Yes, so long as you aren't actually drawing more than 100W.


I wouldn't sweat the "drawing more than 100 watts" part. Really.

Think about it: I'd feel safe betting that *almost all* light fixtures
(sockets) are electrically capable of handling far more than their rated
values in watts. Many standard Edison-base light sockets are rated at
660 watts.


I once saw a "bankers' lamp" style desk lamp rated for 60 watt tubular
"T10" bulbs produce a slight burning odor and have wire insulation
slightly char with a 60 watt bulb. It was plenty fine and dandy with a 40
watt one.


Yes.

Just to make the point excruciatingly clear, at the risk of beating this
already-dead horse to death: even though the ratings have little to do
with the amount of current drawn by the bulb, I would never attempt to
exceed those ratings, say by putting a 75-watt bulb in a fixture labeled
for 60 watts. In fact, as pointed out by your example, it would be
better to err on the side of caution, especially if in doubt. If the
fixture says 100 watts, use a 75 watt bulb, maximum.
