How to Choose and Where to Use CFLs
How to Choose the Right Light
More than 20% of the electricity generated in the U.S. is used for lighting. Approximately
half of this energy is wasted by lighting empty rooms or as heat produced by inefficient
lamps. But it's easy to save money and energy with ENERGY STAR® qualified
light bulbs and fixtures. 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.
The
new generation of ENERGY STAR® qualified compact fluorescent light bulbs (CFLs) :
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
diverse, versatile and elegant, with an energy efficient solution for almost every
lighting fixture type and any design need.

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, and outdoors . |
How to Choose the Right Light:
Matching the right CFL
to the right kind of fixture helps ensure that it will perform properly and last a long
time.
CFLs perform best in
open fixtures that allow airflow, such as table and floor lamps, wall sconces, pendants,
and outdoor fixtures.
For recessed
fixtures, it is better to use a reflector CFL than a spiral CFL since the design of the
reflector evenly distributes the light down to your task area.
If a light fixture is
connected to a dimmer or three-way switch, you'll need to use a special ENERGY STAR®
qualified CFL designed to work in these applications. Make sure to look for CFLs that
specify use with dimmers or three-way fixtures.
Choose a qualified
CFL that offers a shade of white light that works best for you. For example, while most
CFLs provide warm or soft white light for your home, you could choose a cooler color for
task lighting.
To choose the ENERGY
STAR® qualified CFL with the right amount of light, find a qualified CFL that
is labeled as equivalent to the incandescent bulb you are replacing. Light bulb
manufacturers include this information right on the product packaging to make it easy for
consumers to choose the equivalent bulb. Common terms include "Soft White 60" or
"60 Watt Replacement."
