I don't care if they are more efficient or more effective - whoever came up with the idea of bathing our night time streets in an eerie, unearthly orange glow really deserves to swing from one of those lamp posts.
I grew up in the sixties when the majority of lamp posts used conventional white lighting. Obviously I wasn't a driver back then, but I can honestly say that I never noticed a particular problem with those sort of lights - and yet some meddling idiot decided to remove the comforting glow of simulated daylight and replace it with a sulphurous shroud of yellowy orange. For God's sake - why?
It's ridiculous and I hate it.
