The Using Of LED Flood Lights
This short post is going to explore LED Flood Lights.
If you are trying to find one of the most popular type of flood lights in the industry today then you should be impressed at the up-to-date lighting development which has been obtaining remarkable feedbacks from consumers; it is generally known as LED lights. LED which is short for light emitting diode has been widely used in many devices mainly as indicating lighting.
LED flood lights have completely revolutionised outdoor lighting and have made LED the perfect lighting solution for any sort of outdoor weather condition. LED flood lights are more economical than a normal floodlight for the reason that it can save you energy up to 80% compared to a standard incandescent light. The life span of an LED lamp is evaluated to be 100,000 hours long and LEDs used in lighting can last up to 30,000 to 50,000 hours; you'd be burning out 2 or 3 or even more fluorescent lights just before an LED flood light will begin to flicker.Since an LED flood light will likely be utilized in the outdoors, it's fully maintenance free of charge. It is always prepared to make use of given that it powers on with just a press of a switch in comparison to some outdoor lighting that flickers before powering on. With an LED flood light, you will hardly ever need to sacrifice with lighting conditions, it may be as bright as a regular incandescent or halogen bulb but with less energy consumed.
An LED flood light is an excellent investment seeing that it will make available to you years of usage unlike normal lighting that will flicker and fail following a year. Even on a foggy day, you would be able to be sure that an LED flood light will light up your garden without fail, it may also do the job in snow or sleet weather conditions.
When browsing on the internet, you may be able to obtain the best value in LED flood lights. You will probably find web sites that are committed to introducing this modern lighting technologies to regular purchasers. You could be able to view an extensive gallery of LED lights and also flood lights and also read extensive info on how LEDs can do magic for your dwelling and enterprise.
The most typical LED flood light could be the 100W assortment which is available in white, red, blue and green colors and RGB. You may be able to even get much more savings if you purchase by bulk for your dwelling or your business. With LED lights, you can efficiently illuminate any area for just a tiny proportion of the energy charges of a standard light bulb.
Other floodlight types are the 20W, 40W, 30W 50W ,60W and etc option. You could be able to pick the ideal flood light depending on the size of your garden or the location that wants to be lit.
LED lights has been creating superb reviews with regards to energy efficiency. Absolutely conventional lighting are not able to comparable to the power and lighting flexibility of an LED light. A growing number of house owners are using LEDs as their indoor and outdoor lighting source and it is likely that more and more people will do the exact same in the near future.

The Utilizing of Flexible LED Strip Lights
The Utilizing of Flexible LED Strip Lights
This content will talk about the points that need to be taken care of when adopting of flexible LED ribbons.Nowadays, flexible LED strips have been broadly utilized in many lighting applications especially in decorating lighting and have been proved to be a very sufficient decorative lighting solution. Yet, still, many consumers are not educated about this new product and have not much concept of how to use it. For that reason, in this piece of content we are going to talk about the points that need to be attended to when utilizing of flexible LED strip lights.
In the following paragraphs, issues like the current, the voltage, the power consumption, the length and the controller etc would be covered.
The constant current of LED tapes is typically to be 20mA, for this reason the current supplied by the power is not allowed to be higher than 20mA. Some people would pay attention to the input voltage of the power supply but seldom take notice of the working current. But bear in mind,it will lead to the risk of burning of the LEDs when the working current is higher than the LED's rated current.
The typical programs of SMD LED strip lights is for decoration lighting. Usually, the installation jobs will be carried out by the enginerring or installation compaines. However, due to the lack of complete understanding of SMD LED strip lights, a lot of consumers would miss some facts when calculating the cost, due to this fact, it increases the cost of it, some of them are unnecessary costs . Below is an example for demonstrating how to calculate the cost of engineering and installation flexible SMD LED strips.
The length of LED tapes: Normally, the quantity of LEDs per meter of a flexible strip light should be 30, and 60. But, 48, 120 and 240 LEDs/m can also be found. Typically, flexible LED tapes can be cut by every 3 LEDs. For a 60 LEDs/m LED strip, the length of every cuttable group is 50mm; for a 30 LEDs/m ribbon, then the length of every cuttable group would be 10mm. Please note that here we just take the 12V strips for instance, if for a 24V version, the number of LEDs per cuttable group and the length of every cuttable group would be doubled. Based on this knowledge, the quantity of LEDs to be used for a certain project will be calculated practically.
