The Advantages of LED Lights
Long-lasting - LED bulbs last up to 10 times as long
as compact fluorescents, and far longer than typical
incandescents.
The operational life of current white LED lamps is
50,000 hours. This is 11 years if used during all
Night. The long operational life of an led lamp is a Durable - since LEDs do not have a filament, they
are not damaged under circumstances when a
stark contrast to the average life of an
regular incandescent bulb would be broken.

virtually eliminate the need for routine bulb
replacement.
Cool - these bulbs do not cause heat build-up;
There is no comparison between the cost of LED
lights vs. traditional Halogens. With Halogens
bulbs, the true cost of the bulb is the cost of
replacement, labour expense and time needed to
replace them. These are significant factors,
especially where there are a large number of
installed bulbs. For office buildings and
skyscrapers, maintenance costs to replace bulbs
can be enormous. These issues can all be
virtually eliminated with the LED option.
LEDs produce 3.4 btu's/hour, compared to 85 for
incandescent bulbs. Common incandescent bulbs
get hot and contribute to heat build-up in a room.
LEDs prevent this heat build-up, thereby helping to
reduce air conditioning costs in the home.
Mercury-free - no mercury is used in the
manufacturing of LEDs.
More efficient - LED light bulbs use only 2-17 watts
of electricity (1/3rd to 1/30th of Incandescent or
CFL). LED bulbs used in fixtures inside the home
save electricity, remain cool and save money on
replacement costs since LED bulbs last so long.
power Small LED flashlight bulbs will extend battery life 10
to 15 times longer than with incandescent bulbs.
The key strength of LED lighting is reduced
consumption. Halogen bulbs which operate at
about 20% efficiency (80% of the electrical
energy is lost as heat). In real money terms, if a
100 Watt incandescent bulb is used for 1 year,
with an electrical cost of 10 cents/kilowatt hour,
$88 will be spent on electricity costs. Of the $88
expense, $70 will have been used to heat the
room, not light the room. If an 80% efficient LED
system had been used, the electricity cost would
be $23 per year - there would be a cost savings
of $65 on electricity during the year. Realistically
the cost savings would be higher as most
incandescent light bulbs blow out within a year
and require replacements whereas LED light
bulbs can be used easily for a decade without
burning out.
Cost-effective - although LEDs are initially
expensive, the cost is recouped over time and in
battery savings. LED bulb use was first adopted
commercially, where maintenance and replacement
costs are expensive. Today, there are many new
LED light bulbs for use in the home, and the cost is
becoming less of an issue. To see a cost
comparison between the different types of energysaving light bulbs, see our Light Bulb Comparison
Charts.
Light for remote areas and portable generators because of the low power requirement for LEDs,
using solar panels becomes more practical and
less expensive than running an electric line or
using a generator for lighting in remote or off-grid
areas. LED light bulbs are also ideal for use with
small portable generators which homeowners use
for backup power in emergencies.

ADVANTAGES OF LED LIGHTING
LE D lig htin g s av e s el ect r ic it y.
The lighting efficiency of the new high power led light bulbs is more than eight times that of incandescent lights, and twice as high
as compact fluorescent lights. Led bulbs also emit a much higher percentage of light in the desired direction. This makes them even
more efficient compared to either incandescent or fluorescent for task lighting, desk lamps, reading lights, spotlights, flood lights,
and track lighting.
Led lights also generate very little unwanted heat. The energy savings may be doubled in air-conditioned environments where each
watt of incandescent lighting can add another watt or more to the power needed for air conditioning.
Fluorescent lights are dim when first turned on, and get brighter as they warm up. Depending on the temperature and the age of the
lamp, they can take a long time to warm up. If it is cold enough they will not warm up at all. Led lights always start at full brightness.
Fluorescent lights contain mercury and must be treated as hazardous waste. (View EPA guidelines for fluorescent bulbs). Led
lighting contains no mercury or other dangerous substances.
As the program makes clear, "low voltage" halogen lights are not low energy consumers. The standard halogen downlight uses 50
watts. The transformer in the ceiling uses a further 10-12 watts. The more modern electronic transformers use less - perhaps 3-4
watts - but that's still extra power consumption on top of the 50W bulb. So every downlight (and many people have eight or ten in a
room) is using the same amount of energy as a 60 watt incandescent globe. Ten or 20 years ago the same space would probably
have been lit by a couple of 60 watts bulbs, or a fluoro strip using a fraction of the energy.
