LED BULBS: A FRIENDLY LIGHTING SOLUTION

August 29th, 2010

Out of all the many ways on saving the Earth from further destruction is by eliminating some known ways such as banning the use of incandescent lamps and possibly CFLs. In the near future, production, distribution and utilization of incandescent bulbs will be a crime. This is due to the many environmental issues disclosed as the damage of the technology accumulated for years since its creation.

Incandescent bulb is an invention particularly made by Thomas Edison and has been a long time lighting solution of the world. Not only thus it has made the Earth brighter it has also made the Earth cry due to the pollutions actively occurring with it. What are those pollutions? Incandescent bulbs carry with it light and thermal pollution. Incandescent bulbs produce light that is not focused. It diffuses on all possible ways, therefore some of the lights that were not utilized on the area intended to be lit can be assumed of as pollution. On the other hand, thermal pollution happens because this kind of lamp emits light with high temperature. The heat it emits will just add up to the factors aggravating global warming.

In the year 2012, the US government will be starting to ban the utilization of incandescent lamps and expected the total extinction by the year 2014. This was devised to be followed by all the states. A number of countries have also did their part by also banning its use such as, the Philippines, Europe, Brazil, Canada, Australia, Malaysia and a lot more. Though purchasing incandescent lamp is cheaper as compared to the suggested alternatives, the dark side of it is just reasonable enough to make it on a halt.

Now that the extinction of incandescent bulb is near, several substitutes were already out for public’s judgement such as CFLs, HIDs and LED Lighting.

Focusing on the now famous LED bulbs, it can guarantee efficiency as an exchange for its price. One can consider acquiring LED Lights as an investment because it will definitely pay-off after several years of usage, and one will likely to be amazed on the amazing return of investment. Now more and more are shifting to the LED technology as the answer to every lighting problem. It does extend its life ranging from 10-13 years without decreasing its feature abruptly. Moreover, energy saving due to the efficient use of energy particularly in producing light (not heat) is also one of the main features that are typically designed to entice clients of different walks of life. It also does not introduce light and thermal pollution because it produces focused light and emits minimal heat. Many manufacturers and producers are making its way into making this technology affordable to all.

Certainly, LED bulbs are the now assumed most friendly lighting solution, not just to the consumers but also to the natural environment. Thus, making use of this lighting technology is highly commended not just for specific lighting solution, but for every possible lighting need.

GO GREEN

August 20th, 2010

In an effort to sustaining life on Earth despite depleting natural energy sources, more and more individuals are engaging their time into finding ways on how to turn the usual home into a green home. In a world that is entirely run and dominated by things that are electrically powered, one should take into consideration that in one way or another, time will come that the world will suffer from energy sources shortage and that time is starting now. Alternative energy sources are highly commended such as energy from the sun, wind, water, etc.

These alternative energy sources are classified as green technology that focuses on energy. Why is it called green? It is called as such because it focuses on providing technology on diverse field that promotes eco-friendly solutions by employing stuff that are not a threat to the environment. Furthermore, this technology offers long service life and can guarantee the same function as the existing technology it replaces. However, employing this may cost a fortune, but for sure the benefits and the performance guarantees to cover the acquisition price taken for a long time.

An example of green technology is the wind power technology. In essence, wind, like light, is a form of solar energy that is caused by the unevenness of the temperature in the atmosphere caused by the sun, rotation of the earth and the irregularities of the surface of the earth. Wind is also used as a means to producing electricity. How? Wind energy is used to move the wind turbines that then convert kinetic energy into mechanical energy or electricity; the exact opposite of the principle in electric fan which uses electricity to produce wind. So in places where the wind power is high enough to rotate the turbines, wind power technology is the best alternative for coal and fuel burning.

In light of this, since saving energy is the main issue employing efficient energy appliances or gadgets is also commended. Stuffs that can foster this feature are also considered eco-friendly because it reduces the need to produce electricity thus saving energy sources. An almost perfect example of energy efficient appliances is the LED lights. Why? LED lights are known to consume only a fraction of power that other conventional lighting requires. The process of producing light by the light emitting diode and the choice of materials use to construct them eliminates the emission of high temperature, therefore eliminating the possible wasting of energy that may just end up as thermal pollution. Moreover, employing this kind of lighting solution will not only give the consumer energy efficient lighting system but also superior lighting features that is un-compromised. It gives the equivalent brightness and luminance that its conventional counterpart can give with a more or less 70% energy savings. This is definitely a great performance combined in one lighting solution.

