I'd gone through two different sets of lights in my shop before getting the 35,000 lumen ones I recommended in my first post above. I started with 70w CFL bulbs in high-bay reflectors, then converted those the LED corn bulbs, and finally swapped to the LED UFO lights. The shop was never truly fully lit until I installed the UFO lights. It is now. I'll try to get you a picture or two. So you can see for yourself. My ceilings are 12' with a large 16' x 10' door. I installed the lights along the sides of the door (one on each side), and three across the 30' width in the space not covered by the door and that worked perfectly for me.
