I am in the process of putting together a new shop. For lighting, I used LED 60w equivelent lamps that actually use 10w each. They are type that emulate a standard A-19 incandescent "bulb". I used old school porcelain fixtures mounted on 4" octagonal ceiling boxes; total cost per lighting point about $15 (not including wiring). I put 12 points in the 600 sq. ft. main room and 9 in the 300 sq. ft. ancillary room. Of course I have supplemental lighting at some machines. With a total load of 210w to light 900 sq. ft., instant on, 20+ year life and a pleasant color temperature, I am vey happy with the LED lights.
