The City of Arezzo reduced the total cost of ownership for the Crocina Tunnel by upgrading to Cree Edge™ luminaires.
The total cost of ownership for the Crocina Tunnel in Arezzo, Italy was too high due to the excessive cost of relamping in a tunnel application. The city searched for more economical options and evaluated a range of LED solutions. The results concluded that Cree Edge™ luminaires offered the cost-effective solutions the city needed for energy savings, performance and little-to-no maintenance.
Arezzo wasted little time to upgrade all existing 100-Watt high-pressure sodium lamps in the Crocina Tunnel with Cree Edge™ tunnel luminaires. City officials noticed an immediate and dramatic improvement in uniformity, color, and brightness.
The City of Arezzo was able to reduce energy usage by 61 percent by installing Cree Edge™ with an integrated two-level system. In addition to reducing energy consumption, the Cree® luminaires deliver incredible uniformity that provides better visual perception over high-pressure sodium fixtures. The increased uniformity dramatically increases vehicle safety and visibility. With a life rating in excess of 100,000 hours, Cree luminaires require virtually no maintenance — translating into big cost savings for the city.
