I just did an electrical overhaul in my shop including new subpanel, outlets and lights. I went with 8' LED tube fixtures. They take 4 4' bulbs in each one.

Here are the fixtures I bought: https://www.1000bulbs.com/product/192389/PLT-20015.html

Totaled about $60 per fixture.

I am a little over 100 lumens per ft where I put the fixtures. I am very happy with them.

Wiring was pretty easy and they hang down about 6" from the ceiling. You could mount them directly to the ceiling but I had some stuff in the way so I just went with suspended.
