Well there are two countries with little LP: North Korea and Cuba. I like rum and Afro-Cuban Jazz, and Im not a big fan of kimchee, so guess which one I want to move to....

Yakima has installed a few on a few street's. They are insanely bright, incredibly " cold" white/bluish color. The glare they throw off at night with wet streets is horrible.

If there needs to be a case study done on how "Moar Light
s" doesnt makea safer town, they need to do it on yakima.
All it seems to do is give the bad guys better lighting to steal/aim by.

As I have said earlier, nebula filters are totally useless against LED lights, which blanket the whole visible spectrum with NO gaps whatsoever. These lights are going to make light pollution much worse, especially once they are cheaper to produce than the older high pressure sodium and metal halide lights that are being replaced by LED lighting. The ones in my city are nearly full cutoff lights, but they are blindingly bright.
