112EC. Shootacre Lane, Horsenden, Princes Risborough, Buckinghamshire With thanks to Tim Luckett for discovering this Survivor. Attached to a wooden pole that is to be found slightly north of Upper Icknield Way is a disused GEC Z5227 'Facetted Reflector Lantern', for 60 - 200 Watt GLS (incandescent tungsten filament), 80 - 125 Watt MBF (mercury vapour) or 45 Watt SO/H (low pressure sodium) lamps, and dating from the late 1940s - early 1950s. Google Street View imagery shows that this lantern has been out of use since March 2010 (at least), although as it is supplied in modern concentric cable, which terminates into a moulded plastic AC Ford enclosure, it must have still been in use in (approximately) the 1990s, with these items replacing the original cabling and fuse box.
The installation is positioned almost centrally outside a small group of houses. No other poles in the vicinity are equipped with street lighting equipment.
The lantern is attached to a curved top-entry bracket. Side-entry versions were produced too, with the bracket entering the lantern at an angle.
The lantern is constructed of cast aluminium, whereas older lanterns of this type tended to be cast iron.
Two Vulcanised India Rubber (VIR) conductors emerge from the open end of the bracket.
The 'wings' of these lanterns are removable, and each of the six glass reflectors attached to both wings are held in place with lead clips.
Many of the reflectors are missing, where they have fallen out of the lantern. The Edison Screw lampholder is still present within the main lantern body.
Around the other side of the pole is a cast enclosure for a Horstmann time switch.
A sales point that GEC made about the mirror reflectors was that they could be replaced easily in the event of loss - someone ought to do that, and bring the lantern back into operation!
