Compact Fluorescent Light Bulbs for Consumers

If every American home replaced just one light bulb with an ENERGY STAR qualified bulb, we would save enough energy to light more than 3 million homes for a year, more than $600 million in annual energy costs, and prevent greenhouse gases equivalent to the emissions of more than 800,000 cars.

ENERGY STAR qualified CFLs

• ENERGY STAR qualified bulbs use about 75 percent less energy than standard incandescent bulbs and last up to 10 times longer.
• Save about $30 or more in electricity costs over each bulb’s lifetime.
• Produce about 75 percent less heat, so they’re safer to operate and can cut energy costs associated with home cooling.
• Are available in different sizes and shapes to fit in almost any fixture, for indoors and outdoors.

How to Choose and Where to Use CFLs

ENERGY STAR qualified CFLs provide the greatest savings in fixtures that are on for a substantial amount of time each day. At a minimum, ENERGY STAR recommends installing qualified CFLs in fixtures that are used at least 15 minutes at a time or several hours per day. The best fixtures to use qualified CFLs in are usually found in the following areas of your home:

• family and living rooms
• kitchen
• dining room
• bedrooms
• outdoors
