Pentair microbrite light installation question

First off, I want to thank everyone on here for posted question and answers given.. I have learned so much, but still much left to learn. That being said, my wife and I are currently build our own. I’m just now getting ready to finish the electrical before the shotcrete stage and I have a question about the microbrite lights and their installation. I understand that I can use the 1-1/2” pvc for the housing in the wall, but what I am not understanding is according to the instructions from pentair, it looks like I need to also install what looks like a 1-1/2” npt(???)or a wall fitting. So is this wall fitting done after pool finish? If so, how would I get the threading over the 1-1/2” pvc if the conduit is locked in place by the shotcrete and finish?
I know that I am probably over thinking things here, but I am gluing up the conduit tomorrow for all of the electrical and want to make sure everything is in place before inspection and shotcrete. Anyone here ever installed the microbrite light in a new build? I appreciate any feedback.

The wall fitting is a 1.5 in female adapter/1.5 in flanged fitting that is glued to the 1.5 in pvc pipe. The threaded fitting is where the plaster will finish too, therefore wall fitting is done prior to plaster.

So if everything that I have read and talking with others, I would treat the light conduit like the plumbing return conduit and just extend past where ”finished shotcrete” and my pebble finish would be and trim back like the returns?

I have the same question. Do I need to add a standard return wall fitting like thishttps://www.yourpoolhq.com/hayward-sp1022s-wall-fitting.html

....Or will a standard plumbers 1.5” schedule 40 slip to FPT work?
