4' on center? What's on top of the trusses that's spanning 4'? With
that spacing - a likely cost saving measure - it's unlikely there's a
lot of leeway in the load handling capabilities of the roof framing.
You'd have to frame a ceiling before you could cover it, and with 4'
between trusses that wouldn't be easy to do with a light structure.
The lightest ceiling I could think of would be the plastic corrugated
roofing stuff, and that would still sag a bunch with 4' spacing.

A hanging ceiling is very light and could likely be used. Don't know
about adding lights to it though. Check with your local code office.
No one here can tell you for sure.
