With hundreds of low-pressure sodium (LPS) luminaires throughout the city of Tucson requiring significant maintenance and consuming substantial energy to operate, city officials made the decision to replace the lighting fixtures with energy-efficient LED luminaires from Cooper Lighting. Choosing Cooper Lighting's Streetworks OVH LED Cobrahead luminaires, the city replaced approximately 600 fixtures to reduce costs as part of an American Recovery and Reinvestment Act (ARRA)–funded project.
Officials applied for and received approximately $425,000 for a total upgrade to LED lighting. Immediately after converting to LED luminaires, the city began to see the savings. Tucson has saved approximately $3,000 monthly in electricity costs and officials expect to see at least $30,000 in savings over the course of the year.
"Residents and decision makers alike can see the improvement in lighting in our streets," said Ernie Encinas, transportation superintendent for the city. "The advantages that LEDs offer are unquestionable, from better visibility to lowered maintenance requirements. Most importantly, the city is seeing significant savings in energy costs because the Cooper Lighting luminaires run with significantly more efficiency than our previous streetlights, and we did not sacrifice light quality to achieve those savings."
"We are pleased that the city of Tucson recognized the many advantages of our LED lighting products," said Mark Eubanks, president of Cooper Lighting. "Cooper Lighting is always striving to ensure that our customers meet their energy cost savings goals, and it is rewarding to know that Tucson is doing just that with the help of our Streetworks OVH LED Cobrahead luminaires."
