Why are LED streetlights labelled “eco-friendly” just because they use marginally less electricity than their predecessors (LED streetlights decimating moth numbers in England, 25 August)?

Reading your article about their impact on insects, bats and other wildlife, I would have thought “eco-destructive” would be more appropriate, particularly as they are not recyclable and the mining and processing of rare earth metals required for their manufacture is environmentally devastating.

They aren’t too friendly to humans either. Many people contact our charity, LightAware, to complain about how they make health problems, such as migraine, much worse.
