The Valgarizia tunnel is located on the SS 4 Via Salaria, in the municipality of Acquasanta Terme (AP). The intervention concerned the entire length of the tunnel for both the reinforcement system and the permanent one.
In the tunnel, consisting of a single pipe structure with 2 lanes, timely replacement of the old luminaires installed with the latest generation LED floodlights was envisaged, capable of reducing consumption and increasing safety. 418 Petrarca Tunnel floodlights (228 reinforcement ones and 190 permanent ones) were installed with a total power of approximately 30 kW.
The reduction in consumption requested by ANAS was met by Arianna’s Petrarca Tunnel floodlights.
Both the illuminance and uniformity values are in line with what was declared in the lighting design, both far above the relevant standards. The energy saving is 70% measured.
