LED lamps to solve light pollution?

[Toiletduck (Mitchell)]

This would be pretty great! Courtesy of BBC:

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.

A step in the right direction. Now, if they could all pick a single wavelength for streetlights (perhaps as a national standard), we could filter that out.

Councils will have to display intelligence and forethought first. Ha ha ha ha!

Less light polution would be a major bonus, plus the power savings would be significant and there's no warmup time so streetlights could even be put on motion sense after say 10 at night.

Sounds like a great idea to reclaim the skies.

The only issue with LED is with places that snow/ice. The LEDs dont emit enough heat to melt it off, unlike incandescents.

Ain't going to happen, pollies ain't interested and to many vested interests in keeping the status quo
