Why do you say that LEDs don't light up the night sky? Surely this depends on the design of the streetlight and whether it's adequately shielded from spilling light upwards? I'm seeing lots of white lights in my area but since the design of the housing hasn't changed some of this new blue/white light is spilling upwards and can't be filtered out since I assume it's broadband.
