I used Lithonia direct wire LED flat panel fixtures with 0-10v dimming and wired them up with 12/2 Armored cable with 16/2 signal wire bundled into the cable. I assume if you use a plug in fixture that you will run a separate signal pair to control the dimming? Just curious.
Not sure how many you ordered but FWIW I used 16 of these 15k lumen, 5000k fixtures in my 40x40. They are hanging around 15 1/2'. I don't have any shadowing.
