This is not verified, but I was recently told by one of the counter guys in a supply house (who claims to have taken a class about it) that when we install it into a fixture (fluorescent, HID, etc) its called a "lamp".
When my kid put a lamp in a "fixture" it plugged it up and we had to get a plumber.
I told him lamps go in luminaires.

A am still having problems with "luminaire" but I do use "lamp holder" for that socket you put lamps in.
Luminaires still sounds like one of those skinny tie singing groups from the 50s.
