The Institution of Lighting Professionals has announced the release of Guidance Note GN08 Bats and Artificial Lighting at Night, with updates on LED technology and control, and a mitigation hierarchy for applying lighting where bats could be or are present. Developed in conjunction with the Bat Conservation Trust, the updated Guidance Note features a series of case studies, and is intended to raise awareness of impacts of human-made light at night on bats, as well as strategies to avoid and reduce harm to bats.
