ENERGY STAR is a government-backed program
that helps consumers identify the most energy-
efficient products.
This document is designed to help you promote ENERGY STAR qualified
light bulbs.
• Section I includes the latest consumer messaging on productfeatures
and benefits, as well as fun facts and usage tips.
• Section II summarizes the most recent data on ENERGY STAR market
share, ENERGY STAR criteria, energy savings, and cost-effectiveness.
ADVANCED TECHNOLOGY
ENERGY STAR qualified light bulbs use innovative technology to produce light in a
very efficient way. Electricity creates a chemical reaction among gases located
inside the glass tube, causing special phosphors to illuminate. This means ENERGY
STAR qualified light bulbs are at least three times more efficient than regular bulbs.
DID YOU KNOW?
Incandescent light bulbs were invented by
Thomas Edison in 1879, and the basic design
has not changed much since. These bulbs
are very inefficient, converting only 10% of
the electricity consumed into visible light.
The remaining 90% of the electricity is
actually released as heat!1
Take a look! ENERGY STAR qualified light bulbs use sophisticated electronic circuitry to
generate light. All you have to do is change the bulb. ENERGY STAR makes it simple.

Though incandescent light bulbs seem cheaper at the
store, they'll actually hit your wallet harder in the long run.
ENJOY ENERGY SAVINGS AND MORE!
The average U.S. household has more than 40 sockets for light bulbs, ranging from
table lamps to ceiling fixtures. Larger homes can have even more. Lighting accounts
for about 20% of annual household electricity bills, or approximately $200 per year.2
Replacing incandescent bulbs with ENERGY STAR qualified light bulbs provides
significant benefits for consumers:
• SAVE TIME AND EFFORT
ENERGY STAR qualified light bulbs can last more than seven years, compared
to about 11 months for an incandescent bulb—that's eight times longer!3
• SAVE ENERGY AND MONEY
Over its lifetime, one ENERGY STAR qualified light bulb eliminates the need for
eight incandescent bulbs and saves you more than $30. By changing five bulbs
to ENERGY STAR, you save more than $150!4
• STAY COOL
Because ENERGY STAR qualified light bulbs run cooler, they make your home
more comfortable. They are also safer to use in light fixtures that have delicate
paper or fabric shades.
• SAVE THE ENVIRONMENT
When you choose an ENERGY STAR qualified light bulb, you are making a
difference for the environment by reducing air pollution and greenhouse
gas emissions.

DID YOU KNOW?
ENERGY STAR qualified light bulbs run cool and
will last longest when used in fixtures that have
plenty of airflow.
WHERE TO USE
LET IT SHINE. ENERGY STAR qualified light bulbs provide the greatest savings
in fixtures that are on at least two hours per day. Put them where you leave the
lights on the most in the evening, such as the family/living room, kitchen, dining
room, and porch.
LET IT FLOW. ENERGY STAR qualified light bulbs perform best in open fixtures
that allow airflow, such as table and floor lamps, wall sconces, pendants, and open
ceiling fixtures.
I'M SPECIAL. If a light fixture is connected to a dimmer or three-way switch, you'll
need to use a special ENERGY STAR qualified light bulb designed to work in these
applications. Check the packaging for more information.

WHAT IS A
LUMEN ANYWAY?
A lumen is actually the measurement
of light output. Unlike watts, which
measure the power consumed by the
bulb, lumens indicate the amount of
light you are getting.
ENERGY SAVING
LIGHT BULBS
HOW MUCH LIGHT?
To choose the ENERGY STAR qualified light bulb with the right amount of light, find
a bulb 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."
You can also check the lumen rating to find the right bulb. The higher the lumen rating,
the greater the light output.
To determine which ENERGY STAR qualified light bulbs will provide the same amount
of light as your current incandescent bulbs, consult the following chart:

WHAT IS A
KELVIN ANYWAY?
The color of light is often described
using a term called color temperature,
which is measured in degrees Kelvin
or kelvin (K). Lower Kelvin numbers
mean the light has a warmer color, while
higher Kelvin numbers mean the light
has a cooler color.

