The City of Fort de France has a public lighting network of about fifty years old which is the subject of an evolution linked to the development of the city. It has opted for more than a decade for a desire to master energy, a rational management of Public Lighting in its territory, which is also a source of significant savings. As a result, the City is part of a dynamic that must be pursued. In addition, in order to contribute to respect for the environment, the City of Fort de France aims to reduce its energy bill, in particular, its electricity consumption by upgrading its public lighting. It will be a question of replacing existing luminaires with more efficient and less energy-intensive installations, by installing components to optimise the operation of the lighting.
