In a Danish town, the lanterns are provided with red lights. It sounds like something out of a horror movie, but it makes sense

What would you think if you were driving through a few villages and one of them was bathed in a deep red light?

Anyone who has watched even a trailer for a horror film in recent years might be reminded of the lighting mood from one or the other scary film.

But we can give the all-clear: Should you ever travel through Denmark and you discover a blood-red illuminated village, this is only for the benefit of the local animals – especially the bats. But people should also benefit from it.

Red light for animal welfare

The Danish municipality of Gladsaxe has its street lamps on Red light switched (via afry.com). This decision is based on several studies stating that red light affects bats and others nocturnal animals less disturbed or negatively affected.

But not the entire city is bathed in red light at night. At certain points, especially at intersections used by cyclists, will continue the traditional warm white used.

Humans benefit too

For people, the light should be less glaring and disturbing. It also allows you to find your way at night without affecting your eyes’ ability to adapt to darkness.

That means: Eyes remain accustomed to the dark, even in well-lit areas, to see better in less bright areas.

This project is part of Gladsaxe Municipality’s implementation of the UN Sustainable Development Goals. It has set itself the goal of creating the best conditions for animals, people and biodiversity.

Of course we understand if you’re in the mood for real horror right now. We feel the same way! Have a look at our horror talk:
