PSA: CFL's pose mercury hazard - do not throw into trash
I didn't know CFL's pose a mercury hazard.
I've had one that was dead out of the box and one that didn't last a week

OK, time for Super LED bulbs.
Is there anything hazardous with them?
3-27-2007 Mercury in energy-saving bulbs worries scientists
Mercury is poisonous, but it's also a necessary part of most compact fluorescent bulbs, the kind that environmentalists and some governments are pushing as a way to cut energy use.
With an estimated 150 million CFLs sold in the United States in 2006 and with Wal-Mart alone hoping to sell 100 million this year, some scientists and environmentalists are worried that most are ending up in garbage dumps.
Mercury is probably best-known for its effects on the nervous system. The Mad Hatter in the classic children's book "Alice in Wonderland" was based on 19th-century hat makers who were continually exposed to the toxin.
Mercury can also damage the kidneys and liver, and in sufficient quantities can cause death.
"Disposal of any mercury-contaminated material in landfills is absolutely alarming to me," said Lindberg, emeritus fellow of the U.S. Department of Energy's Oak Ridge National Laboratory.
The mercury content in the average CFL -- now about 5 milligrams -- would fit on the tip of a ballpoint pen, according to the U.S. Environmental Protection Agency, and manufacturers have committed to cap the amount in most CFLs to 5 milligrams or 6 milligrams per bulb.
The majority of Philips Lighting's bulbs contain less than 3 milligrams, and some have as little as 1.23 milligrams, said spokesman Steve Goldmacher.
RECYCLING HURDLES
One problem with recycling is that it isn't cheap.
Another obstacle lies in the fragility of the bulbs and their mercury content.
"People who are going to accumulate these things from the public are going to have to address the fact that breakage will happen,"
State laws are also a factor.
Federal regulations mandate recycling of fluorescent lighting, while exempting households and other small users. Some states, however, are strict. For example, California no longer allows anyone to throw CFLs in the trash, while Massachusetts requires manufacturers to implement recycling programs and meet certain targets.
As technology advances, however, mercury could become less of an issue, at least as far as light bulbs are concerned.
Last month General Electric Co. said it was working on doubling the energy efficiency of incandescent lights and eventually developing versions comparable with CFLs. These bulbs, which the company hopes to begin marketing in 2010, will cost less than fluorescents but they won't last as long.
Meanwhile, some environmentally minded consumers are embracing CFLs and doing their best to dispose of them responsibly.
"I have CFLs throughout my house," said Lindberg, who lives in California. "None of them have burned out yet. I can't tell you what I'll do with them when they've burned out, but I won't throw them in the garbage."
