The lights in the tunnels under the Rocher will be changed to LED lights, with much of the work taking place this July and August. Work will start on Monday, July 10.

Currently, the seven tunnels under the Rock are equipped with 637 lighting fixtures, which accommodate 1,340 fluorescent tube-type lamps and high pressure sodium lamps.

The benefits of replacing these energy-intensive lamps with LED lights are multiple, the Government said.

The number of light fittings will be reduced to 213 and the total power will be divided by eight compared to the existing devices.

Renewal of the components every 10 years will suffice, their service life being between 80,000 and 100,000 hours.

The amount of time needed to close the tunnels for maintenance will be divided by four and the cost of maintenance divided by eight.

The first phase of replacement will be carried out over the months of July and August, exclusively at night, from Monday to Saturday between 21:00 and 05:30, which will involve the closure of the “Fontvieille”, “Noghès” and “Antoine 1er” tunnels.
