And threaded rod is?
...what weight, you did not list any? I've used jack chain to support fixtures, NEC legal.

There is not much in the NEC about supporting fixtures, 410 is pretty short. Local building codes are likely a better source.
As far as hanging 100' of flouesents with jack chain- I have no problem with it as long as you use more than one piece on each end.

Most 4 and 8 foot strips come with knockouts for S hooks, why would you have an issue with chain?

Typically if you use jack chain you do not use strut. You put the first 8' fixture up with two jack chains located 7' apart and from that point on you add a jack chain every 8' so each jack chain only supports the weight of one fixture.
The number 12 jack chain we use has a 25 pound working load limit.
For a nicer look use aircraft cable in place of jack chain.

If they were directly secured to a surface, I would bet whatever fasteners used still are not listed.

Exactly, and there is no general requirement that anchors, fasteners or supports be listed.
Oh, come now, usually I just get some old bits of shoelace and use however much I have until it looks like it won't fall.
