My detached garage with metal siding has 2x4 trusses spaced 4 feet on

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.

This is a 30 x30 garage with a metal roof. I think it is a 3 or 4 12
pitch. My ideas was to add 2x4's every 4 feet between trusses and use
7/16 osb for a ceiling. If everyone here thinks it might sag or is a
bad idea, I thought abotu using 4x8 insulated panels? I wonder how
that would look?

Without information on what the bottom chords of those trusses were
designed to carry, it's stupid to guess. The suggestion of a
suspended acoustic ceiling is about the only thing I would not have
any qualms about, and that would depend on how many light fixtures you
were going to install in it.

If you can determine who built the metal building, you'd probably be
able to find out the load information on the trusses.