Power supply for flexible LED strip lights: Different types of LED strips have different power consumptions, it is very important to choose the correct power supply for a strip. For instance:
3528 LED tape, 12V, 60 LEDs/m, 4.8W per meter, current: <0.4A per meter
5050 LED tape, 12V, 30 LEDs/m, 7.2W per meter, current: <0.6A per meter
5050 LED tape, 12V, 60 LEDs/m, 14.4W per meter, current: <1.2A per meter
For a 5050 LED ribbon (30 LEDs/m), say the power supply is 12V, 4A (rated power consumption will be: 12 x 4 = 48W), then such a power supply can only drive no greater than 6 meters of 5050 LED strips. Because the power consumption of this strip is 7.2W, therefore the total power consumption for 6m is 43.2W. If the working power consumption is higher than rated power of the power supply, it will reduce the working lifespan of the power supply.Therefore it is recommended that the working power consumption should be under 90% of the rated power consumption.
Controller for flexible LED tapes: RGB (also referred to as 'full colour' or 'colour changing') LED tapes, need a controller to perform its colour changing functionality. Normally, one signle controller can be used to control 5m to 30m of LED ribbons, depending on the rated power of the controller and the working power of the tapes. However, amplifiers can be used with a purpose to extend the length of the RGB strip to be controlled.

Using LED Spot Lamps to Replace Traditional Halogen Spot Lights
Using LED Spot Lamps to Replace Traditional Halogen Spot Lights
The Next Few Paragraphs will cover "Using LED Spot Lamps to Replace Traditional Halogen Spot Lights
Small halogen spot lights are traditionally used to give more focused beam or accent lighting effects. They have been widely used as a more energy-efficient substitute to incandescent lights in retail shops and stores and home lighting systems. The halogen bulbs work at high temperatures, lots of heat dissipated around the ambient lamp. Furthermore, the lamp, especially the filament should not be exposed to severe vibration to keep the lamp from failing too early.For example, the power consuption of the typically used par20 , MR16, GU10 halogen lamps ranges from 20W to 50W, and their lumen output ranges from 160 lm to 700 lm. This means that, it equals to an efficiency of around 16 lm/W. The working life of a traditional halogen lamp is approximately 2000-3000 hours, likely comparable to 3 to 4 months of usage in a shop.
Having read through halegon spot light bulbs, now let's move onto LED spotlamps.
Spot lamps are often utilised as spot or accent lighting in some difficult-to-reach small areas where people would not want the lamps to be changed too frequently. LED lights lasts many times longer than the old-fashioned halogen bulbs. Some LED spot light bulbs are made of a cluster of small LEDs, the other LED spot lights are made up of a smaller quantity of high-power LEDs. Both of them are able to deliver very high-quality light and can be a good retrofit of halogens.Furthermore, LED bulbs need very small proportion of electricity to produce high level of lumens output, quite simply, they get higher effectiveness.As a matter of fact, MR16, GU10 and PAR LED Lights, consume much less power to emit the equivalent amount of light than halogen lamps. Presently, LEDs are able to deliver 110 lm/W in general use (in the lab, this value is much higher), with three 1-watt high-power diode of such, the total light output would be nearly 300 lumens. Besides, with typical focus beam angle of 15, 30 or 45 degree, the lamps can be able to deliver significant amount of usable light without much waste light as halogens do.What's more, the LED technology has been continuously improving from year to year dramatically, higher and higher efficacy diode chips show up in the market.
LED spotlights do not depend on heated filaments or gas materials to provide light, and they do not hold mercury like fluorescents. Because of this , LED lamps can be working very close to delicate items such as jewelry, valuable merchandises in the show case or shelf, expensive ornaments and photos in the house, without heat damage or fading over time.Additionally, LED bulb is the top choice as it is environmentally friendly. It releases much less CO2 emission than incandescents, halogens and fluorescents do, helping to reduce the carbon footprint.
