Not when another source of heat is a lot cheaper which it certainly is here by a
factor of about 3.

The 6 to 15 incandescent bulbs needed in the lifetime of a single CFL easily
exceed the cost of the CFL these days.

This absolutely hasn't been my experience.
4 of 20 of those expensive CF I bought lasted less than one year.
Still I think overall is a savings.

When did you buy them.
Some suffered the 'bad capacitors' fate.

Yes, I've had early failures, particularly on the first CFs I bought, but
overall the CFs are still much cheaper to buy - and continually being more
so as their prices drop and reliability increases.

You might be interested to know that the first CFLs I bought about 15 yrs ago
were among those with the longest lives I've ever had.
