Enormous old fitting in Stanley Dock Tobacco Warehouse in Liverpool

Another pic that came up on facebook that is too good not to share! This is in the old brick tobacco warehouse in Liverpool, said to be the worlds largest brick warehouse. I remember passing it late at night sometimes in the late 80s and seeing cool white fluorescent light shining through dirty windows on the ground floor/basment and always imagined the light comming from a load of old BC fittings.