L e d l i g h t i n g d o e s n o t p r o d u c e a n y u l t r a vi o l e t ( U V ) l i g h t .
Led lights emit no damaging ultraviolet light, so they will not cause fading and aging of artwork or other sensitive materials.
Fluorescent and halogen lights can cause significant damage over time.
Led lighting saves on bulb replacement.
Led bulbs can operate for 30,000 hours or more. One led lightbulb can easily outlast 30 incandescent bulbs, or 6 compact
fluorescents! Led bulbs cost less than the bulbs they replace. Operating 8 hours per day, led light bulbs can last 10 years or more!
Led light bulbs are less sensitive to shock, vibration, and the extreme temperature changes that can quickly ruin fragile
incandescent bulbs. And unlike fluorescent bulbs which wear out much faster if they are frequently turned on and off, led bulbs are
not affected by frequent on-off switching.
The long life of led light bulbs reduce the time, effort and cost of replacement.
Led lighting increases safety and security.
The high reliability of led lights increases safety and security. There is no waiting for led light bulbs to warm up. Led bulbs light up
instantly at full brightness, even in the coldest weather.
The other major problem with any downlights, and halogens in particular, is the effect they have on insulation. It's illegal to lay batts
over the top of any downlight, so there will be a gap in the insulation wherever one is installed. This reduces the effectiveness of
ceiling insulation quite dramatically. Because halogens (unlike UCFLs and LEDs, see below) give off so much heat, they are more
dangerous - although most insulation is fire-resistant or inflammable, there have been housefires caused by insulation catching fire
from halogens. Indeed, the Melbourne Fire Brigade recently stated that there had been an average of 30 house fires each year in
Melbourne caused by halogens. It's very important to leave at least 150mm of space between a halogen downlight and any
insulation material. You can buy special protectors to put around the downlight in the ceiling. Insulation can be packed right up to
the protector. But they're not cheap (around $15 each).
Led lights are safer.
Led bulbs operate at much lower temperatures. Halogen and incandescent lights are hot enough to cause fire, and they frequently
do.

FAQ
Frequently Asked Questions about LED Lights
Answer: a light emitting diode (LED) is a semiconductor device that emits visible light when electrical current passes
through it, it is a special kind of diode.
Answer: most LEDs are monochromatic. Light color is associated with the light wavelength. LEDs made with different
semiconductor materials emit lights in different wavelengths. LED light wavelengths range from 400 nanometers
(blue) to 800 nanometers (red). The colors of popularly available LEDs in the market are white, warm white, red,
orange, yellow, green and blue .
Answer: yes and no. LEDs have increasingly been used in many different applications to replace old incandescent
light bulbs. Examples include LED indicator lights for all kinds of electronic devices such as cell phone, calculators,
automotive dash panel, LCD back-lighting, etc., LED seasonal decoration lights for Christmas and holidays, LED traffic
signs and other LED direction signs, LED flashing lights, and so on. Currently LEDs are limited brightness, but this is
increasing as better technologies are developed to make it brighter.
Answer: there are several obvious advantages LEDs have over traditional incandescent light bulbs:
Low power consumption - energy saving.
Long lasting.
Cold lighting.
Ruggedness.
Small size.
Fast switch times.
Simple to use.
Yes. Currently available LEDs are more energy efficient than incandescent bulbs, but less than florescent bulbs with
the same light output. The power consumption of popular LEDs ranges from 30mW to 200 mW.
People can save money & energy by using LEDs instead of equivalent incandescent decorative bulbs.
The rated average working life of LED is 50,000 - 100,000 hours compared with 1,000 hours of incandescent bulbs.
LEDs emit cold lights as working LEDs generate very small amount of heat, so LEDs are much safer than equivalent
incandescent light bulbs in terms of danger of fire. LEDs don’t have filaments to heat up in order to emit lights just
like the case of incandescent bulbs. Lights are emitted from LEDs as a result of energy exchange occurring in the
different semiconductor materials an LED is made of.
LEDs are usually shielded with solid transparent plastic materials so they are more rugged than incandescent and
florescent bulbs that are usually sealed with glass.
The second significant disadvantage is the high prices of LEDs. The currently available LEDs in the market are 3 ~ 10
times more expensive than equivalent incandescent light bulbs. This is why some customers still hesitate to buy LED
products even though LEDs have so many obvious advantages over incandescent bulbs and people actually can save
money by using LED products in the long run.
