PARTNER RESOURCE GUIDE

SECTION 1: CONSUMER INFORMATION

This document is designed to help partners understand and promote L E D
lighting products that meet the ENERGY STAR criteria established by the
U.S. Department of Energy (D O E). You are free to use any of its
messaging and graphics to promote ENERGY STAR qualified products on Web
sites, print advertisements, in-store promotional materials, and other
marketing materials. This document is dividedinto two sections:

Section 1 includes consumer messaging on product features and
benefits,as well as fun facts. Section II summarizes the market outlook
for ENERGY STAR L E D products.

ADVANCED TECHNOLOGY

ENERGY STAR qualified L E D lighting products are integrated systems
with the light source built into the fixture. Qualified lighting
products contain a number of high-powered L E Ds arranged inside a
fixture to efficiently produce high-quality white light.

ENERGY STAR is a government-backed program that helps consumers identify
the most energy efficient products.

This page contains an image of an L E D desk lamp where you can see two
lines of six L E D's inside the head of the fixture.

What are L E D's?L E D stands for light-emitting diode. L E D's are
small light sources that become illuminated by the movement of electrons
through a semiconductor material.

L E D's are part of a family of lighting technologies called solid-state
lighting (S S L).This family also includes O L E D's (organic light
emitting diodes). O L E D's (pronounced oh L E D's) consist of sheets of
carbon-based compounds that glow when a current is applied through
transparent electrodes. While not yet market ready, O L E D's are likea
thin film on a wall or ceiling that illuminates a room. Like L E D's, O
L E D technologyis advancing rapidly.

DID YOU KNOW?

In the next 20 years, L E D lighting inthe United States could (footnote

Reduce electricity demandsfrom lighting by 33 percentby 2027.

Eliminate 570 million metrictons of carbon emissions

Avoid 40 new power plants.

Save as much as \$265 billion in energy costs.

LESS HEAT, MORE LIGHT

This table illustrates the major differences between incandescent light
bulbs, Compact Fluorescent light bulbs, and L E D devices.

The first image is an illustration of an incandescent light bulb with a
red glow around it and an outline around the red glow is labeled "heat",
outside the circle of red glow is a circle of yellow outlined with the
word "light". The illustration shows that incandescent light bulbs give
off a lot of heat along with the light they produce.

The second image is of a compact fluorescent light bulb (CFL) with a
small orange circle around the glass portion of the bulb outlined as
"heat" and a larger yellow circle outlined as "light" to show that the
CFL produces less heat compared to the incandescent.

The last image in this table is of an L E D device. The illustration of
the L E D device shows a yellow beam of light coming from the top of the
device labeled "light" and orange arrows coming out the bottom of the L
E D device labeled "heat" to show that L E Ds emit directional light and
the heat is handled in the back end of the device leaving L E Ds
basically cool to the touch.

Basic Parts of L E D Lighting

L E D lighting starts with a tiny chip (most commonly about one square
millimeter) comprised of layers of semi-conducting material. The chip or
chips are mounted on heat-conducting material called a heat sink and
usually enclosed in a lens. The resulting device, typically around 7 to
9 millimeters on a side, can be used separately or in arrays. L E D
devices are mounted on a circuit board, which can be programmed to
include lighting controls such as dimming and time sensing. The circuit
board is mounted on another heat sink to manage the heat from all the L
E D's in the array. The system is then encased in a lighting fixture,
architectural structure, or even a "light bulb" package.

THE VALUE OF D O E ENERGY STAR QUALIFIED L E D LIGHTING

With the rapid advancement of L E D technology, it's important to
remember that not all L E D lighting products are created equal. The
ENERGY STAR label gives consumers confidence that an L E D product meets
strict efficiency and performance criteria established by D O E. These
products are designed to perform as well as or better than traditional
lighting in terms of brightness, light quality, and energy efficiency.
They also come with a minimum three-year manufacturer warranty.

WHAT'S INSIDE?

This table provides an illustration of the basic parts of an L E D
lighting system. First an L E D Device, then a circuit board, then an
array of L E D's, then a heat sink, and then an L E D package.

LOW-POWERED L E D's & HIGH-POWERED L E D's

This table provides a side by side comparison of the two main types of L
E D devices. Low-powered L E D's have a more simplistic design, while
high-powered L E D's are much more complex.

SAVE ENERGY

ENERGY STAR qualified L E D lighting uses at least 75 percent less
energythan incandescent lighting. ENERGY STAR qualified L E D lighting
is at least as efficient asfluorescent lighting.

SAVE TIME

The image is of a woman on a ladder changing a light bulb in a recessed
can in the ceiling.

Stop changing light bulbs! Qualified L E D lighting products integrate
thelight source and the fixture, meaning you'll never have to change a
bulb.

