A general rule when buying CFBs is to choose a wattage that's about one-third of what you usually buy. The table below shows some typical wattage conversions:
- 25-watt incandescent = 7-watt compact fluorescent
- 40-watt incandescent = 11-watt compact fluorescent
- 60-watt incandescent = 15-watt compact fluorescent
- 75+-watt incandescent = 18-watt compact fluorescent
CFBs are available in a huge variety of shapes and sizes, so you should have no problems finding bulbs to fit any fixture in your home. If you have a unique or unusually-shaped lamp or fixture, take the existing bulb along to the store to compare sizes.
