best price I found at a glance is about $30ea for 100w high bays

https://www.amazon.com/dp/B07W9KZ1TC/I have a LOT of conduit on the ceiling for all my current lights, which isn't going to do me much good I'm thinking. Need to figure out a full plan and arrangement before pulling trigger on any quantity more than just a sample. I could remove a bathroom from the shop and pick up a fair bit of space if I wanted to and that would affect the lighting plan as well.
I think I need to do some sketching.
Found a bird entry point, need to get some foam.
There's a small gap around the vent stack for the paint booth. It's a floating stack through a hole in the roof, with a wide storm collar 1.5-2" clearance above the roof collar, and then about 2" between collar and stack. I wonder if I could pack that with stainless steel wool or something? I don't see anywhere I could chicken wire around it without potentially causing roof issues, and I'm sure it's a floating stack for a reason.
The cover on the stack was also askew - have to secure that properly. One side was bailing wire one side was out of place and insecure (it's a center hinge double damper thing)
Rubber roof on the old shop looks recent and excellent.
