"William Sommer****** is Wrong Again"

Suppose a 100W-equivalent CFL that draws 25W lasts only 1000 hours. In
that
time you save 75kWh. At 10 cents per kWh, that's $7.50 -- three times the
cost of the bulb.


** A CLF that genuinely replaces a 100W bulb cost at lot more than $2.50
where I live.

Even a "no brand" 27W CFL ( direct from China import ) sells for $ 8 to
$10 each.

I worked out long ago that the break even point for a CFL occurs at about
1000 hours - but only about half of them make it that long ,without dying
or losing almost half their light output.
