LED luminaires deliver more light to ground

January 28, 2013

Acuity Brands Inc. has introduced 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. The fixtures can replace 35- to 400-W metal halide fixtures and 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, the luminaires use 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.

The fixtures are designed for more than 20 years of service life with almost 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, says the company.

The fixtures share the same footprint as traditional Wallpack units and can hide unsightly wall stains left by the original lighting units. According to the company, they 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-in. NPT when using surface conduit.

Lighting system owners can improve energy savings more by pairing the luminaires with lighting control products, including Acuity Brands’ compatible ROAM® monitoring system. The fixtures are suitable for a range of environments, including perimeter lighting and security lighting for industrial and commercial buildings, schools, parking garages, underpasses, and tunnels.
