Lamp posts that give enough light, but do not disturb flying bats. These are an invention of the Eindhoven company Signify, formerly known as Philips Lighting.
The first innovative poles have now been planted in the southern Dutch village of Nieuwkoop. A neighbourhood there is part of a nature network with breeding grounds for rare animals.
The lanterns are energy efficient and give off a red light. That light does not disturb the bats because a different wavelength is used. Normal lighting affects the behaviour of bats at night.
The project has been rolled out in a neighbourhood with nearly 90 houses. Each lantern can be controlled remotely.
