The following photographs were taken on Saturday, 13th November 2010:

The two outgoing columns on this short road ended their days with GEC Z9464 90W SOX lanterns fitted. However, I believe that alternative lanterns (possibly Thorn Alpha 1s) were fitted when new. The columns are probably made to an imperial height, as they are definitely taller than an 8m column (and a 25ft column, for that matter), so are probably 30ft in height - about 9m in "modern money".

The lanterns are fitted with their own photocells, meaning that the original column-mounted cells have lain disused since the Z9464s were fitted. In the case of this installation, the older photocell appears to be a 1970s' Fisher Karpark SS9 part-night device.
