It's a wood shop. There are workstations throughout the space --- table saw, band saw, drill press, router table, chop saw station with outfeed tables, radial arm saw, large workbench on casters, base and wall cabinets for storage, etc. 9 foot ceilings except a long soffit on one side about thirty five feet lowering the ceiling to about 7'6".
Thanks to the poster with the link to the lighting calculator. I believe that is what I need.
