The battle of the bulbs

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.

A couple weeks ago I converted all my light bulbs at home to this style and can vouch that they give off great light. I haven't gotten my electric bill to see yet to see what I'm saving, though.

Nothing. A light bulb burns out when part of the electrical circuit is broken. If you try to send electricity into a burnt-out bulb, it will have nowhere to go.

Why do bulbs burn out? Bulbs work by shooting electricity through a tiny piece of metal called a filament. In an incandescent (traditional) bulb, the electrical energy heats the metal until it glows. In a fluorescent bulb, the filament shoots electrons through a tube filled with mercury and argon gas. The electricity energizes the gas. The tube is coated on the inside with a substance which glows when the gas transfers energy to it.

In both types of bulbs, years of carrying electrical current eventually weakens the tiny filaments and they break.
