I started with 2 single bulb fixtures in my 22x22 garage converted to a shop.  We don't have enough amps in the old sparkle box in the basement to go to crazy so I went with a chainable 3 ft LED lights off Amazon.  There are 12 or 13 in total in the shop....I forget how many.  And even with all those lights I still have a couple dark spots.  My hand tool bench and table saw are lit REALLY well but my general purpose bench along the back wall not so much.  

It shouldn't be too much longer with this setup though.  We are getting a new sparkle box with 200 amp service when the solar gets installed.  Then its let the old bank account recover a bit and get a subpanel in the shop.  I will probably pull all my only lightning hoses and then have a professional sparky come hook up the sparkle boxes.
