MoRe: Tilting At Mindwills... GOTCHA !!!

That did not work, either. And, again, I cannot see why...

Needed a nap to clear migraine...

But, after back-tracking and [b][i]again [/i][/b]trying several free or budget 3D editors, I [b][i]accidentally [/i][/b]found how to delete vertices etc in Blender. (BFA fork.)
{ Mutter, mutter, [b][i]ijit UI[/i][/b], mutter, mutter... }

So, I took the lights + panels + strip that I'd previously extracted, ripped it back to just the six shallow 'cuboids' of the luminaires. Saving them as an OBJ, I used find/replace in free Notepad to tweak 'Y' coordinates. Moved them down just enough to clear the originals, re-saved.

With the main scene OBJ loaded at ~25% original, I soon masked its desk lights and bulkhead lights, dialled them to super-ambient etc. I loaded in the modified luminaires' OBJ at same scale. Used XYZ translate to align just below scene's luminaires.

I made the room door transparent to get a fair camera angle, ran a test render and cheered. 
 :yeah:  :yeah:  :yeah:  :yeah:  :yeah: 
Full render currently running on 'Box'...

It is a win. Even if took injury time, extra time, a 'tactical substitution' and penalties...
