...answer this Q....

I am installing new lights in a 1950s house. The lights have the warning regarding using 90°C rated wire (NM-B). The house is obviously not wired to that standard. If I install the new lights, do I need to wire NM-B all the way back to the breaker? (I guess the sub-question is: is it the light itself producing the heat requiring the NM-B (in which case a short run of NM-B away from the ligth will suffice) or is it the electrical draw itself in which case the whole run should be NM-B?)
Thanks in advance for any help.
