The UK government has opened a public consultation on lighting sources and labelling, with a view to implementing the EU’s EcoDesign regulation into UK law. It’s an important opportunity to highlight the issues of light-sensitivity.
Artificially lit surface of Earth at night increasing in radiance and extent
Continued improvement in the luminous efficacy of light sources and increases in gross domestic product (GDP) have resulted in tremendous growth in artificial light use over several centuries. Historically, lighting has been subject to a strong rebound effect, in which increases in luminous efficacy result in correspondingly greater light use rather than energy savings.
