I suspect the real concern is there would be a push to relax the restrictions once the industrial facility has been built. Astronomical observatories have faced such problems in the past, to the point where research goals had to be fundamentally altered or where they ceased to be research facilities.

That said, if the goal is to reduce the lighting to the point where it has no impact, one has to ask: what is the point of having lighting at all? I suppose lighting could be restricted to indoor use only, but most commercial operations will expect some outdoor lighting.
