@supernovae @pieist Exactly (regarding the point of turn off). Moreover, what’s happening is that, due to the higher efficiency, more light (LED) is being used than before. And for longer periods than before. So the savings in energy are not that big (if any). But my post was provocative: people don’t usually question claims from the industry regarding savings, and rarely confront municipalities with the real savings they could achieve by reducing light. They accept.
