Gee, it's so sad that you're not thinking.

You came into the discussion too late. Go back to sleep. We were
talking about using incandescent lamps as low powered heaters. Any
light produced is either a useless byproduct or an intermediate
step
in distributing the needed heat.

I got that, thank you very much. The question being discussed here is
the *efficiency* of CFLs at producing heat vs. incandescents, no?

No. They are *exactly* the same. Both are 100% efficient at heating.

So
what's your answer? I'm still not sure, but it seems to me that
incandescents are more "efficient" in that way--in other words, more
of
their energy gets converted to heat than light, proportionally,
compared
with CFLs. Right?

No, all energy use results in heat; 100W in = 100W out. When the
light
strikes an object, that which doesn't get reflected heats the object.
