Simon Barker:
The mercury lamps were still in use in residential streets in Surrey, when I was younger. I remember them being a bluish white, when compared to ordinary incandescent lamps. Definitely not "warm white". The lamps were a bit bigger than domestic filament lamps, and enclosed in a faceted glass shade.
Perhaps more glare than low-pressure sodium, but not excessive.
Was that in the early 1980s?
A friend told me that back in the early 1980s when he was quite young he visited Surrey and one of the towns (it could have been Reigate) had mercury street lights that emitted a light that he found to have an unpleasant hue and hard on the eyes. He was used to the yellow low pressure sodium lights at the time.