There is another advantage of using LED spot lights as the replacement of halogens. This benefit would be the dimming function of LED lights. Now, the dimmable functionality and be achieved in more and more LED lights. Suppose that, in a cafe or a canteen you run, when some of the tables are not occupied, is it a good suggestion to have the dimmable lights? As you would neither like to waste the electricity nor like to leave the unoccupied tables fully dark?

The Difference of LED Lighting and Incandescents, CFLs
The Difference of LED Lighting and Incandescents, CFLs
This Information will have a discussion about "The Comparing of LED Bulbs and Incandescents, CFLs". As time goes by, it's forecasted that people are not going to see incandescents being used any loner however for the present time, they are still low-cost and conveniently available for purchase hence they can be seen in many buildings. Nevertheless, the more effective alternatives are just going into the market and becoming more cost effective and simpler to purchase thus it is able to be expected to see more and more people making the shift themselves.
You might want to fully discover how come more and more people are selecting LED lighting nowadays, it is good to run a assessment of incandescent, CFLs and LED light bulbs so that it can be comprehended how each of them performs and what the differences are between the 3.
If one is trying to improve in his or her property, even in just one single room, it is still advisable to comprehend as much as possible about how they compare to each other. Usually incandescent lighting are thought to be dinosaurs in the lighting industry. They are the oldest design of lighting available and while still frequently put into use, more and more people are choosing fresher and better light sources.
CFL is short for compact fluorescent lamp. CFLs are another well-accepted alternative that has been making waves in the lighting world. They are steadily driving incandescent light bulbs out of the lighting world. The only part that's really still working for the incandescent is that it stayed the least expensive option when it reaches each type of light bulbs individually.
But bear in mind in the long haul, incandecents are got going to conserve you any power expenditures due to the fact they burn out in a short time and easily, and have to be replaced with greater regularity and still cost more over time to operate so that your utility charges will be higher. A more efficient option is to pay more for the CFLs or LED lights right now and reap the benefits in the long term.
As per price tag from lowest priced to priciest for individual light bulbs mentioned above, then the following would be the order for them (at average prices):
1. Incandescents
2. CFLs
3. LEDs
Bear in mind, LED lights will help you to save the most money eventually with CFLs coming in next and incandescents costing you the most in the long haul than either of the others.
But cost isn't the only contributing factor when shopping for a good light bulb. Features ranks high on the list of principal aspects to check out when shopping for your lighting. Efficiency would be a key element and LED lights beat the game on this scale all round. CFLs is the second best as they perform better and longer than the incandescents.
If the three were put in order from brightest to lightest under equivalent power consumption, it would look like the following:
1. LEDs
2. CFLs
3. Incandescents
E . g ., a 5-6W LED bulb = 10-12W CFL = 40W incandescent light bulb; a 9W LED bulb = 13-15W CFL = 60W incandescent light bulb, in terms of brightness.
Now that you have a solid comparing of incandescents, CFLs and LED lamps, it will help to discover which one may meet up with your specific needs best.

Strong results for Veeco, more MOCVD sales for Aixtron
Veeco continues to see strong orders from China and other regions, while Aixtron has reported more reactor sales in Taiwan.Veeco has reported revenue of $255 million for the quarter ended March 31, 2011, of which Led & Solar revenue was $215 million and Data Storage revenue was $40 million. Revenue was down 15% sequentially, but increased 89% from the same quarter last year. The company's gross margin was 51% and non-GAAP net income was $57 million.
Veeco's bookings for the quarter totaled $231 million, of which $198 million was in LED & Solar. John Peeler, Veeco's CEO, said: "We continued to experience strong demand for MOCVD systems and, while China remained the majority of our bookings, we also received orders from key customers in Taiwan, Korea and the US."
In February 2011, Veeco announced its newest-generation MOCVD system, the TurboDisc MaxBright. Peeler said that Veeco shipped three MaxBright four-chamber systems during the first quarter of 2011.
