http://www.startribune.com/business/201357281.html?refer=y In March Home Depot started a promotion with Cree and local utilities in which a 40-watt equivalent LED bulb is $9.97, and 60-watt bulbs are $12.97 and $13.97.
“As long as the new bulb gives off light like a traditional one, I’m fine with it,”
The new bulbs from Cree look and light more like an incandescent than LEDs of old. And unlike nearly every other LED bulb, they can be placed in enclosed fixtures.
After only 10 days, Home Depot’s online supplies were sold out twice, local stores have had to reorder and the retailer asked Cree to increase its production, said Mark Voykovic, Home Depot’s national light bulb merchant.

A CFL puts out 65-69 lumens per watt,a 27 watt puts out 1863 lumens,close to a 100 watt incandescent at 1550 lumens.

$12.97 for a "warm white" 60-watt equivalent, providing 800 lumens of light for 9.5W of electricity, at a warm color temperature of 2,700K
$13.97 for a "day light" 60-watt equivalent, with 800 lumens of light at a cost of 9W of electricity, at a cooler color temperature of 5,000K
$9.97 for a "warm white" 40-watt equivalent, with 450 lumens of light for 6W of electricity, again at a warmer 2,700K.
For comparison, a typical 60-watt incandescent provides about 860 lumens, and you can get 900 lumens out of a 14-watt fluorescent, so they stack up pretty well there.
--------------------
So by my muddy math a 60 watt incandescent uses 60 watt
A 60 watt equivalent CFL uses 14 watts
A 60 watt LED equivalent uses 9 watts or so.
