Incandescent light bulbs.

Stock up!

UPDATE: Shining the harsh light of journalism on Arianna Huffington:

The light bulbs are the first incongruity I spot waiting for Arianna Huffington in the photo-laden living room of her Brentwood home, the one she bought for $4.1-million (U.S.) as an infamous new divorcée in 1997. The bulbs are old-time incandescents, not the compact fluorescents you might expect of someone who ran for governor of California against Arnold Schwarzenegger with the slogan “the hybrid vs. the Hummer.”
