City of Arezzo, Italy


Tunnel Lighting


  • 21 of THE EDGE® tunnel luminaires using three light bars, installed at a height of 16 feet, replaced (one-for-one) 100-Watt High Pressure Sodium (HPS) fixtures.


  • 61 percent energy reduction using THE EDGE with integrated two-level system that reduces power consumption while maintaining minimum light levels.
  • BetaLED fixtures deliver incredible uniformity (Uo=0.85 on the wall and Uo=0.45 on the roadway.) By providing better visual perception, (50 lux average on the wall and 2.4 cd/m2 average on the roadway) over HPS, THE EDGE dramatically increases vehicle safety and visibility.
  • In addition to a life rating of an excess of 100,000 hours, BetaLED fixtures require little to no maintenance translating to big cost savings for the city.

Energy Savings. Performance and Little-To-No Maintenance.

The total cost of ownership for the Crocina Tunnel in Arrezo, 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 THE EDGE offered the cost-effective solutions the city needed for energy savings, performance and little-to-no maintenance.

Arrezo wasted little time to retrofit all existing 100-Watt HPS lamps in the Crocina Tunnel with THE EDGE® tunnel luminaires. City officials noticed an immediate and dramatic improvement in uniformity, color, and brightness.