"Orders have been received from three of the top-tier Taiwanese LED makers, as well as from key customers in Korea and China," said Peeler. "Customers are clearly recognizing that we are helping to enable the industry's transition to Led lighting with a unique value position and the most productive MOCVD systems on the market."
Looking forward, Peeler said that Veeco expects MOCVD order patterns to "remain lumpy from quarter to quarter depending upon the timing of customer deposits. We see order strength continuing in China as it builds its LED infrastructure for solid-state Lighting, and quoting activity in Korea and Taiwan is also picking up with improved utilization rates being reported at key customers."
Further Aixtron systems
In related news, Aixtron SE announced that its latest Close Coupled Showerhead MOCVD platform system, the CRIUS II, has been successfully qualified for mass production by Chi Mei Group.
The 55x2-inch wafer configuration CCS CRIUS II was installed and commissioned by the local Aixtron service team at facilities near the Southern Taiwan Science Park.
Also, Aixtron has received repeat orders from Taiwan-based led chip maker Epistar for multiple AIX G5 HT reactors in a 14x4-inch configuration. The systems are delivered in the first and second quarter of 2011.
Aixtron described the repeat order as "a further endorsement of G5's very rapid time-to-production and excellent system-to-system reproducibility, both of which are key factors in a highly competitive market and a considerable driver of cost reduction."
Ming-Jiunn Jou, president of Epistar, said: "The new reactors will form the backbone of our planned capacity expansion for our high-brightness LED production program. In particular, we have been impressed by the run-to-run and system-to-system reproducibility the G5 has shown. This makes the G5 the leading MOCVD system in terms of throughput and yield, allowing us to quickly ramp up our capacities and expand our product portfolio even further in the direction of solid-state lighting products."

Rensselaer Polytechnic Institute Makes a Breakthrough on Green LED
Rensselaer Polytechnic Institute Makes a Breakthrough on Green LED
It's reported that Researchers from Rensselaer Polytechnic Institute have created a new method for manufacturing green-colored Leds with greatly enhanced light output.Led by led by Christian Wetzel, professor of physics and the Wellfleet Constellation Professor of Future Chips at Rensselaer, the research team etched a nanoscale pattern at the interface between the LED's sapphire base and the layer of GaN that gives the LED its green color.
It has received a good result. The new technique results in green LEDs with significant enhancements in light extraction, internal efficiency, and light output.
According to Wetzel, currently, every computer monitor and television produces its picture by using red, blue, and green. And we already have powerful, inexpensive red and blue LEDs. A similar green LED should lead to a new generation of high-performance, energy-efficient display and illumination devices. This new research finding is an important step in the right direction."

Rensselaer researchers boost green LED efficiency
Rensselaer researchers boost green LED efficiency
Research at Rensselaer Polytechnic Institute leverages a nanoscale pattern to boost the optical efficiency of green Leds in the lab.Green LED efficiency has long lagged behind the capabilities of red and blue devices, but researchers at the Rensselaer Polytechnic Institute (RPI) have reported significant improvements in the lab. The team is forming nanoscale patterns on a sapphire substrate that boosts light extraction, internal efficiency, and light output.
More efficient green LEDs would benefit both solid-state Lighting (SSL) in general-illumination applications and TV and display technology. Equally efficient red, green, and blue (RGB) LEDs could yield white light for illumination and could improve the color gamut in display or TV applications.
Rensselaer researchers boost green LED efficiency
Some early led backlights for TVs utilized RGB LEDs, but the designs generally had to include two green LEDs for every red and blue one - adding significant expense and power consumption to the design. Likewise, RGB LEDs have been used in lighting but the need for extra green LEDs limits the applicability.
Green LED inefficiency stems from a semiconductor physics phenomenon called the charge separation effect. In green LEDs, electrons and electron holes are separated in the quantum-well region of the device. Light is generated when electrons combine with electron holes, but the separation results in fewer such combinations in green LEDs. Researchers have struggled for years with the problem.
Christian Wetzel, Professor of Physics and the Wellfleet Constellation Professor of Future Chips at RPI, is leading the green LED research team. The team etched a nanoscale pattern between the sapphire substrate and the gallium nitride (GaN) material in which the LED is grown.
