ElZappr,
I believe that NM-B cable, which became available around 1985, is suitable for these fixtures due to the 90 deg. rating as long as it's ampacity is determined in accordance with the 60 deg. column. Pre-1985 NM cable would not be suitable due to the lower temp. rating.
Same thing with most of the surface mounted ceiling fixtures being sold these days.