Now that more and more are shifting to go green, time will eventually come that the world will be full of concerned individuals that opts to make life on earth safe and sound just like before.

WORLD LIGHTING SOLUTION: LED LIGHTS

August 16th, 2010

After several years since the creation of the world, we are now facing the accumulated damages brought about by a lot of advancement made by humans. Different strategies and methods are now being formulated and devised by a lot of concerned individuals that will promote the decrease in the amount of damages accumulated per year. Among the solutions that are now taking in the lime light is the banning and phasing-out of some dangerous human creation like the incandescent bulbs and compact fluorescent lamps.

Incandescent lamps have been such a wonderful creation of Thomas Alva Edison. It has served almost all the people around the globe. It has been the answer to a lot of lighting problems. It is very cheap and readily available. But now that the energy resources all around the world is depleting, the cost of maintaining incandescent lamps is expensive. It produces light and at the same time heat so it consumes a lot of electrical energy for it to work. Another kind of incandescent lamps that is also being banned is the halogen lamp. Halogen lamps are made of tungsten, inert gas and halogen. Tungsten acts as the thin filament and requires to be heated at a temperature equal or less than 3,422°C or 6,192°F. Imagine the amount of electrical energy required to heat that tungsten filament! It is reported and decided that within the years 2012 and 2014, incandescent lamps will be banned in the United States. Some countries including Brazil have already banned the use of it. Although some are against it, the environmental benefits of banning it are further being explained to them.

Counties should consider banning CFL bulbs. Although, as been proven CFLs are much energy efficient and longer service life than the incandescent lamp, CFL’s contain materials that can harm the environment if not properly disposed. CFLs contain mercury that is used to excite the electrons to produce the necessary illumination. It costs twice as the incandescent lamp because it includes the disposal fee at the end of its life. By now, a lot of waste management are not accepting its disposal because of the mercury threat on the land and to the people exposed to them.

A lot of viable options are being exposed to the public. One of the safest and inexpensive means of operating is the LED bulb.

LED lights can be purchased on a much higher cost than the other two lighting means, but because of its many practical benefits, it justifies the cost. An LED lamp can last up to 13 years and consumes only a fraction of energy as what the other two consumes. Moreover, it doesn’t need to be maintained at a regular phase. It is fitting flawlessly on the sockets of the conventional lights. Above it all, it emits almost no heat, therefore doesn’t add up to the factors that contribute to the global warming, and it is not composed of environmentally hazardous substances that are known to damage the earth.

Proper knowledge and exposure to the most viable alternatives to the lighting solution of the world is the key to getting the best out of it.

AFTER INCANDESCENT LAMPS AND CFLs, WHAT’S NEXT?

August 16th, 2010

With the advent of high technology advancements, the environment is being compromised in the sake of better and more advanced lifestyle on Earth. Now that a majority of natural energy sources, what can we do to prolong the support for human existence? There are different measures that have been submitted for evaluation including all possible means of having alternative energy sources and banning of some stuff that could make the depletion rate faster and introduces threat to the environment and to human race. Among the candidates for being obsolete are the incandescent bulbs and compact fluorescent lamps (CFLs). Why? Because of some reasons related to the damaging natural environment.

It was agreed upon by the government of the United States of America that within the years 2012 and 2014, the use of incandescent bulbs will be banned. This is because it consumes a lot of energy to produce light, thing that will definitely add up to the increased depletion rate of the natural energy sources. It is requiring an enormous amount of electrical energy to produce light. Its brightness entirely depends on the wattage that is applied to it. Although it is a very cheap substitute for the natural light and is readily available in the market, the operational cost is high as compared to other lighting system. Many are opposing to the scheduled eradication of this long time lighting solution because of its cheap price, but the government is educating the people on the practicality on facing back to this kind of lighting system.
On the other hand, as a measure of saving the earth from being too exposed to different poisonous substances, compact fluorescent lamps or CFLs are now scheduled to be phased-out in the coming 2015 in the United States. This act is in accordance with the natural environmental issues pertaining to the construction and disposal of the CFLs. Although it is more energy efficient than the incandescent lamps and lasts for a longer service time, it threatens the environment through disposing with it its mercury content. Mercury or hydrargyrum is a known substance coming from cinnabar or mercuric sulfide. It is a highly toxic chemical that can be obtained through inhaling or ingestion of the dust. Once CFLs are disposed, the mercury it contains will mix with the soil and makes it reddish in color. A lot of land fills are now prohibiting the disposal of mercury in the area. Users of CFLs are advised to recycle or just keep the busted CFLs for future processes.

