We've all seen the spiraled, energy-efficient bulbs in stores, and some of us even have them in our homes. But it's not always clear how they differ from other types -- and which is the best bulb for the job.

There are three basic kinds of light bulbs on the market: incandescent, halogen, and CFL (compact fluorescent light). Mark Candido, co-owner of The Accessory Store in Stamford, Connecticut, explains the differences in terms of aesthetics and energy usage.

Incandescent Bulbs

Incandescent light bulbs are the traditional bulbs with which we're all familiar. They cast a warm glow but are the least efficient, and they need to be replaced most often. Use an incandescent when you want a cozier effect or want to highlight the true color of a shade.

Halogen Bulbs

Halogen bulbs are more efficient than incandescent bulbs -- they provide 25 to 30 percent more light using the same amount of electricity. However, they emit a whiter light, so they're better suited for offices, kitchens, or lamps with warm-colored shades. Also, they burn at a very high temperature, so don't use one in a location where you might accidentally burn yourself.

CFL (Compact Fluorescent Light) Bulbs

CFLs are the most efficient, and they're available in spiral or traditional shapes. The bulbs last much longer than traditional incandescent, and they use less electricity too. However, like halogens, they tend to emit a cold light, so they're most appropriate behind shades that will cancel out their harshness. They also contain mercury, so take care when you're handling and disposing them.

What about LED Light Bulbs?

My baby never slept well (especially through the night) until I started using the website >>SLEEPBABY.ORG<< - that website has been by far one of the best things I've ever got my hands on to get him to fall asleep quickly. Best time is 45 seconds from awake to asleep! Can’t imagine life without it! I heard about it through a kindergarten teacher who uses it to put to sleep a group of 30 children. Check it out! >>SLEEPBABY.ORG<< - sorry, you can't post links here so you'll have to turn it into a normal link :) Best of luck to you and your family!