ENERGY STAR qualified L E D lighting for homes lasts at least 25
timeslonger than incandescent lighting, and 2.5 times longer than
typical fluorescent lighting (footnote 2). Products made for the
commercial sector last at least 35 times longer than incandescent
lighting, and at least 3.5 times longer than typical fluorescent
lighting (footnote 3).

LIGHT BEAUTIFULLY

ENERGY STAR qualified L E D lighting provides a clear and consistent
shade of white light throughout the lifetime of the fixture. Superior
light quality won't harm art, fabric, or other materials.

ENJOY BETTER DESIGN AND PERFORMANCE

Superior directionality allows for precision lighting. Compact,
low-profile fixtures offer greater flexibility in placement. Durability
ensures consistent performance and rare breakage. Performance is
enhanced in cold temperatures, making qualified L E D's perfect for
outdoor use. L E D's turn on instantly; there is no warm-up time.

Dimming, timing, and color controls allow for reliable custom
settingswhen used with compatible controls. L E D's produce far less
heat than incandescents. This reduces airconditioning needs.

TABLE: ANNUAL OPERATING COST COMPARISON FOR RECESSED DOWN LIGHTING

This table compares three different light sources used in recessed down
lights, their light output measured in lumens, the wattage, the
lifetime, and the annual operating costs. The first column lists the
light sources, "the Incandescent bulb" has 575 lumens of useful light
and 575 lumens of wasted light, uses 75 watts, lasts 1,000 hours and has
an annual operating cost of \$8.87. The Compact Fluorescent light bulb
(CFL) has the same amount of useful and wasted light as the incandescent
bulb but uses 20 watts, lasts 10,000 hours, and has an annual operating
cost of \$2.37. The ENERGY STAR qualified LED recessed down lighting has
575 or the same amount of useful light as the other two light sources
but has no wasted light, uses 16.5 watts, has a lifetime of at least
25,000 hours, and an annual operating cost of \$1.95. Annual operating
costs are based on an assumed use of three hours per day and an average
utility rate of 10.8 cents per kilowatt hour.

GRAPH: LIFETIME COMPARISON OF LIGHT SOURCES

This graph illustrates the lifetime of three light sources. The graph is
split into two parts, Residential lighting on the left and Commercial
Lighting on the right. The Residential lighting portion shows a stack of
25 incandescent light bulbs next to a stack of 2.5 CFLs next to a single
L E D. The Commercial portion of the graph shows 35 incandescent light
bulbs next to 3.5 CFLs next to a single LED.

ADDING UP ENERGY EFFICIENCY

When designed to be used in homes, ENERGY STAR qualified L E D light
fixtures last for at least 22 years without ever needing a bulb change!
You would need 25 incandescents or 2.5 CFL's to last that long (footnote
5).

In commercial uses, ENERGY STAR qualified L E D light fixtures can last
for more than 10 years without ever needing a bulb change! Over that
time, you would use 35 incandescent bulbs or 3.5 pin-base CFL's
(footnote 6).

ENERGY STAR QUALIFIED L E D LIGHTING PRODUCT TYPES

L E D technology is best suited to certain types of lighting
applications where the performance of the L E D product equals or
exceeds that of existing lighting options.

The D O E ENERGY STAR criteria cover requirements for L E D products
usedfor general illumination, including those with a significant
decorative function.The criteria apply to both residential and
commercial products.

Currently, D O E ENERGY STAR qualified L E D lighting covers fixtures,
but not L E D bulbs designed to replace regular screw-base incandescent
bulbs. L E D bulbs will be included in the program when their
performance meets that of current light bulbs. D O E will expand the
ENERGY STAR program to include other lighting applications as L E D
technology improves.

Aren't all L E D lights highly efficient and long-lasting?

Unfortunately, no. While L E D lighting technology is unsurpassed in its
efficiency,

using L E D's to create stable white light for general lighting presents
new challenges. Some manufacturers claim greater efficiency and
durability than their products deliver. To be assured that L E D
products perform as well as the packaging claims, choose an ENERGY STAR
qualified model. The market share of L E D's for general lighting is
relatively small, but it has expanded significantly in recent years and
is expected to grow exponentially as the technology continues to
improve. The figure below demonstrates the development of the L E D
lighting market and the increasing size of the illumination market for L
E D's.

TYPES OF ENERGY STAR QUALIFIED L E D LIGHTING

This table shows the seven types of lighting that are currently covered
in the ENERGY STAR program for LED lighting and lists some unique
benefits next to a photograph of each lighting application. All seven
applications are residential while five of the seven are also available
for commercial lighting.

The D O E ENERGY STAR L E D lighting program includes the residential
and commercial products shown above. All qualify for residential use,
while those with an asterisk (\*) also qualify for commercial use.