One of the candidates to replace the two is the LED lamps, which are widely known to last for a longer period of time, with no additional cost for its maintenance and most of all consumes only a fraction of energy as what the other two requires. It is safer to use because it doesn’t contain harmful chemical compounds just to produce light and emits heat very minimally. More and more are now utilizing LED lighting as a substitute for the conventional lighting system and experience its practical advantages that are known to answer the energy and environmental issues of the other two conventional lighting systems. It is likely that in the years to come, a lot of users had already switched to LED lights, providing light to every possible corners of the earth.

HAZARDS OF CFL’s DUE TO MERCURY: WHEN WILL IT END?

August 16th, 2010

Compact fluorescent lamps (CFLs) are good substitute to the now being banned incandescent lamps. It is more energy efficient and lasts longer than its counterpart. CFLs are more expensive because the price includes the disposal fee. It was introduced in North America in mid 1990s. Although it is more energy efficient than the incandescent lamps, its composition makes its disposal complicated. CFLs are known to contain mercury which is a very serious threat to the environment once disposed improperly. Mercury functions as the vapor inside the glass tubing of CFLs. Usually CFLs contains around 3-5 mg of Mercury; some have it as low as 1 mg. In essence, Mercury is utilized as vapor in a phosphor tube, which when electricity pass through, it produces short-wave UV (ultraviolet light) which causes the phosphor to fluoresce, therefore making visible light.

Mercury or Hydrargyrum or quicksilver is a liquid metal with a symbol Hg. Mercury is a poisonous chemical that can be derived from major deposits as cinnabar or mercuric sulfide, the reason for vermilion, the red pigment responsible for the reddening of the soil. The poisonous substance can be ingested or inhaled mercury vapor or by eating mercury contaminated fish. Mercury poisoning which is also known as mercurialism or hydrargyria is the disease that can be derived from exposure to mercury or its components. Acrodynia, Hunter Russell syndrome and Minamata disease are among the list of those mercury related diseases. It affects body senses such as impaired vision, hearing and speech. Disturbed sensation and lack of body coordination are also among the symptoms.

Imagine the world full of mercury-filled CFLs, time will come that the number one cause of human fatality is mercury poisoning. Steps are being taken into account for the eradication of CFLs. By the year 2015, the government of the United States of America will implement the banning of use of CFLs to stop the possible exposure to mercury. Although it is expected that many users of CFL will stop this banning procedure, a lot of informative measures are being given to the public to further understand why the government is pursuing this act.

When this thing comes into action and given that the incandescent bulbs will as well be phased-out, what can substitute CFLs as lighting solution? Majority are thinking that LED lamps are the next thing to be on the spot light to cater all the lighting requirement of the world.

LED lamps can be considered a viable means as alternative to the prevailing lighting system which are expected to be obsolete in the years to come. LED lamps are a lot more beneficial to employ than those two. Imagine the comfort one can have if for a long time, around 10 – 13 years, he will not be thinking of replacing bulbs and maintaining it. Additionally, LED lamps are comparatively using very low energy and still can give-out the equivalent brightness and luminance compared to its counterpart. Considering the price of purchasing LEDs, one just have to consider LED lighting as an investment that will definitely pay-off in the years to come.

Ample information should have to be distributed to further inform the public regarding the practical benefits of choosing LED bulbs over the other lighting options available today.

PAR 30 LED Lights

August 16th, 2010

Among the list of the modern application of LED technology is in making the use of incandescent bulbs obsolete. A revolutionary way of implementing LED technology in replacing incandescent light bulbs is on PAR lighting. Here, the bulbs are enclosed in a parabolic aluminized reflector to further enhance the lighting effect. It produces an intense pool of light, usually oval in shape, with unfocused edges.

One of the many variations of LED PAR lights is the par 30 led lights. It has a nominal lamp bell diameter of 3.75 inches or 95mm. The nominal diameter can be computed by dividing the PAR size by 8 (in inches). So in par 30 led lights, 30 divided by 8 gives a diameter equal to 3.75 inches. It is composed of a number of LED lights connected together to act as one. It gives-off light that has the same brightness as what the halogen par lamps can give.

