Use Compact Fluorescent Light Bulbs Instead of Incandescant Light Bulbs             

If every American home replaced just one light bulb with an ENERGY STAR, we would save enough energy to light more than 2.5 million homes for a year and prevent greenhouse gases equivalent to the emissions of nearly 800,000 cars.

ENERGY STAR qualified Compact Fluorescent Light Bulbs:

• Cost from $4 to $15 each, but save you about $25-30 per bulb in energy savings over their lifetime, more than offsetting their initial cost. We recommend replacing the light bulbs in the fixtures you use most with ENERGY STAR qualified options, whether indoor or outdoor.
• Use at least 2/3 less energy than standard incandescent bulbs to provide the same amount of light, and last up to 10 times longer.
• Save $30 or more in energy costs over each bulb’s lifetime
• Generate 70 percent less heat, so they’re safer to operate and can cut energy costs associated with home cooling.
• In addition to other quality requirements, must turn on instantly, produce no sound, and fall within a warm color range or be otherwise labeled as providing cooler color tones.
• Are available in different sizes and shapes to fit in almost any fixture, for indoors and outdoors.

Where to Use Compact Fluorescent Light Bulbs:

• To get the most energy savings, replace bulbs where lights are on the most, such as your family and living room, kitchen, dining room, and porch. Fixtures incorporating multiple bulbs are an excellent place to start.
• Some Compact Fluorescent Light Bulbs have trouble operating in enclosed fixtures. Check the Compact Fluorescent Light Bulb's packaging for any restrictions on use.

How to Choose the Right Light:

• Matching the right Compact Fluorescent Light Bulb to the right kind of fixture helps ensure that it will perform properly and last a long time. Read the packaging to be sure that the type you choose works for the fixture you have in mind. For example:
  • If a light fixture is connected to a dimmer or 3-way switch, select Compact Fluorescent Light Bulbs that are labeled for this use
  • For recessed fixtures, it is better to use a 'reflector' Compact Fluorescent Light Bulb versus a standard-shaped bulb.
• Choose the color that works best for you. For example, while most Compact Fluorescent Light Bulbs are created with warm colors for your home, you could choose a cooler color for task lighting.
• To get a Compact Fluorescent Light Bulb with the right amount of light, choose one that offers the same lumen rating as the light you are replacing. The higher the lumen rating, the greater the light output. Use the table below to see how lumens can generally be compared. Keep in mind, though, that the lumens put out by Compact Fluorescent bulbs varies greatly by make and model, so always read the packaging carefully before purchasing.
