CFLs vs incandescent "max wattage" cautions in overhead fixtures....

I assume this is a heat-based limit...
of course it is. Do you think the actual light causes the fixture to
catch
fire?
Although heat may and probably is the issue, over wattage through
current draw certainly could become a problem.
It *could...* if CFLs were made that drew over 60W. I haven't seen one
yet... heck, even a 48" T12 only draws 40W a tube.

Indeed...I figure as long as I compare apples to apples (watts to
watts), the issue if illumination values doesn't matter..
Thanks for the responses.
I would multiply CFL wattage by 1.5 (maybe as much as 1.75) for fixture
heating effect in comparison to incandescent, since incandescents produce
a lot of infrared. Most of that infrared becomes heat - in the room but
not in the fixture. CFLs produce little infrared, but mostly non-radiant
heat and visible light.

Even at 1.5:
I can rest easy :-)
Thanks
