Environmentally-Friendly Light Bulbs

The NY Times has a good article about Walmart trying to sell more environmentally-friendly light bulbs, but meeting a variety of obstacles: Wal-Mart Puts Some Muscle Behind Power-Sipping Bulbs (via Slashdot and Metafilter).

I have one of these light bulbs (given to me by Seattle City Light) and its lasted at least 18 months (and it's in a lamp that is on most of the time that I'm home). Unfortunately, I still have 3/4th of a package of regular light bulbs to use up before I get more.
