Hello. I positioned the spots on the edge of an exterior staircase. during installation, the internal batteries should be charged because the lighting was great. the next day, it turns out that this is much less true because the solar panels do not have time to properly recharge the batteries. lighting is low and runs out quickly. It is true that we are in the fall and the hours of sunshine are fewer than in summer. it is also true that I am close to Paris and not in the south. but the fact is that it's not great. :-(