Application of par 30 led lights has been found in a variety of theatrical or live musical shows. It also functions to making ice sculpture alive by providing aesthetic lighting effects. In a lot of exhibits, mural walls, staircases or corners that needs for an emphasis, led par lights can be of excellent choice. Moreover, it gives-off a light that is not disturbing to the eyes of the viewer. It doesn’t produce glare so it is not an annoying thing to the eyes.

Although purchasing any LED lighting solution is expensive at first cost, it is justified by the fact that the possibility of not changing lights within the next 10 or more years. LED exhibits long life that can last to more than 50,000 hours. It can easily be mounted and is compatible with the existing light bulb socket. It doesn’t flicker, has low maintenance, highly reliable, very efficient and most of all enables the user enormous power saving. It dissipates low heat therefore doesn’t add up to global warming and is considered friendly to the environment. It has also deemed its significance and ability to replace halogen lamps and gradually make it obsolete.

Prevailing lighting system such as incandescent and fluorescent bulbs has short life-cycles and uses excessive carbon emissions to produce its power requirements. It is also utilizing mercury used to provide lights. Because of the hazardous requirement of the prevailing lighting system, it is likely to pollute the environment.
Some models of par 30 led lights are at the 7.0 watt range and likely to give-off a 50W equivalent of the incandescent bulbs with 420 Lumen output. Some outputs an equivalent light of 60W and 650 Lumens. Some specifications are different for some models.

With the aim of reducing electric bill, employing LED lighting system will surely to give you satisfaction. Due to the fact that it uses LED lights which consumes small amount of electrical energy and emits low temperature, it certainly follows that the energy or power consumption is lower as compared to its equivalent halogen or incandescent lamp. Aside from promoting low electric bill, it doesn’t compromise the quality of light it produces.

Ways to Reduce Your Electricity Bill

August 10th, 2010

Now that the whole world is experiencing from high priced services, one has to be clever enough to save money and still maximize the service. Not only thus it enables financial saving for the consumer, it also entails a move into saving the natural environment due to lesser coal burning. There are so many practical ways that is applicable to a lot of discipline. Some of the ways are:

1. The most practical and basic cost-reduction scheme that has been proven very effective is by turning-off unnecessary appliances when not in use. This is especially true for appliances with motors such as electric fans, television sets, etc., and those that emit heat, like flat iron, microwave oven, heaters, lights, etc. This type of appliances employs the function of transformers that introduces inductance and most likely to produce wasted energy because of the added consumption in the transformer.

2. Instead of just turning off electronic devices, it is more advised to unplug it. Electronic devices are still consuming energy even if it is turned-off because it still has standby current, that even though negligible at first time, it can be accumulated and can still add-up to the total energy consumption and bill.

3. Schedule activities that are done in a weekly basis such as washing and ironing clothes. Washing the clothes at the same time will not only enable power saving, but also water and effort savings.

4. Arrange things in the refrigerator to enable proper air circulation around the refrigerator. Avoid unnecessary opening in the fridge door. Moreover, to check for the food cooking in the oven, turn-on the lights instead of opening the oven door.

5. To better facilitate indoor lighting, allow for the natural light from the sun to penetrate the house by opening the windows. It doesn’t only allow light to come-in but also the air, so it can eliminate the use of lights and electric fans or air conditioner during day time.

6. Use appliances that are designed to save energy like refrigerators that offers high efficiency which in turn does not waste energy. Air conditioners, on the other hand can be replaced by electric fans. Incandescent bulbs can be replaced by CFL that exhibits longer life than the latter. Moreover, it also enables greater energy saving than the incandescent bulb.

7. Employ new technologies that offer great energy savings like LED technology. LEDs are designed to replace incandescent bulbs, CFLs and other conventional lighting system. LED technology offers quality lighting while enables power saving because it utilizes lesser power and emits negligible amount of heat. It also lasts for an extended period of time even if used 24/7. It doesn’t only enable great energy saving but also no hazard on disposing, and therefore, environmentally friendly unlike the CFLs that contains mercury.

There are still a lot more practical ways on reducing power bill, one just have to be dedicated and consistent of exercising those basic but proven practical ways. Recording previous bills can be used to keep track on the development and savings made.

LED Return of Investment Calculator

August 4th, 2010

Due to the widespread application of LED technology in a lot of lighting discipline, many clients are satisfied by what that technology gives them. As known information, purchasing the LED lighting system will cost much as compared to the traditional lighting systems being implemented, but that is only at the first cost. Employing the system will definitely mean an investment. Because of adopting all the benefits and advantages of employing LED bulbs, the investment can be returned not in terms of money, but in terms of financial savings. The rate of return of investing in the LED can be computed by using the LED ROI calculator. This calculator determines the yearly power and energy cost savings and possible lifetime saving once you decided to replace those conventional lighting system to LED.
Now to compute the ROI of LED, first one must determine the following important details regarding the bulb to be replaced and the LED.

