65% to 75% less electricity

How to switch to compact fluorescent light bulbs 

Switch to energy star light bulbs and start with the most used light fixtures at home. Place compact fluorescent light bulbs in hard to reach light fixtures, such as ceiling fans, because CFL light bulbs can last up to 10 times longer than traditional bulbs. You won't have to worry about using a ladder to reach those light fixtures for a long time.

Choosing energy efficient light bulbs

Energy saver light bulbs work differently than traditional bulbs. So it should come as no surprise that selecting the right CFL light bulbs for the right fixtures requires different considerations.

Before selecting a CFL light bulb it's important to note that the type of lamp or lighting fixture (and whether the fixture is indoors or outdoors) can be very significant.

For example three way sockets do require certain types of energy efficient light bulbs. Dimmable CFL bulbs are recommended for dimmable fixtures. These important details are almost always provided by the manufacture, if not be sure to inquire before purchasing.

CFL bulbs and Watts

The incandescent light bulb has been around since 1872. And because we all have gotten use to using them, there is a tendency to measure light by wattage.

The number of watts, or wattage, is only a measurement of how much electricity is being used. And part of what makes energy star light bulbs so efficient is the fact that compact fluorescent light bulbs use considerably less watts, or electricity, to produce the same amount of light.

CFL bulbs and Lumens

The amount of light that any bulb produces is measured in lumens. The beauty of these energy efficient light bulbs is that they uses less electricity to produce the same amount of lumens, or light, than a traditional bulb.

This should be considered when replacing traditional bulbs with CFL bulbs. Remember this general rule of thumb, energy saver light bulbs use about one third to one fourth the wattage (electricity) to produce the same amount of lumens (light).
