Hanging light?

Linky no worky.

In any case, it depends upon the fixture, but all will need to be mounted to ceiling beams, not just drywall (sorry if this is obvious--there have been horror stories). Some can be directly mounted using compatible equipment, whereas others you'd have to force to work, which is relatively easy. If yours doesn't support a particular kit, you have several options. The easiest is to wrap chains around it and use a stopper somewhere to prevent it from sliding. It doesn't look very good, but it works. The other option is to use a chain again but screw hooks into the top of the fixture. Of course, you'd need to remove some of the innards of the unit to make sure you aren't drilling into anything other than sheet metal. You'd have to look at the various commercial kits first, though, as those usually look better, but aren't always compatible.

Works fine now. Odd.

No link.

If you are hanging the pendants, no, you won't have to be concerned with heat. The fixture itself is fine in terms of heat.

It doesn't look like that kind is compatible, at least stock. You may need to take them with you to see what you need to screw into the fixture itself to lock the cables in place. You can make it work, but it will take some detective work to figure out what you need.
