This chart shows the number of lumens produced by common incandescent bulbs. If you're looking to buy a bulb that will give you the amount of light you used to get from a 60-watt bulb, you'll now look for 800 lumens.
You can use lumens to compare the brightness of any bulb, regardless of the technology behind it, and regardless of whether it's a halogen incandescent, CFL or LED. Using lumens helps you compare "apples to apples" when you shop for light bulbs. Once you know how bright a bulb you want, you can compare other factors, like the yearly energy cost.
