Cooper Lighting Ventus LED Fixtures Provide First High-mast Roadway Illumination for Chubbuck, Idaho Project

LED fixtures provide the required high lumen output and distribution for the 80-foot installation

PEACHTREE CITY, Ga.–(BUSINESS WIRE)– Faced with the task of satisfying both an interstate interchange project requirement to use high-mast lighting and the need to match the color temperature of existing LED fixtures on surrounding roadways, Cooper Lighting, a leader at the forefront of transforming the lighting industry and setting an unmatched standard for innovation and reliability, worked with state officials to find the best solution. With ample illumination, the desired color temperature and providing added energy efficiency savings, the Streetworks Ventus LED luminaire stood out as one of the only acceptable LED solutions to satisfy the Chubbuck, Idaho, project needs.

The goal of the project was to light a new interstate interchange with LED fixtures and utilize high-mast poles to minimize the number of poles needed in the design. State officials were already familiar with benefits of LED lighting, having used LEDs on previous interchange projects around the state, but using LED fixtures in combination with high-mast poles was uncharted territory.

In addition to being only one of three manufacturers with LED fixtures approved for use on the state highways in Idaho, Cooper Lighting was also the only solutions provider that offered fixtures with sufficient lumen output to be considered per computer lighting simulations. Since this application represented a first in the use of LED fixtures in high-mast lighting, state officials needed to ensure that the product would provide proper illumination compared to the traditional high-pressure sodium (HPS) alternatives, and so a field test site was created at a nearby rest area. This site allowed for an easy comparison of the light output and distribution between 100-foot high-mast poles with 400-watt HPS fixtures and those with the 285-watt Ventus LED fixtures.

“There are three major benefits realized as a result of this test,” says Ethan Griffiths, the principal technician in traffic services for the Idaho Transportation Department. “This includes the reduced power usage while still maintaining similar light levels, a much higher color rendering index (CRI) and longer time frames between required maintenance.”

In this case, the four LED …read more
