Holophane ISD Superglass™ reflectors, dual lamp technology, solid-state electronic ballasts, and a state-of-the-art thermal management system to deliver better light quality, distribution and energy savings. The luminaires are ideal for a variety of industrial, retail and commercial applications.
“DualBay high bay luminaires have reduced the convention center’s energy consumption by nearly 40 percent while creating a vivid, uniformly lit environment with less glare and strain on the eyes,” said Joe Toro, electrical supervisor for the Las Vegas Convention and Visitors Authority.
Using two, 315-watt ceramic metal halide lamps, the high-efficacy DualBay luminaire delivers a 90+ color rendering index (CRI) and up to 112 lumens per watt in the Las Vegas Convention Center. The light levels in the central exhibit halls now range from 60 to 85 footcandles, with greater intensity in areas with lower ceilings.
“Our exhibitors have commented about how well their products look on display,” said Walter Laub, senior manager of facilities engineering for the Las Vegas Convention and Visitors Authority. “The new lighting complements the exhibit space, making it more attractive and easier to promote overall.”
The fixtures are mounted up to 40 feet and positioned so light patterns overlap to help eliminate the possibilities of dark areas. An automated computer system controls the lighting and allows luminaires to be turned on or off individually.
