Compact Florescent Bulbs! A Great thing for the enviroment (Be Green!) and also a money saver in the long run. MOST say they last 7 years! If that is true, over the life of the bulb it is a saver. Also, it is helpful in the summer as your home is cooler as old bulbs are hot! CFBs are not! Also, It takes a LOT less energy, as we all know to run them, saving on your energy bill. NO it isn't going to save you $100s of dollars but still dollars! I like to save everywhere I can, even if it is change, and what an awesome thing to help the environment in the long run! Not a bad deal!
Yes, we have them in every room of our house!
