Only seen one collapse - vivosun 8x8
Smaller tents are not likely to do it , as long as it’s a standard light, it’s good. I’ve hung 2 light, van, filter and still been good
I got a super heavy light and a really cheap tent and I'm fine just, haven't even seen any flex...They're designed to take the weight of a light and I'm sure yours isn't that heavy
All depends on the mounting bar style and clamps of the tent. If you're scared you can always upgrade AC Infinity has rigid steel for more weight and heavy usage.
