Full-cutoff luminaires, adaptive dimming, warm-spectrum LEDs, Dark Sky ordinances, and policy frameworks that reduce skyglow without sacrificing safety.
Darkness as a spatial planning resource — that was a theoretical concept for most of the 2000s. The Netherlands operationalised it: the donkerte-netwerk (darkness network) identifies priority dark corridors in…
LEDs reduce energy per lumen by 60 to 80%. Global installed lumens rose anyway. Kyba et al. (2017, Science Advances 3:e1701528) tracked Earth’s artificially lit outdoor surface between…
EN 13201 is Europe’s harmonised road-lighting standard — the document that defines what a compliant street lamp must deliver in terms of luminance, uniformity, and glare control. It…
France is the only EU member state whose national outdoor lighting law has produced documented, measured reductions in sky brightness. The Arrêté du 27 décembre 2018 relatif à…
Light pollution is solvable. The engineering exists, the policy has been tested, and the evidence is documented. France’s Arrêté of 27 December 2018 imposed legally enforceable curfews, a…
