What is the highest wattage incandescent bulbs made, that will fit a
standard socket? Normally the highest I see in most stores is 150W.
But I used to work at a school and they had 300W bulbs in their lobby
fixtures. I seem to recall seeing 500W bulbs when I was a kid in the
60s. But it seems to me they may have had larger bases.

I am asking this because I just want to know, but also because I am
wondering how high the compact florescents will go. I just saw a CF
bulb that claims to be equivalent to 150W but uses 42w.
