Just found out about these cool streetlights. I have no idea if there has already been a post for this since its not new news. Sure there will be little improvement in viewing during a new moon but every other night there will at least be a little less to a lot less light pollution. 
I honestly don't know what percent of light pollution street light make but less is better. This idea may not be the perfect street light but I'll take it over what I've got. Plus it can always be improved upon.
I'm sure some are going scream safety but these lights could always be programmed to shine more in "danger areas" to provide needed lighting.

I've never seen hard data on this -- which I'd love to do. Frankly, it seems like a critical question, and one that's relatively easy to determine from aerial photographs. But my guess, based on what I see flying into cities at night, is that streetlights are responsible for at least 50% of all light pollution. The other major offenders seem to be lit-up playing fields, car headlights, car dealerships, and large lighted parking lots. As far as I can tell, everything else combined is negligible compared to any one of those five sources.

Thanks. For some odd reason I had never tried to figure the main sources of light pollution out until I had stumbled upon Seed magazine showing a picture of these lunar-resonant streetlights. Then wondering how much they would help if all street lights became lunar-resonant streetlights. I guessed that street lights where a big factor but beyond that I had not put much thought into it other then the fact that I hate light pollution.

Seems to me it's all backwards, at least as far as light pollution is concerned. The plan is basically to dim the lights during the full moon and then turn them back up when you might actually see some stars...

Half true since there not adding any lighting during a new moon and taking it away when it won't make a difference.
This plan was set up by environmentalists not astronomers after all. The real question is how astronomers like us can add to plans like this to help our goals too...
After all they will want our support to make plans like this a reality. So if we can add to there plans by let’s saying adding shades to direct the light so even less light is needed and therefore even less power is needed, we both win.
It's true that they win more. The publics’ momentum is with them, not us, after all. (We probably will gain some support after people start to realize that crime levels haven't really changed and a lot more support once people can actually see stars.)
If a plan like this was to come to be, all we would need to do is build on it (easier said then done of course). Lets face it we win never win the battle against light pollution, if our objective is to get rid of it completely, because there win always be a need for lighting.
Needed lighting is of course debatable and we must stand for as little as practical or loss a lot of needed support. Once we reduce a large portion of it we will need to fight to keep it that way and make as many small improvements as possible.
Also when, if ever, we do see a large reduction in light pollution then we will have an easier time helping others to discover and enjoy astronomy (as long as we can get help them discover the right scopes too). Then with more people enjoying astronomy we will have a slightly easier time reducing the already lower levels of light pollution because we will have more people pushing on our side pushing for even lower levels of light pollution.

I've heard that with the proper outdoor lighting, that it would not be visible from satellites. Now, the entire coasts can be seen from the sky.So, it is possible to have the proper lighting, without destroying the night sky in the process.

Wouldn't it be wonderful if we reduced the light pollution by 50%. That is something to dream about.
