“Using photometric and spectroscopic sensors, we observed up to 50% night sky darkening during Earth Hour from 2011 to 2024 in Hong Kong, primarily as a result of a small but critical number of lights-out instances in central business districts, as evidenced by crowd-sourced photography records. The emission reductions mostly occurred in the 445–500, 500–540, and 615–650 nm spectral ranges---corresponding to peak emissions from LED billboard screens--- and in the 585–595 nm range, associated with metal halide floodlights used for facades and billboards. Our study identifies these sources as major contributors to urban light pollution.”

Contemporary shower fixtures are only one of the items that rankle the president. He has frequently denounced toilets that he claims require flushing “ten or 15 times” and LED lightbulbs, which he faults for making him look orange.

Die Initiative Paten der Nacht macht auf die Folgen von #Lichtverschmutzung aufmerksam und ruft dazu auf, #Gärten nachts dunkel zu lassen – für gesunde #Lebensräume und mehr #Artenvielfalt.
