Shop Lighting advice wanted/helps with my employment. 3 bay layout, with GIANT I beams coming down lower than lights mounting location
There are literally dozens of lighting calculators on the web. I'd just use one of them, I did. They will ask how much light you want. In my shop I went for 75 lumens/ft2. For a 40' X 25' bay, this required 15, four bulb LED fixtures. Power consumption? Multiply the current draw per fixture by the number of fixtures, multiply by 1.25 and you have your current requirement. #12 copper is rated for 20 amps, #14 copper is rated for 15 amps. If you are using conduit, you may have to derate the conductors, see the NEC for requirements. This is what my shop looks like.
