Below are some points to concider before you purchase Energy Efficient Bulbs. Make sure they are the right ones for you, your home, and the purpose they are to be used.

1. Start with one bulb.

There are lots of choices, so before switching all the bulbs in a room, try just one to make sure it gives the kind of light you want. Look for bulbs with a color temperature between 2650 and 2850 degrees Kelvin or labeled "warm white."

2. Know your watts.

Look for a CF bulb whose wattage is about one-quarter of the incandescent you're replacing. For example, a CF bulb in the 15-watt range replaces around a 60-watt incandescent.

3. Check the shape and size.

Both the CF bulb and its ballast (between the glass and the screw-in part) can be bigger than standard incandescent bulbs. Inspect your lamp or light fixture to make sure it can accommodate the CF bulb.

4. Be careful choosing CF bulbs to use with dimmers.

In order for a CF bulb to work in a dimmer, it must be specially designed to do so. Read the package before you buy a CF bulb for a dimmer-controlled fixture.

5. Look for Energy Star.

The most energy-efficient CF bulbs carry the Energy Star label, the imprimatur of the government-backed energy efficiency program.

6. Dispose of burned-out bulbs properly.

All fluorescent lights contain trace amounts of mercury. But don't worry — there is far less mercury in CFs than in thermometers or old thermostats. Plus, using these bulbs helps prevent mercury from being released into the air from coal-powered power plants. When they burn out years down the road, recycle them. Visit Recycleabulb or Earth911 to find your closest recycling location.

7. See if your utility offers rebates.

Energy-efficient bulbs help utility companies lessen their load at peak times, so sometimes they run special programs or rebates to encourage you to make the switch.