DRIVING CONSUMER DEMAND

Increasing sales of ENERGY STAR qualified L E D lighting requires
effective consumer

education to build confidence in the technology. Educating consumers is
a multi-step

process, including; AWARENESS: Consumers discover ENERGY STAR qualified
L E D lighting as an alternative to traditional residential and
commercial lighting.

KNOWLEDGE: Consumers learn how ENERGY STAR qualified L E D lighting may
benefit them. ACTION: Consumers begin to rely on the ENERGY STAR label
to find quality products. D O E recommends that partners use plain
language in marketing materials to introduce ENERGY STAR qualified L E D
lighting to consumers. Messaging should build on consumers' existing
knowledge of lighting products to ease the learning curve. In
particular, partners should avoid jargon that is specific to the
industry.

Image of a kitchen with recessed down lights. The U.S. Department of
Energy estimates that at least 500 million recessed down lights

are installed in U.S. homes and more than 20 million more are sold each
year. L E D technology can decrease recessed down light energy use by 75
percent or more.

Chart of L E D Lighting Terminology

Left column title is: Use Regularly. Terms used regularly are L E D
Fixture, Brightness or light output, Efficiency, Color or light color or
shade of white light, Color accuracy or true color. Right column title
is: LIMIT USE / AVOID. Terms to limit use or avoid are S S L, Luminaire,
Lumens or luminous flux, Luminaire efficacy, Correlated color
temperature (CCT), Color rendering index (CRI).

DRIVING DEMAND IN THE COMMERCIAL SECTOR

In the early stages of market development, the low operating costs of
ENERGY STAR

qualified L E D lighting products may be most appealing to commercial
consumers.

Commercial consumers are likely to have greater awareness of advanced
lighting

technologies and have more lighting technology alternatives at their
disposal.

Commercial consumers may therefore be drawn to more detail L E D
information that

will increase their knowledge of the benefits of L E D lighting and the
value of the

ENERGY STAR label, such as the potential to earn points for LEED
certification.

SECTION II : MARKET OUTLOOK

The market share of L E D's for general lighting is relatively small,
but it has expanded

significantly in recent years and is expected to grow exponentially as
the technology

continues to improve. The figure below demonstrates the development of
the L E D

lighting market and the increasing size of the illumination market for L
E D's.

In 2007 alone, the global market for general L E D lighting grew by
approximately

\$125 million. Strategies Unlimited forecasts that the total market for
L E D's will grow

at an annual rate of 37 percent, reaching about \$1 billion by
2011(footnote 9).

D O E predicts that the area of greatest potential growth, particularly
in the

introductory stages of L E D lighting, lies with commercial consumers.
One

company forecasts that L E D's will produce at least 75 percent of
commercial

lighting in the United States by 2030 (footnote 10).

Graph of AWARENESS OF L E D's. This line graph shows the increase of
articles published about L E D's in newspapers from 2004 to 2007. In
2004 there were a little over 200 articles about L E D's, in 2006 there
were 345 articles, and in 2007 there were 534 articles that mentioned L
E D's.

Graph of Recent Market History. This bar graph shows the market size of
a variety of applications of LED lighting in millions of dollars from
2001 to 2007. The bar graph shows a steady increase over the years
beginning with 1,200 million dollars in 2001 to 3,600 million in 2004 to
4,600 million in 2007. Between 2001 and 2004 the market increased at a
rate of 44% per year, and from 2004 to 2007 the rate slowed to 7.6% a
year. The applications for L E D's included were mobile appliances,
signs/displays, automotive, signals, illumination and other (footnote
11).

D O E ENERGY STAR L E D LIGHTING CRITERIA

D O E has made a long-term commitment to the development and market
introduction of solid-state lighting (SSL), which includes L E D
lighting. D O E recognizes the need for a coordinated approach that
guides technology advances from the laboratory to the marketplace. D O
E's ENERGY STAR L E D lighting criteria address product quality and
efficiency, helping ensure that residential and commercial consumers
have a positive experience with this new technology. The criteria
consider four features of L E D lighting: Luminaire efficacy. (The
efficiency of the light that leaves the fixture).

Minimum light levels that match existing technology. Limited correlated
color temperature. Industry-accepted test procedures. To ensure product
quality, the criteria will only apply to the most market-ready
applications. In 2011, D O E will expand the ENERGY STAR program to
include a wider variety of L E D applications for general lighting. D O
E's ENERGY STAR criteria require L E D products to deliver at least 70
percent of initial light output for the minimum number of hours
specified below:

Residential indoor: 25,000 hours. Residential outdoor: 35,000 hours. All
commercial: 35,000 hours. The lifetime requirement for residential
indoor products is lower because of the shorter operating cycles typical
of residential indoor applications. For example,

residential indoor lights are on an average of three hours per day, but
commercial

lighting products are generally used at least ten hours a day. Please