Answer: the most popular LED products available in volume at the market place are various kinds of LED decoration
light products. And in fact, they are ideal for replacing conventional incandescent decoration light products, because
when compared with incandescent light products, these LED products save up to 95% energy, have much longer
working hours, are more rugged, and safer in terms of danger of fire and electric shock.
At present, people can buy beautiful LED light strings, LED rope lights, LED icicle strings, and individual round LED
bulbs with changeable colors, LED rope lights, LED pipe lights, and more other LED products will be put into market
in the near future.
Answer: LEDs are more reliable. Most available LED light strings have series configuration like old incandescent light
strings, where lights in the string are connected in series with each other, so a disconnection of LED light from the
string will always make the entire string fail just like incandescent light strings. However, in the case of light burning,
an incandescent light bulb will always burn open, namely, the filament of the incandescent bulb breaks, so the whole
string will always fail, while an LED light may either burn open like an incandescent light bulb or burn short where a
short circuit is formed inside the LED, so the burned LED will stop lighting but all the rest LEDs in the string still light
normally. And LEDs usually burn short, therefore, LEDs are more reliable than incandescent light bulbs in that
respect.
Answer: yes, there is. Various LED string products are more reliable than those LED strings in series connection in
market. OUR strings use a unique patented connection configuration that ensures an LED string will work normally
even one or several LEDs are disconnected from the string while keeping the low prices and all the features of LED
strings.
Answer: the reason is that different semiconductor materials are used for different color LEDs, and some
semiconductor materials are more expensive than others; another reason is that manufacturing costs are different.
White LEDs are the most expensive because red, green and blue LEDs are combined together to make a white LED.
Lighting can contribute to over 30% of a households total electricity bill. By replacing inefficient halogen and
incandescent light globes with energy efficient and cost effective LED lights, you will reduce your electricity bill and
your carbon footprint.
LED comparison to Halogen and Compact Fluorescents (CFL) proves why LED is the clear winner.
Incandescent and Halogen Lights
Incandescent lights are the most commonly used form of lighting. This includes the standard everyday light bulbs
and halogen downlights. On the offset, they are inexpensive to buy but their lifetime running costs quickly add up.
An incandescent light creates light by running electricity through a filament, which heats up and then literally glows
white-hot. It is a very inefficient way of creating light as 90% of the electricity used is turned into heat with only 10%
being turned into light.
Incandescent lights are very dangerous and are a fire hazard with halogen lights being responsible for many
household fires. The filaments in halogen lights rise up to 2,500°C and the bulb up to 500°C. The temperature at
which paper will ignite without a spark or flame is 230°C, so if there is any insulation touching the light fitting a fire
can easily start.
Because incandescent emit so much heat, your cooling system needs to work harder to compensate amounting to
extra costs in energy bills. The lamp life of an incandescent is only an average of 1,000 hours making regular
replacement necessary which wastes money on maintenance costs. It is also very impractical in hard to reach places
such as high ceilings.
Compact Fluorescent Lights – CFL – Energy Savers
Compact fluorescents have come a long way from the flickering, unflattering light they once were. They are now
available in a wide range of light temperatures, are longer lasting than incandescent lights and are more energy
efficient. CFL's have a lamp life of about 10,000 hours and use approximately 80% less energy than an equivalent
incandescent.
CLF's use gas, mercury particles and phosphor to create light. The gas becomes excited by electricity, and when
combined with mercury particles, produces invisible ultraviolet light. The UV light then hits the white phosphor
coating inside the bulb causing it to fluoresce and emit white light. There is circuitry inside the base of the light that
stops it from flickering like in old flourescent lights.
Most CFL's have a charge up time usually using about 5 times the bulbs wattage rate for roughly 10 minutes, making
them inefficient for areas where fast switching is needed and where lights are frequently switched on and off. They
also take around 30-45 seconds to reach full light output from a cold start.
The main issue with CFL's is the large amount of energy and materials that go into manufacturing them. Fluorescent
tubes can contain up to 15mg of mercury that is an extremely toxic element, especially dangerous to pregnant
women, babies and children. One fluorescent tube contains enough mercury to pollute 30,000 litres of water. It is
essential that all CFL's and Fluorescent tubes are recycled appropriately.
