GEC Z9531 Lantern Installations

The GEC Z9531 was the remote-geared, top-entry, 35W SOX version of the GEC Nightwatch. The canopy could only be made from aluminium, and the bowl either acrylic or polycarbonate. Once upon a time, they were fairly-popular throughout the UK, often being used on side-roads. They declined in popularity through the 1990s and early 2000s due to other 35W SOX lanterns competing with them, and more recently, concrete column replacement schemes. This decrease in popularity was not exclusive to the Z9531, as the whole Nightwatch range experienced the same downturn.

Column 1 of Ferrers Avenue sports a GEC Z9531.

The lantern appears to run 26W SOX-E, and is the later-type with a polycarbonate bowl.

An identical installation exists on Lancaster Drive, column E2:

This one is a bit grubbier than the previous example. Although it's not visible here, the lantern has a Zodion CdSi two-part detector drilled into the canopy.

I did tell a slight lie.... When I said there is an identical installation on this road, I actually meant there is two! Column E6:

The bracket has been taped up to stop the spalling concrete from falling!
