kok328, I actually had a run-in with this actually trying to find a light kit with standard base sockets. I was not aware that they not only stopped making bulbs greater than 60W in an intermediate or candelabra base, but that you cannot get fan light kits with a standard base for just the reason that they do not want you to be able to put a higher wattage bulbs in them. I'm guessing quite the number of houses burned down. I had been trying to find a standard base light kit to replace one that didn't match the second fan in the room. Every time I looked, they were all candelabra and one miserably beat up box with a standard base in it I didn't want to touch. Once I finally found someone to help, he told me about the changes. I snagged that ratty old box right quick!
It's not that I intend to use greater than 60W--in fact I almost never even use those lights--but I just don't want to have to keep a gazillion different kinds of lightbulbs around.
FYI, the guy pointed out how easy it was to replace the sockets in the fixture should I have the need down the road...
