Themes and Topics

The ALAN conference series is dedicated to examining all aspects of artificial light at night. The broad scope of the conference includes how light is produced (e.g. technologies, industry, and lighting design), where it is present (e.g. remote sensing); what effects it has on humans and the environment (e.g. ecology); how it is perceived by the public (e.g. perceptions of safety and security), and how the benefits and detriments of lighting may be balanced by regulation.
