Meanwhile, the “dark sky” movement criticizes LEDs as a major contributor to what it calls the “light pollution” that humans cast into the night sky.

As a former, quasi-astronomer, nothing at night is more impressive than a star lit sky. My first night in Colorado was unbelievable.

Really? I thought one of the major advantages to LED street lighting is that it is much more directional, so it leaks less light into the sky.

20+ years ago, sodium (?, same as below?) lamps were suggested but supposedly people didn't like how things looked (IIRC) in the light.

http://www.flagstaffdarkskies.org/for-wonks/lamp-spectrum-li... says low pressure sodium lamps significantly improve star viewing compared w/ LED due to the narrower spectrum.

Downvote science, bitches.
