While compact fluorescent lightbulbs do not quite have the longevity that we were promised, they still beat incandescent light bulbs by a mile. They also use a fraction of the electricity that incandescent bulbs needs, and thereby cut your energy bill.  You can also pay a little more and get the LED bulbs.  The LED bulbs are more energy efficient than the CFLs and will last as long as 20 years. So think about the impact upgrading your lightbulbs could have on your home.  Going with CFLs or LEDs may cost a little more upfront, but the energy savings will be worth it in the long run!