The team reports a doubling in the internal quantum efficiency of the LED. Moreover, the design enhances light extraction by a factor of 58%. The result could be brighter green LEDs although its unclear how soon the research could be applied in LED production.
"Every computer monitor and television produces its picture by using red, blue, and green. We already have powerful, inexpensive red and blue LEDs. Once we develop a similar green LED, it should lead to a new generation of high-performance, energy-efficient display and illumination devices. This new research finding is an important step in the right direction," said Wetzel. "Green LEDs are proving much more challenging to create than academia and the industry ever imagined."
The research team published the results of its work in a paper entitled "Defect-reduced green GaInN/GaN light-emitting diode on nanopatterned sapphire" that was published in the Virtual Journal of Nanoscale Science & Technology.
Wetzel's team was supported by the US Department of Energy, National Energy Technology Laboratory (NETL) Solid-State Lighting Contract of Directed Research, and the National Science Foundation (NSF) Smart Lighting Engineering Research Center (ERC), which is led by Rensselaer.

The Foley City Council May Made a LED Trial Program
The Foley City Council May Made a LED Trial Program
The Foley City Council is thinking about making a trial program for a system to use Leds to replace florescent and incandescent lights.The council is scheduled to vote this program on May 4. According the official, the system will start by installing the lights in a few locations in city buildings and officials will decide if the savings are worth the costs of converting other structures to the new Lighting. He said an led light will pay for itself in energy savings in about four years.

Sino American to Build Semiconductor and LED Companies
Sino American to Build Semiconductor and LED Companies
Recently, Sino American Silicon Products is reported to divide its semiconductor and Led departments into two independent companies named as "Huanchiu Wafer "and "Sapphire Technology" ,completely owned by the company, which will retain its core photovoltaic business.The base day for the split is set on October 1. And the two new companies will apply for listing their shares on the domestic bourse within one year.Opposite to the trend of merger in the local PV industry, the spin-off will transform the structure of Sino American into a sprawling holding company, consisting of the six major businesses of poly-silicon in the upstream sector, PV crystal and silicon wafer, solar cell, PV module and system, semiconductor, and LED.

Positive Aspects Of Applying LED Tubes Over Other Fluorescent Tubes
This content talks about the positive aspects of employing LED tubes which are energy efficient and environmental protecting.
In these days, in this community of increasing environmental interest, demand for energy-saving bulbs is growing continuously. A lot of people and properties are in the market for lighting options, which could be inexpensive, quite practical and will reduce power utilization. LED tube does seem to be a better solution for the public.
LED is the composition of light-emitting diodes. Actually, these diodes are miniature semiconductors chips, that change electricity into light. The old incandescent lamp provides light as secondary output from intensely heated filament, which necessitates a lot of energy. LEDs conversely convert most energy flowing through them to light that’s why it could be significantly more efficient than the traditional incandescent lights.
The newest technology advances in fluorescent lighting is considered to be compact fluorescent lamps (CFLs). LED Light is however more efficient since it has much longer lifespan (25 times) than that of incandescent bulbs and (8 times) than that of fluorescents.
LED light is presented in different colors which generate a variety of effects in an area. When LED light is going to be chosen, either for workplaces or for residential installation, the level of lighting in that place should be evaluated. This is as a result of a number of levels, which could generate a bright glow or soft feel repeatedly. The reason is that LED light source is originally directional light source. The light output by LEDs is very directional. In another word, its beam angle is usually fairly narrow. Such characteristics could be negative aspect in certain lighting systems, for example, the applications which call for smooth and even lighting distribution. Yet, this downside is not insuperable. Lighting developers usually implement a mist lamp cover rather than a clear cover for the LED tubes, therefore the light output could be very soft and evenly distributed. The price for this solution is some loss on light output – typically, roughly 10% of light output loss. Another use of a diffused lamp cover is to widen the beam angle of the tube, but still, LED tubes could not have a 360-degree beam angle just like the conventional fluorescent tubes do under present technology stage.
