We’ve had them around my area for several years now, with my own road being one of the remaining few to still have sodium. I have to say that (to my eyes) my sky brightness has increased slightly since the LED lights were fitted, not decreased.
It’s Birmingham City Councils hope to convert around 750,000 streetlights to LED in the coming years. At one time I thought this would be a good thing, but now I’m not so sure. I live in hope that our Council is so strapped for cash (and it really is) that they will eventually turn them all off at midnight. However the voices of the “we’ll all be murdered in our beds” brigade have already starting shouting from their padded cells, so who knows what will happen!
Didn’t mean to sound so grumpy. Hope your sky is the better for it Steve!