1. Original Bulb wattage
2. LED replacement bulb wattage
3. Number of bulbs to be replaced
4. Number of Hours of use per day
5. Number of possible days to use
6. Number of possible weeks to use
7. Energy cost per kWh
8. LED replacement bulb life (in hours)
9. Cost of LED replacement bulb (each)
10. Original bulb life (in hours)
11. Possible labor cost in changing original bulb (maintenance)
12. Cost of original bulb
13. Cost to install replacement LED light

Those are the needed information in computing the following:
1. Total kilowatts saved
2. Total kilowatt saved per year
3. Total energy cost saving per year
4. Lifetime energy cost savings
5. Total lifetime bulb changing cost savings (maintenance)
6. Total amortized replacement cost savings per year

Mathematically, this works by the following formula:
1. To compute for the Total Kilowatts Saved:
D = {(a-b)*c}/1000
Where: D= total Kilowatts saved (kW)
a = original bulb wattage (W)
b = LED replacement bulb wattage (W)
c = # of bulbs to be replaced

2. To compute for the Total kilo watt hour saved per year:
H = D*e*f*g
Where: H= Total kWh saved per year (kWh/yr)
D = total kilowatts saved
e = total number of hours use per day (hr/day)
f = total number of days per week (day/week)
g = total number of weeks per year (weeks/year); 52 weeks max per year

3. To compute for the total energy cost savings per year:
J = H*i
Where: J = total energy cost savings per year ($)
H = total kWh saved per year (kWh/yr)
i = energy cost per kWh ($)

4. To compute for the lifetime energy cost savings:
M = (k/l)*J
Where: M = Lifetime Energy Cost Savings
k = LED Replacement bulb life (hrs)
l = total number of hours used per year (hr/yr)
J = total energy cost savings per year ($)
*** To compute the simple payback on energy consumption:
O = (n*c)/J
Where: O = Simple payback on energy consumption (yr)
n = price of each LED replacement bulb
c = # of bulbs to be replaced
J = total energy cost savings per year ($)
***To compute for the ROI
P = 100 / O
Where: P = ROI (%)
O = Simple payback on energy consumption (yr)

5. To compute for the cost savings from upgrading to LED; Total lifetime changing cost savings
Q = {(k/r)*(s+t)*c}-u
Where: Q = total lifetime changing cost savings ($)
k = LED Replacement bulb life (hrs)
r = original bulb life (hrs)
s = labor cost in changing the original bulbs
t = cost of original bulb
c = # of bulbs to be replaced
u = cost to install LED replacement

6. To compute the total amortized replacement cost savings per year:
V = Q/w
Where: V = Total amortized replacement cost savings per year ($)
Q = total lifetime changing cost savings ($)
w = (k/l) (yr)
*** To compute the simple payback on energy consumption plus replacement costs:
X = n/V
Where: X = simple payback on energy consumption plus replacement costs (yr)
n = price of each LED replacement bulb ($)
V = Total amortized replacement cost savings per year ($/yr)

*** To compute the ROI:
Y = 100/X
Where: Y = ROI (%)
X = simple payback on energy consumption plus replacement costs (yr)

Those are the things that can be computed by the LED ROI calculator given all the necessary details in replacing the traditional bulbs by LED lights.

LED Lights for Businesses

July 26th, 2010

M. J. reports that “I installed LED lights in my retail store. We experienced an immediate fall in the energy bills. We also found that customers were attracted by the better ambiance of the store front, visibility of merchandise and some just came to see the LED light in operation as they wanted to experience it before buying it.”

This is not an account of a progressive cash rich transnational corporation and M.J. is not a business manager in a modern retail store. M.J. is a small kiosk owner in Africa. The story above is one of the many such accounts summarized in Research Note Number 2 of the Lumina project that evaluated the impact of LED devices on business prosperity in remote Kenya. Whether in Africa or America, the reasons for the popularity of LED bulbs are similar.

Globally LED lighting technology is changing the way business is conducted. The aforementioned study, funded by the US DOE (http://light.lbl.gov/pubs/rn/lumina-rn2.pdf) demonstrated that businesses that adopted off grid LED lights in Kenya experienced substantial gains. In the process this study of the impact of this big daddy of energy efficient lights proved a few things.

