The two bores, each on average, 1,394ft (425m) in length and 33ft (10m) wide, had previously been lit with a combination of 100W, 150W, and 400W high-pressure sodium luminaires. The new solution, provided by Schréder, uses the FV32 LED tunnel luminaire. Each 240 LED version of the luminaire consumes 266W, while the 120 LED version consumes 131W. Overall, the new FV32 LED lighting system results in a significant decrease in energy consumption and the number of luminaires, from 1,253 to approximately 789 outside of the tunnels.
This lighting scheme is part of larger project by the Nevada Department of Transportation (NDOT), in co-operation with the Federal Highway Administration, to improve Interstate 80 through the Carlin Tunnels area in northeastern Nevada. The approximately USD 31M project includes enhanced roadway drainage, new concrete near tunnel entrances and the new lighting solution
