How does light affect insects?

In a joint project with Studio DL, the City of Hannover, and Enercity, we study how artificial light impacts nocturnal insects. Using intelligent light control, we aim to develop environmentally friendly urban lighting solutions.

Camera setup in the Zauberwald

An AI-powered camera system automatically captures images every 10 seconds, without trapping or disturbing insects. It identifies species based on shape and size, providing a non-invasive monitoring method.

Three locations, two lighting systems

The study focuses on three sites around the Maschsee:

• Location A – existing luminaires with gas-discharge light sources (reference) 
• Locations D1 and D2 – new LED luminaires with adaptive dimming and color temperature control (1,700 K and 3,000 K) 

The locations were chosen based on their biological and lighting characteristics, but are located outside of direct visual lines. The “Enchanted Forest” area is particularly valuable: it combines minimal light pollution with high biodiversity.

Intelligent light control in action

Two adaptive lighting scenarios are tested over daily and seasonal cycles. Comparison with the existing lighting provides insights for configurations that minimize insect activity while remaining ecologically responsible. 

Studio DL thanks all partners for their collaboration and looks forward to further scientific evaluation and implementation of the findings.
