(Hessian Nature Conservation Act)
Section § 4 - Protection of living beings from lighting:
This section emphasizes the need to avoid light emissions to support the undisturbed alternation of activity and rest phases for diurnal and nocturnal species, in addition to provisions in the Federal Nature Conservation Act.
Section § 35 aims to protect light-sensitive species by advocating the avoidance of unnecessary artificial light, especially outdoor lighting that exceeds required levels or lacks a clear purpose. The measures include exemptions for horticultural production, regulations for designing lighting systems on public streets, and prohibitions on sky spotlights and illuminated advertising during specific hours. Municipalities have the authority to enact statutes regulating the environmental effects of light, and efforts are encouraged for insect-friendly designs in outdoor and built-up areas, with penalties for non-compliance.
