Public lighting accounts for around 32% of municipalities’ electricity expenses. Severely affected by soaring energy costs, many municipalities have adopted the reflex of switching off outdoor lighting during part of the night. Modern lighting systems, using high energy-efficiency technologies, make it possible to achieve this primary goal of savings, while respecting strong values of climate change mitigation, biodiversity preservation, and citizen well-being.

It is therefore worth recalling the fundamentals of public space lighting:

▶ Safety: Adequate lighting in urban or rural areas helps provide a sense of security. It enables users to clearly perceive their environment, move around with confidence, and reduces the risk of accidents and antisocial behavior. This notion is all the more important as mobility habits are rapidly evolving, making certain users more vulnerable.

▶ Social & Economic Life: Public lighting supports social life by creating a welcoming and safe environment for public events such as festivals, night markets, and concerts.

▶ Compliance: Public lighting is governed by regulatory standards to which installations must comply. The decree of December 27, 2018, sets out the rules for preventing, reducing, and limiting light pollution.
