Reminds me of my father telling me how Ford changed the lighting in the first week after taking over Briggs Motor Bodies Ltd in Swathling, Southampton.

The plant was originally an aircraft factory owned by Owen-Cunliffe Aviation at the Southern end of Southampton (Eastleigh) Airport that Brigg's bought to supply Ford in 1949, Pre WWII Owen-Cunliffe built aircraft, during they were part of the Supermarine Spitfire supply chain shadow factory network in addition to aircraft servicing and airframe investigation, including German aircraft (photo's online {https://www.key.aero/forum/historic-aviation/145437-trying-to-identify-heinkel-111-at-eastleigh} including a damaged Heinkel among damaged Hurricanes show just how few incandescent lamps were hung in the buildings).

When Ford took over in 1953 the high hung poor lighting which left many dark areas where a worker could hide (and sleep) was replaced with lower hung florescent tubes in 4 tube bays end to end length ways over the entire factory floor and no more than 10 feet apart across the width, now the entire workspace was brightly lit. Ford also installed high level walk ways, most enclosed with shuttered later mirrored windows, so management could walk unseen to monitor the workers below, performance of time and motion studies being high on Fords agenda. The factory was closed in 2013 with Ford chasing EU subsidies and cheaper labour moving production mainly to Turkey, with the buildings being demolished by the end of 2017.