1) Businessmen even in remote Kenya understood the meaning of life cycle costs. They bought the lights at unsubsidized rates and refused to sell them back at the purchase price after six months!

2) Those who invested in this cutting edge lighting technology were unaffected by the shortage of fossil fuel for lighting needs.

3) The gains were not limited to lower energy bills. Better light quality resulted in better visibility of goods and sales. Customers were attracted to these ‘early adopters’ shops to experience the superior lighting technology at work. This resulted in higher footfalls and sales.

4) Safety was an important reason for buyers in Kenya.
The story from elsewhere in the developing world are similar. Thrive foundation has helped illuminate several remote villages in India, Africa and Afghanistan resulting in longer productive hours and improved living standards.

Closer home in United States and Canada businesses have been switching to LED lighting technology in a big way. The financial storm propelled the demand for LED lights as businesses realized the importance of reducing operational expenses. Starbucks was one of the first global corporations to switch to this energy efficient lighting technology. Several universities and even cash strapped municipalities have followed suit.

Par Lights are a Popular Lighting Choice

July 21st, 2010

DOE estimates of U.S. Lighting Market Characterization suggest that there are close to 350 million incandescent recessed lights in operation of which 76% are in the residential sector. Different types of bulbs can be used in recessed lights. Here is a description of some of the most common types of bulbs to help you make an informed choice.

Type of Lamp Image of Lamp Life Efficay (Lumens per Watt) Description
Reflector Lamp (R-lamp) 2000 Hours 9 Lumens/ watt This kind of lamp throws light in one direction only. It is coated with a reflective material and is filled with an inert gas like argon. A number of R lamps have been phased out as they have poor luminous efficiency.
Parabolic Aluminized Reflector Lamp (PAR-lamp) 2000-3000 Hours 12.5 Lumens/ watt The reflector is Parabolic and projects a tighter beam of light than R lamps.PAR lamps are better for use in recessed fixtures as they throw a larger percentage of the light out of the fixture. Advanced PAR lamps use a reflector layer to retain heat and achieve a higher filament temperature and efficiency.
General Lighting Service GLS lamp (A-type) 750 Hours 15.8 Lumens/ watt The A type lamp is one its way out due to strengthening regulations on luminous efficiency. Though it is not a reflector lamp it is used in reflector lamp fixtures particularly in a residential setting.
LED PAR Light 30,000-50,000 Hours 100 Lumens/ watt This kind of lamp throws light in one direction only. It is coated with a reflective material and is filled with an inert gas like argon. A number of R lamps have been phased out as they have poor luminous efficiency.

A few simple calculations demonstrate the impact that PAR lights can bring about. The table below shows a base case scenario if incandescent PAR lights are replaced with Energy efficient LEDs.

Variable Residential Sector Commercial sector Total
Average daily operating hours 2.3 10
Annual kWh/lamp 61 266
Peak coincidence factor (% on at peak) 7 75
Average operating cost 0.1 0.1
Installed base (Millions) 265 85 350
With traditional Halogen Lamps
Lamp wattage (Average) 73 73
Annual kWh (millions) 16240 22648 38888
Peak demand (MW) 1354 4653 6007
Annual operating cost ($ Million) 1624 2264 3888
With energy efficient LED Par lights
Lamp wattage (Average) 12 12
Annual kWh (Millions) 2669 3723 6392
Peak demand (MW) 222 765 987
Annual operating cost ($ Million) 266 372 639
 
Savings ($ million) in operating costs from LED PAR lights 1357 1892 3249
Reduction in peak demand (MW) 1131.55 3888.75 5020.3

All the data used in the analysis above is in the public domain and anyone can draw up his own spread sheet. The figures may vary a bit but the conclusion will always be the same. Reducing energy consumption is the prudent choice. An annual saving of $ 3249 million is no small figure. Neither is the projected reduction in peak electricity demand. Installation costs of each additional KW of fresh electricity generating capacity range between $ 2700 to 6000 per KW. Given that peak electricity demand can be reduced by 5020 MW the savings in installation costs alone would be of the order of 15000 to 25000 million dollars. The high cost of adding new generation capacity is the reason why many utilities encourage customers to reduce their energy consumption by giving rebates and educating them about energy efficiency. Energy efficient products have another advantage. They help bring productive, high value jobs back to United States. These are some of the reasons why MyLEDLightingGuide is committed to a greener future
