Hi @Trizzoop, here is a link to my other topic that has the light information in it.
If you start around post 64, that was my original build (which has since been tripled).
I believe at this point, my light draws about 450w from the wall. It totals 42 bridgelux strips and three drivers.
On the other questions, I’m not a light expert, @dbrn32 helped me out a lot, he may chime in on those…
