I've started migrating all of the light bulbs in my house to CF from incandescent.  As an incandescent blows, in goes its CF equivalent.  About 3 months ago, I replaced all of the lights in my bathroom with CF.  The cost and energy saving made me warm in my heart.  The color, however made me look jaundiced. 

Unhappy with the perceived color, I looked around on the web today for a comparison of CFs.  Thankfully, Popular Mechanics ran an article in May 2007 on The Best Compact Fluorescent Light Bulbs.

The punch line: N:Vision Soft White 19W (2700K) CFs are the winner in their roundup.  I'm going out today to pick up a bunch for bathroom #2.

Yeah, but what of the mercury used to generate the light?  Phoenix offers a great program for hazardous disposal (old paint, motor oil, etc) where you can bring these for proper disposal.  Ikea also offers a disposal program, and I expect Home Depot and Lowe's to offer them as well (if they don't already.)  If you want more information on mercury use in CFs, Popular Science also discussed this in a later article, Compact Fluorescent Bulbs and Mercury: Reality Check.
