Lamps almost always use lampcord as opposed to THHN due to the size requirements of the channels in the lamps (for instance chandeliers) It is cheaper, too.

THHN/THWN wire is internal to walls, box to box.
Lamp cord goes from the box/plug to the lamp.

It isn't out of the realm of possibility for THHN to be used in lamps. Like I said, there is a cheaper method, and most manufacturers will choose lampcord. Neither is wrong.

It's also worth noting that lighting fixtures are sort of the wild west when it comes to following codes and regulations. If you buy a name brand fixture from a good dealer it will be UL listed and use all rated internal components, including wire. However, light fixtures from antique/craft shops or random internet dealers there's a good chance you'll get either a homemade or imported fixture that is not UL listed, and who knows what kind of materials they used. Additionally they may use one prefab UL listed component, like a cord or bulb holder, then from that try to imply that the entire fixture is UL listed.
