Fluorescent strip light (Bexleyheath DA7)

This light is suitable for a shed or garage. It's 4ft long and is 36W (equivalent to around 150W of tungsten lighting).
Just to be clear, it's the metal base including the electrics, as well as the tube itself.
I also have a spare 5ft tube but I don't know whether it works or not.
Cheers,
Rob
