One thing I want to point out is that white light has worse effect on light pollution than warmer light, at least as far as astronomy goes. If you ever go to a stargazing party you'll notice everyone uses red flashlights if they need to see anything in the dark because it doesn't drown out the starlight.
That's because the warmer the light, the less it is affected by Rayleigh scattering. In other words, shorter wavelength (i.e., bluer) light scatters more. This is the same reason that the sky is blue.
Animals are also more sensitive/more attracted to bluer light. These harsh white LED street lamps are a death sentence for moth species.
