Las Vegas Convention Center Cuts Energy Consumption by 40% with High Bay Luminaires from Acuity Brands

April 1, 2013

DualBayhighbayluminaireApplication2LRThe Las Vegas Convention Center selected approximately 2,000 Holophane® DualBay high bay luminaires from Acuity Brands 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.

Based on the current success, the Las Vegas Convention and Visitors Authority plans to add an estimated 1,400 fixtures in two additional halls. For more information about Holophane DualBay high bay luminaires, please visit www.holophane.com or www.acuitybrands.com.


New Wallpack LED Luminaires From Holophane Cut Energy Costs Up to 77 Percent

January 9, 2013

LR-Wallpack-LED-HolophaneFixtures replace metal halide or HPS systems, offers 20+ year service life

Acuity Brands introduces Wallpack® LED luminaires from Holophane that deliver up to 6,500 lumens while reducing energy consumption by as much as 77 percent compared to traditional lighting units. Ideal for replacing 35 watt to 400-watt metal halide fixtures, Wallpack LED luminaires are designed with the same classic appearance that made the Wallpack line popular. Wallpack LED fixtures are offered in two styles with die-cast aluminum housing: W4G with prismatic glass lens and W4P with a polycarbonate lens for lower mounting heights requiring vandal resistance.

Available with 10, 20 or 30 LEDs, Wallpack LED luminaires employ individual optics over each LED to deliver a higher percentage of light to the ground where it is needed. A high-efficiency electronic driver delivers constant current to the LEDs and offers internal surge protection.

Wallpack LED fixtures are designed for more than 20 years of service life with virtually no maintenance. They can eliminate as many as 10 metal halide lamp replacements. Tests confirm the luminaires deliver more than 70 percent of their initial lumen output even after 100,000 hours of operation.

“Long, reliable operation ensures building exteriors or underpasses remain safely illuminated to boost safety and security,” said David Deck, Holophane Product Manager, Infrastructure. “Wallpack LED fixtures create comfortable, uniformly illuminated environments free of dark spots generally resulting from failed HID lamps.”

Designed in a traditional day-form, the new luminaires ensure an aesthetically appealing look that provides a seamless gradual upgrade to an LED system without interfering with an area’s visual appearance. The fixtures share the same footprint as traditional Wallpack units and can hide unsightly wall stains left by the original lighting units.

Wallpack LED luminaires are easy to install and require only three bolts to secure the fixtures to the mounting surface. Fixtures may be wired in recessed junction boxes through the back casting or through the top ¾-inch NPT when using surface conduit.

Lighting system owners can further improve energy savings by pairing W4G Wallpack LED luminaires with lighting control solutions, including Acuity Brands’ compatible ROAM® monitoring system. Wallpack LED fixtures are appropriate for a range of environments including perimeter lighting and security lighting for industrial and commercial buildings, schools, parking garages, underpasses, and tunnels.

Holophane Adds LED Technology To Industry-Leading Portfolio Of High Mast Lighting Solutions

August 1, 2012

New HMAO™ LED luminaire features multiple lumen packages to maximize energy savings and deliver up to 100,000 hours of maintenance-free operation.

Providing innovative high mast lighting solutions for more than five decades, Holophane has expanded its High Mast Advanced Optix™ (HMAO) lighting systems to include LED technology. Engineered with a state-of-the-art prismatic borosilicate glass advanced optics, the HMAO™ LED luminaire is ideal for large area and roadway applications including airports, rail yards, sea terminals, industrial facilities, DOT interchanges and correctional facilities.

The HMAO LED luminaire features prismatic glass optics that provides overlapping distribution from each LED module to ensure excellent uniformity of light and eliminates potential dark spots. The uniformity of the vertical and horizontal lighting reduces glare.

Also, by minimizing the direct view of the source LED with prismatic glass optics, the HMAO LED luminaires help improve visual comfort. The 180-degree rotating optical assembly can be aligned “street side” with roadways for asymmetric light distribution.

“The HMAO LED luminaire provides a long life rating of 25 years, reducing maintenance costs by 50% and reducing energy costs and C02 emissions by up to 74% over HID lighting systems,” said David Deck, Product and Market Manager, Infrastructure, Acuity Brands Lighting.

The HMAO LED luminaire is available in multiple lumen packages to provide customers options for light levels and energy savings. Available for new construction or retrofitting, HMAO LED luminaires make it easy to replace existing HID luminaires without rewiring or changing existing luminaire mounting arms.

In addition, the HMAO LED luminaire is 3G rated for high vibration applications. Adjustable twist-off photocontrols come standard, and the luminaire is compatible with the ROAM® wireless monitoring system from Acuity Brands.

Historic City Hall Get Holophane LED Relighting Facelift

August 10, 2011

Fans of the landmark City Hall in the City of Fountain, Colorado, have a more modern – and energy-efficient – lighting treatment to gaze upon, thanks to a relighting project using Holophane® Utility Full Cutoff LED luminaires. And, while the fixtures themselves are high-tech, their vintage styles maintain a nostalgic look for the City Hall’s tree and lawn-lined sidewalks and streets.

The goals for the LED-relighting project were improved nighttime appearance of City Hall, as well as reduced energy consumption, maintenance, and night-lighting pollution. The latter was achieved in compliance with guidelines from the International Dark-Sky Association through the fixtures’ full-cutoff features.

According to City Manager Scott Trainor, the new lighting provides a 30% savings over the 100-watt high pressure sodium lighting system that was replaced.
