Energy Star Guide on CFL's
 

For anyone interested who's never seen this before, here's a really helpful site on CFL's, including how to clean one up if it breaks, etc...
Compact Fluorescent Light Bulbs : ENERGY STAR

I use that page when I'm comparing new LED/CFL bulbs that are replacing an incandescent. I like the chart that states the lumens from incandescents of different wattages. Some of the new bulbs just don't put out the lumens of the incandescents.

good info on that site. Thanks for the link Higgy
