Switching to LED street lighting could alter urban bat behaviour

The effect on bats of the replacement of mercury lamps with light-emitting diodes (LEDs) in street lighting has been investigated in a recent study. Artificial light affects bat species differently and the activity of species normally more sensitive to light were affected less by the new LED street lamps than by traditional mercury lamps. Use of LEDs may, therefore, help to reduce the impacts of outdoor lighting on light-sensitive bats, if used at an appropriate level.
