I came across a blog written by Peggy Deras, CKD, CID about choosing a compact flourescent bulb that will cast flattering light. This is referred to as CRI or color rendering index.
You can read her article here Kitchen-exchange: CRI: The Road to True-Color Light Bulbs
Did you know that not all CFLs can be used with a dimmer and that some can not be used in an enclosed lamp? Peggy links to a wonderful page on the Enviromental Defense website that finds the right bulb for your needs. This is definitely a page to bookmark.
One last note, CFLs contain mercury (about 5 milligrams) and should not be thrown into your household garbage. To find out what to do first check the Earth 911 website (where you can find disposal options by using your zip code for everything from paint to televisions) or call 1-877-EARTH911 for local disposal options.
If you live near an IKEA, you are in luck, they offer CFL recycling bins in stores across the world. In their fiscal 2006 year, IKEA recycled 156,301 pounds of CFLs.
