Doing the math you get the following for max load through a given fixture:
1) 7.68A
2) 4A
3) 5.2A

That's by taking the max fixtures in a chain, remove one (because the we're finding the load that is passed through) and then multiply.  For the first this is (13-1)*.64A.

Once you look past the CYA lawyer stuff it's like most power stuff where you just have to do the math.  It's entirely possible that with staggered startup you could run more on a chain but they need to be careful of stuff like inrush current when you power up a whole chain at once.  I'd just go with what you can deduce from the manual.

Cool - thanks Erik. Makes sense. I am no where near the max then so should be good to go!!

With LED lights, it's awesome that you can pass power through. With my first LED cans, I actually modded them and added edison plugs on the back, wondering why nobody offered that as an option at the time.  With the stock 18 gauge power cables, you could string lots of lights together with no issue.

Yes, it makes wiring trussing so much easier…

And you can get shorter and longer IEC cords to use exactly your needs, even cleaner on standard setups.

Yes I try to keep them neat by customizing lengths. I usually make them to size if I cant find what I want stock.
