Q: My CFL bulbs burn out quickly. Why?
A: All CFLs that meet the US Environmental Protection Agency's Energy Star label are required to carry a two-year warranty. But, if your bulbs are burning out prematurely, a few things might be the cause.
  • Turning a CFL on and off too frequently. It is recommended that CFLs remain on for 15 minutes at a time.
  • Using a CFL in a vibrating fan or using a standard CFL on a dimmer switch.
  • Using CFLs in enclosed fixtures. If a CFL does not have airflow, its lifespan may be shortened by as much as half. However, this is still five times longer than the life of an incandescent bulb.
  • Exceeding the recommended wattage. It is important to read the label.
Q: I've tried fluorescents and they are either too harsh, too dim, or flicker. Why?
A: CFLs have come along way in recent years. A variety of light colors are now available to produce a more natural light. CFLs will be as bright as incandescent if the proper wattage is used. The newest generation of CFLs rarely flicker.
