Thanks, guys. It's been fun playing around with the space. It's a lot easier to change things now than later.
I went to the shop after it got dark last night and ran a couple strings over the top, at about the ceiling height, and hung my LED lights up. Doing this allowed me to see that I needed to order 2 more lights.
I agree, BrianW. I gave them a hard time about those.
It will be an easy fix though. Just drill out 2 aluminum rivets on each box and slide a plug in the holes.
