Several municipalities have tried for several years to turn off street lights for part of the night, in particular to save money. Sannois, in Val-d'Oise, committed in June 2022 to turning off public lighting from 1:15 to 4:45 a.m.
The first objective was to reduce the cost, explains the mayor (DVD), Bernard Jamet. With the switch to LED, we have reduced the bill by two thirds while all the streets are lit all night, he says.
