Edison-style light bulb and CFLs

     Instead, they should use compact fluorescent lamps (CFLs节能灯).
3. "CFLs save energy and last longer. They can save money in the long run," said a British official. CFLs
     use 67 percent less electricity than the older bulbs. They last up to times longer. Scientists say that if
     everyone used CFLs, electrify use would be cut 18 percent. There would also be much smaller amounts
     of greenhouse gases given off.
4. But it's difficult to make people change their lighting habits. First the CFLs are more expensive. They cost
    eight times the price of the older bulbs. Many people don't like the CFL bulbs. They find it too bright. You
    cannot change the light of a CFL, either.
5. CFLs have been around for several years. However, the older lights still make up about two-thirds of total
    light bulb sales.
