As titled, I'm planning on installing a new 15A lighting circuit for my unfinished basement with 6 new 40W LED fixtures. The fixtures themselves are direct wire and UL listed. The diagram I drew up for the plan is below. I have 1/2" KO cable clamps for the Romex running between each light, which I plan on running in the rafters (drilling holes as necessary). You can assume all ground conductors will be interconnected and running back to the load center.
I'm looking for a review of my diagram by those who know more than me. I just want to make sure that I can wire up the switch the way I have drawn, with it sitting sort of in the middle; I'm trying to be as efficient as possible with the routing of 14/2 and 14/3 Romex.
