The LED street lights have shown up in my neighborhood in CA over the last year. Frankly, now that I see them in place, I don't like them one bit, for the same reason that I don't like LED brake lights on vehicles (as if we need to conserve energy on brake lights, please!): each super-bright LED is a very intense point of light which immediately makes its mark on my retinas and I see the spots for quite a while. I can't be the only one with this problem, and I can't imagine it not having a long-term effect. Sodium, fluorescent, and other kinds of lights seem to more often be accompanied with some sort of diffusion that eliminates the high intensity pinpoints from direct view. Not the street lights: one glance at those and I get a lovely 8x20 matrix of dots in my field of view for the next several minutes (or a 1x40 string in the case of brake lights). I think some improvements need to be made before they continue rolling out en masse.
Tangentially related, I don't particularly feel like we need street lights on all night long. What if we just lit up side walks with low posts (perhaps lower even than the FOV of a typical driver - enough to light the path and cast enough ambient light for pedestrians to take advantage of, but WAY lower power than the street lights, and with no intent of lighting the entire community? If my car's headlights are sufficient in the back woods where there are no street lights to drive safely on the most treacherous of roads, then why would I need street lights to guide my way in town where the roads are all flat and predictable? I, for one, would welcome a far less lit night sky for star-gazing and total overall reduction in energy consumption.
