Holophane Wallpack Lantern Installations
These bulkheads bear a strong resemblance to their sister bulkhead, the Wallpackette. These are a decent bit rarer (or not payed attention to) than those as they weren't used on such a wide scale, but they were known to run 50W-150W SON-T or metal halide lamps when they did appear.

This LED retrofitted example was spotted off Dale End. It is not the only one here, and all of them seem to be retrofitted in the same way.

Lichfield
This installation is located along Minster Pool Walk.
It is fed via an AC Ford cut-out box on the wall above.
Inside the box will be an isolator. This example has been sheltered from the weather by the building and an adjacent tree, so the Wallpack is in remarkable condition.
