But its impact doesn\u2019t stop there. It also affects biodiversity, the quality of the night sky, and, of course, municipal budgets\u2014particularly through energy consumption. This is an issue that should not be underestimated.<\/p>\n<p>With GROUPE RAGNI, discover the four mistakes to avoid to ensure the success of your public lighting projects, whether they involve new installations or renovations.
