The City of Austin, Texas, is replacing 35,000 high pressure sodium street lighting fixtures with energy efficient Streetworks Navion LED Roadway Luminaires from Cooper Lighting.
The upgrade will help the city save more than $200,000 in energy costs, according to Cooper.
Austin’s recent Energy Efficient Street Light Evaluation process, which started earlier this year, was the driving force behind the city-wide update. Professionals evaluated luminaires from multiple lighting manufacturers over a three-month period. During that time, several factors, including fixture construction, efficacy, ease of installation and maintenance, and appearance were evaluated. As a result, Cooper Lighting’s Navion LED luminaires were selected for the project.
Cooper Lighting’s Navion LED luminaire features die-cast aluminum construction, long life and offers 30 to 70 percent energy savings when compared to typical luminaires, Cooper says. The luminaires combine superior optical performance with efficiencies as high as 95 percent and a choice of 10 optical packages to meet the requirements of many roadway applications. The product is available in two housing sizes with multiple lumen packages ranging from 3,600 to 22,000 lumens.
The luminaires feature tool-less entry and are designed to last up to 60,000 hours, or more than 16 years when on 10 hours daily use, while delivering uniform, warm, white light, Cooper says. Navion comes standard in a 4,000K correlated color temperature with an optional choice of 6,000K and 3,000K CCT.
Recent outdoor street lighting upgrades across the country include the illumination of a new interstate interchange in Idaho with LED luminaires, a project that also used Cooper products. The Chubbuck, Idaho, project uses Cooper’s Streetworks Ventus LED luminaires.
In January, Oregon utility Portland General Electric announced plans to begin switching 25,000 of its high-power sodium lights to more energy-efficient LEDs. Five counties and 47 cities are slated to get the lights in 2013 and 2014.
San Antonio, Texas, recently used Toshiba International’s TGT LED Luminaires to replace over 20,000 high-pressure sodium street lamps. The city’s pre-existing 250-watt HPS luminaires consume 310 system watts and are being replaced by Toshiba’s 100-watt 42-chip TGT LED luminaires.
