Here is the urbis sapphire 2 in my collection. It runs a 150w CDO-TT lamp and it's believed to be from column TW088 on the A5 in hockliffe, Bedfordshire. It originally ran 150w SON but the original electronic ballast failed so it was replaced with a CDO-TT ballast

Here is the internals of the lantern
