Are fluorescent light bulbs really worth the extra cost?

Have you noticed the new fluorescent light bulbs and wondered if they really are worth the extra cost? Actually they do save money. Here's how:

• They are more efficient, because they use only ¼ to 1/3 as much electricity as a standard light bulb.
• To ensure maximum savings, first replace the bulbs that your family uses the most.
• They last 10 times as long or about 10,000 hours.
• Check the packaging of the CFL to make sure it will work in your fixture.
• There are a variety of CFLs available. Make sure and pick the correct bulb for your home’s needs.

The biggest drawback to these bulbs is the "sticker shock". Since they may cost as much as $15.00 per bulb. But, they will last from three to seven years (10,000 hours). The savings in electricity could pay for the higher price tag in about one year, and would save an additional $20 to $40 for the entire time it is used

Use the following chart to match your current bulbs’ usage with the corresponding CFL:
