I am on Toledo Edison (one of the top three highest electric utilities in the US) and my bill has dropped $10-15 per month since I switched to compact fluorescents about four years ago. I have had problems with many of compact fluorescents that are greater than a 75W incandescent not lasting very long at all. These were purchased at Wal-Mart and Lowes. The bases seem to get hot and burnout, even the ones in my cool basement. I recommend using the full spectrum/natural light type. The light is so much better. Lately, I have been purchasing all of my compact fluorescents at 1000bulbs.com. So far all of the bulbs from this place have lasted. I believe that you have to make a minimum of a $40 order with this company.
