Are Eco-Friendly Bulbs BAD for the Environment?


Blue light-emitting diodes (LEDs) have been receiving positive attention after its inventors were awarded the Nobel Prize in physics last week.

They use around 90 per cent less energy than incandescent bulbs and last for 100,000 hours compared with 1,000 hours for tungsten filament light bulbs.

But while they may be good for the environment, a new study claims that the discovery may a problem for insects, which are more strongly attracted to the LED spectrum of light.

The research, by New Zealand-based institute Scion, found traps placed near LEDs captured 48 per cent more insects than traps near sodium-vapour lights.
