Transition from conventional to light‐emitting diode street lighting changes activity of urban bats
Summary Light pollution is rapidly increasing and can have deleterious effects on biodiversity, yet light types differ in their effect on wildlife. Among the light types used for street lamps, light‐emitting diodes (LEDs) are expected to become globally predominant within the next few years. In a la...

Summary Light pollution is rapidly increasing and can have deleterious effects on biodiversity, yet light types differ in their effect on wildlife. Among the light types used for street lamps, light‐emitting diodes (LEDs) are expected to become globally predominant within the next few years.
