| So, for now, I just stuck a 100W incandescent in it. I guess I'll just
| have to buy a new fixture.

Another option might be to get a 70w halogen.
They're now available encased in an incandescent-
style outer shell, to fit an incandescent fixture.
The 70w H is supposed to be equivalent to 100w
incandescent. I use them now for work lights. The
LEDs are getting better and cheaper, but I don't
like them as well for seeing detail.
