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?

But your local code enforcement will have the final say on whatever is
acceptable. I'm going to guess that you're in an area where you don't
get snow because that method could never meet roof snow-load
requirements up here. So if you are in an area that gets snow, I think
you're in trouble before you even start. If you don't have the design
specs for it, you might need an engineering assessment just to pass code
as it is. Don't take chances because they could make you tear it down.
And like I said, the local code office will have final say on
everything.
