I put 12 of the Costco Feit's in my 30 x 40 barn. The ceiling is white but not the walls yet. It looks like daylight. I got the 4000K as the 5000K are just too bright as they tend to blind me. Now you can daisy chain them. They were either $20.00 or $30.00 each.
Sorry I currently have 9 in and 10 when I'm done. Had to subtract 2 for obstacles. But it still looks like daylight. A nice addition to any garage or barn. ps I bought a couple at a time so it wasn't bad on the old pocket book.
