LED lighting could have major impact on wildlife

LED street lighting can be tailored to reduce its impacts on the environment, according to new research by the University of Exeter.

The UK-based study found predatory spiders and beetles were drawn to grassland patches lit by LED lighting at night, but the number of species affected was markedly reduced when the lights were dimmed by 50% and switched off between midnight and 4am.

LEDs made up just 9% of the global lighting market in 2011, but forecasts suggest they will account for 69% by 2020.

This has led to concerns about their effects on plants and animals, and the Exeter scientists say research is urgently needed to understand how best to prevent unforeseen ecological effects.
