We’ve written before about compact fluorescent light bulbs – a new type of bulb you can buy for your home that uses a lot less electricity than standard bulbs, and thus reduces pollution and greenhouse gas emissions. But are they all they’re cracked up to be?

Some environmental groups warn that the bulbs contain mercury, which can be toxic and difficult to clean up in the event of a broken bulb.

Researchers in England claim the bulbs can trigger migraines, epilepsy and lupus.

And a review panel assembled by the New York Times concluded that most CFL bulbs do not give off attractive light.

Though a step in the right direction, clearly there are still some bugs to work out of the bulbs.

We've discussed energy-saving compact fluorescent lightbulbs elsewhere on this blog. Now, Popular Science magazine has a round up of the next generation in low-energy lighting technology.

The website One Billion Bulbs want to help reduce pollution, energy consumption, and greenhouse gases by getting people worldwide to change their old-style incandescent light bulbs to new compact fluorescents. Their goal: one billion light bulbs changed.

They still have a ways to go. As of this morning, they were around 56,000.
