"A Nation of Dim Bulbs"

Here.

Excerpt:

There are other complications that might give environmentalists pause, if they were the kind of people who paused. When a CFL bulb finally dies--after years and years and years!--it cannot be dropped in the trash like an incandescent; it must be recycled by specially equipped recycling facilities. CFLs contain mercury. If one breaks in your home, Kazman says, EPA guidelines suggest you open windows and leave the room for at least a quarter of an hour before trying to clean up the mess. And for God's sakes don't use a vacuum, which could disperse the poison into the air. Even when they're intact, U.S. News happily tells us, "the bulbs must be handled with caution. Using a drop cloth might be a good new routine to develop when screwing in a light bulb."
