Light should foster well-being. Yet too much light or incor­rect light becomes a strain on the envi­ron­ment, a waste of energy, and cre­ates light pol­lu­tion. As a man­u­fac­turer, Selux can con­tribute to reduc­ing light smog by means of dark sky-con­form­ing lumi­naires. Leg­is­la­tors are also becom­ing active in this area: in var­i­ous regions of Italy strict reg­u­la­tions on light­ing in public spaces have long been in place, while France is now acting with a law on the ​“pre­ven­tion, reduc­tion and lim­i­ta­tion of light pol­lu­tion”. A most wel­come step!
