Incandescent VS Compact Fluorescent Light Bulb

Until recently there have been some drawbacks to compact fluorescents. They come on a wide variety of sizes, shapes and wattages, so you may have to shop carefully and try several bulbs before you find exactly the right one for your purpose, one that fits your fixture.

One on the biggest consumer complaints in the past has been that compact fluorescent light bulbs couldn't be used with dimmers. That problem is being solved now that there are dimmable compact fluorescent lights on the market and energy-efficient torchieres being sold today that feature either fully dimmable compact fluorescent bulbs or three stages of brightness.

And finally, in the past some lower-cost compact fluorescent bulbs have been imported and sold in the U.S. Many of these have been of questionable quality and had a lifespan much shorter than predicted. As a result, many people who tried compact fluorescents have been unhappy with their performance.

Here's a rough comparison of the long-term costs of the two types of light bulbs:
