Benjamin Duoflux Lantern Installations

This flood light is one of the common "shovel flood" designs from the 1930s (this one was released in 1932 specifically). They produced a cut-off light-distribution, owing to the lamp being located within the reflector, but it was shaped in such-a-way as to project light forwards and downwards. These would run GLS lamps.

Birmingham

Bambi Air off Thimble Mill Lane has one installation of a Duoflux floodlight atop a column.

An unusual pipe-bracket exists up there too, perhaps the flood light was not the only thing installed up there.

The lamp has been smashed in this example.

On the site of the old Wolseley Works off Drews Lane existed a set of stunning installations, but nowadays just one of these remains. The one that remains is on borrowed-time, as construction of a new building has commenced, which wiped out all of the others.

Despite the newer floodlight on the same column, it is believed that both remained in use until the land became abandoned, as they are both facing different directions. The shovel flood took charge of lighting the previous site's entrance.

An elliptical lamp is installed inside - perhaps SON or MH.
