I guess I would say that as an inspector, I'm looking for something that says that this luminaire must be connected to a circuit with 90° C conductors and if it doesn't say that, case closed. If it says "to be terminated on a 90° conductor" than thats what I look for on the inspection. The problem usually is that electricians are connecting luminaries that specify 90° C fixtures wires are to be connected to 90° branch circuit wiring and the branch circuit wiring is a conductor with 60° insulation rating. Quite often these luminaire replacements never get inspected.
