Lighten blend mode should work, if all three separate light images are overlapping they should blend. In my own setup I had overlapping lights as well.

Quick update - I’ve been totally working on other projects these past few years so sorry for being MIA! great to see this thread is still alive and well.

I did just buy a new house so maybe I will update all of this in the process and create something new here.

No. I didn’t solve the problem
