We had LED lights fitted around our neighbourhood a few years ago. I think the sky is not quite as bright, but if you happen to catch sight of one they can be quite dazzling. They’ve offered to fit a directional baffle for me if I feel any particular light is a problem. I’ve not yet taken them up on that (and goodness knows how long it would take before it was fitted!) but it is useful to know.
