Holophane Wallpackette III Lantern Installations
With an IP rating of IP65, the Holophane Wallpackette III is a robust bulkhead which is now sold in LED form. A polycarbonate front-cover occupies the lanterns as standard, with a rigid diecast aluminium body. They are decently-common throughout the UK, seen in areas such as subway systems, car park lighting, amenity lighting and more.

This horrendously-yellowed installation was sighted on a building just-off Whittall Street. Judging by the state of that refractor, it could be a SON example. That or it has just spent too long being exposed to direct-sunlight.