ESTIMATED NATIONAL
MARKET SHARE
FOR ENERGY EFFICIENT
LIGHT BULBS12
DRIVING CONSUMER DEMAND
National market share of ENERGY STAR qualified light bulbs remains relatively
small - less than five percent of total light bulb sales in 2005.n Tremendous
opportunities exist to increase consumer awareness and transform the light
bulb market.
Increasing the sales of ENERGY STAR qualified light bulbs will require effective
consumer education. Educating consumers is a multi-step process, generally
categorized into the following stages:
1. AWARENESS: Consumers discover ENERGY STAR qualified light bulbs as an
alternative to incandescent bulbs.
2. BENEFITS: Consumers understand why ENERGY STAR qualified light bulbs
are better for them.
3. WHERE TO USE: Consumers learn that ENERGY STAR qualified light bulbs
work best in fixtures that allow airflow and are on for at least two hours.
4. HOWTO CHOOSE: Consumers know which bulbs to purchase for their lamps
and fixtures.
ENERGY STAR MARKET SHARE
The U.S. Department of Energy is attempting to collect comprehensive market
information about ENERGY STAR qualified light bulbs. In the meantime, limited
market information is available through research done by energy efficiency
program sponsors (EEPS). One notable study, prepared by Itron, Inc. as part of a
multi-year program evaluation effort for Southern California Edison, has attempted
to estimate market share on a national level. Though the data set does not contain
sales information from all types of retailers, the report provides some indication of
relative changes in market share since 1999. (See chart below.)
It is important to note that ENERGY STAR qualified light bulbs last about eight times
longerthan incandescent bulbs and thus lead to reduced sales of incandescent
bulbs in future years. As a result, the full impact of past ENERGY STAR qualified
light bulb sales will continue to be seen in market share figures for future years.

REGIONAL ACTIVITIES LEAD TO REGIONAL SPIKES
SHARE—SOME SUCCESSES
MARKET
During the west coast energy crisis of 2000-2001, high utility prices and threats
of blackouts motivated consumers to pay more attention to their energy
consumption. Many Californians responded by purchasing energy efficient light
bulbs. As a result of this surge in consumer interest, market share in California
rose from one percent of unit sales to more than eight percent within six months.13
In the Pacific Northwest, regional sales increased more than eightfold between
the end of 2000 and 2001, when program sponsors offered instant rebates and
increased promotional activities in response to the west coast energy crisis.14
In 2002, Wisconsin Focus on Energy offered instant rebates in 375 retail outlets
throughout the state and offered mail-in rebates statewide. Market share in
Wisconsin increased from three percent to eleven percent.15
Beginning in 2002, New England states re-focused their promotional efforts
on a buy-down program with manufacturers to reduce prices at the wholesale
level. In Massachusetts alone, sales increased from less than 500,000 in 2002 to
more than 3 million in 2004.16

ENERGY STAR CRITERIA
The efficiency of light bulbs is measured by efficacy—the comparison of light output
to power consumption—and is expressed in lumens per watt (Im/W). To earn the
ENERGY STAR, light bulbs must provide at least three times more lumens per watt
than standard incandescent bulbs. See the table below for the specific efficacy criteria.
In addition, ENERGY STAR qualified light bulbs must meet a number of other criteria to
ensure quality. The criteria include:
• A minimum rated lifetime of at least 6,000 hours (many qualified bulbs exceed this
level significantly—products range from 6,000 to 15,000 hours with an average
of 8,000 hours)17
• A minimum 2-year manufacturer warranty for residential applications and a
minimum 1-year warranty for commercial applications
• Start time of less than one second
• Warm-up or "run up" time of less than 3 minutes
• Color rendering index (CRI) of 80 or higher18
COST EFFECTIVENESS
1. Average rated life of all ENERGY STAR qualified light bulbs = 8,000 hours
2. Average lifetime if used 3 hours per day: 7.3 years19
3. ENERGY STAR price premium = about $5.00
4. Time to recover initial investment = less than 1 year
5. ENERGY STAR qualified light bulb price range = $1.00 to $20.0020
