'LED street lights are disturbing my sleep'

In towns and cities across the world, the colour of night is changing. Traditional yellow sodium street lights are steadily being replaced by white LED bulbs. The new lights use less energy, dramatically cutting carbon emissions and saving money. But not everybody is happy.

Less lighting has no impact on crime or collisions

Reduced street lighting at night does not lead to an increase in crime or car crashes, a report suggests.
Researchers analysed 14 years of data from 62 councils in England and Wales which had tried strategies such as permanently switching off lights or dimming them. They said the findings could help save money and reduce carbon emissions.

Harbour light 'attracts ship-damaging creatures'

Artificial lighting in harbours is attracting sea creatures that damage ships and boats, a study suggests.
Scientists believe that the night-time illumination is altering the behaviour of some animals that attach to vessels' hulls. Keel worms, for example, are lured in by the lights.

LED streetlamp aims to improve public's view of stars

Researchers believe they have come up with a new type of LED-powered streetlamp that could radically reduce light pollution.
Current designs "leak" large amounts of light in unwanted directions, obscuring views of the stars, wasting energy and making it harder for drivers to see.
The team, based in Mexico and Japan, said they believed their solution was the "best ever reported".

Light pollution is costly, situation needs to be addressed

The recently-released NASA image of Europe taken from its space station and which shows Malta as a bright orange blob of light with more light concentration in the harbour and Freeport areas, has shocked us.
But what action is being taken?
In an interview with our sister paper The Malta Independent, which will be published tomorrow, Alexei Pace from the Malta Light Pollution Awareness Group gives simple recommendations to improve things.
