TL;DR
Luminaire support is the code-required mounting that carries a light fixture's weight independently and securely, from listed outlet boxes good for 50 pounds to fan-rated boxes, hickeys, and strap kits for chandeliers and heavy pendants. NEC 314.27 and 410 govern what each box may carry; fixtures over 50 pounds must be supported independently of an ordinary box.

Inspectors check this at trim-out, and failed ceiling fixtures are a classic result of skipping it.
