There is no such thing a "12-3 THHN".


Someone else wrote "pull 12-3 w/ground THHN". Is that more acceptable

The ballast in each fixture must be wired in parallel with respect
to all other ballasts on the same circuit the same way one wires multiple
incandescent fixtures on the same circuit.

wires, grounds extra. The picture is helpful. Thank you.
