In principio Stu dixit: “Fiat lux”

And there was.

I’ve been working on the lighting grid for the shed, based around 16 double fluorescent tube fittings.  The majority of the light reserved for the main workshop floor, with some for the mezzanine.

This is what I have come up with (excluding localised light which is available for the lathe and bandsaw).

I was thinking about the GPO grid, but that is probably better left for when the shed is up and the general layout is understood.