LED tubes are generally made of a silicon substrate that houses many LEDs. The substrate is enclosed in a PC pipe (cover) which makes it ready for installation. The LED tubes, unlike the fluorescent tubes, compact fluorescent lamps or energy-saving bulbs, do not contain any toxins or chemicals therefore could be released as common throw away.
One can find main health and environmental hazards, that can be linked with the incandescent and fluorescent lights because of the existence of mercury, that is highly risky and toxic. People who have worked under the enviroement (e . g ., warehouses and offices) where fluorescents are installed, may have a good comprehend of that the flickering lights can cause vision and eye problems, furthermore, some may even cause headaches and dizziness. While LED tubes do not engage such troubles.
Figure out the rewards of applying LED tube lighting for your office or home! You may find it an simple and easy way to enjoy a more comfortable life and at the same time to conserve your power bills.

Benefits of LED Lights Replacement
This article talks about the benefits of LED lights compared with traditional lights such as incandecent and fluorescent lights. The advantages of LED lighting is not only it can save the electricity bills, but also it can save replacement and mantenence cost since it has much longer lifespan.
The foreseeable of home lighting will very soon be the vast distributed adopting and utilize of green energy-saving LED lights. Though the current market for LED lights products is mainly geared towards supporters and the pros, the upsides of LED lighting will raise demand for more cost-effective LED lights. SSL (Solid-State-Lighting) is an interesting field and its been forecasted, that soon, energy-saving LED lighting products are going to be reliable and affordable sufficiently to replace incandescent and fluorecent lights for common use in our homes, in public places, in car parking lots, in street lights, in outdoor signs, in super markets, in shopping malls and offices.
The working lifespan of current LED lamps is 100,000 hours theoretically. This will be more than 10 years of continuing running, or in another caculation, say 33.3% operation (that is 8 hours per day), 34 years of lifespan. The long operational life of an LED light is great advantage compared to an incandescent bulb or a fluorescent tube, which is approximately 4000-6000 hours.
When it comes to cost, it seems a little unfair to LED lights. Most people like to carry out some 1 on 1 comparison between the cost of LED lights and traditional lights such as incandescents, fluorescents and halogen lamps. With incandescent lamps, the true and hidden cost is the electricity bills and the maintenance fee (including the replacement bulbs and the labour fee). When comes to the commercial sector, for example, for shopping malls, car parks, office buildings and highrises, maintenance costs for replacing the light bulbs or light tubes, can be significant. While LED lights here could be a perfect solution.
As soon as developed efficiently, an LED circuit will probably come to 70-80% efficiency, that indicates 70-80% of the energy has been converted to light rather than other forms of energy such as heat. While for incandescent bulbs, only 10- 20% of electricity is used to generate light, at the same time, 80-90% of electric power has been wasted to generate heat. Take a simple example, say if I light up my room with a 100 Watt incandescent bulb (8 hours per day), and the electrical fee is 10cents/kilowatt hour, then for 1 year, my electrical cost for this bulb would be $29 expense, but $23-$26 of this $29 will be spent to heat the room, only $3-$6 is actually devoted to light the room. And if an efficient LED light is used, the energy fee would be only about $9-$11 yearly – 60%-70% saving on electricity each year. Please have in mind that the savings on maintenance and replacements during the next years has not been counted yet.
Although LED lighting hold superb advantages compared to traditional lighting.The critical constraint to the wide adoption of LED lighting is still the present relative high cost of LED lamps as the initial investment. Despite the fact the price is constantly going down, LED lamps are still expensive. Usually, a 3W LED globe bulb, replacement of a 25 watt incandescent, costs around $40. Despite the fact that LEDs are expensive, the initial cost will be paid back in long term, by saving utility and mantenance costs. The best value comes from commercial applications where maintenance and replacement costs are costly.
It is predicted that as the new improvements of LED technologies comming, there will be progressively more LED light adoptions in residential lighting applications. In fact, LED technology has been explored and developed for several decades but only a few years ago, as the white light LEDs were developed, LED lighting began pratical for illumination. And in these short few years, a fast rising industry has being formed. This could also be a proof that LED lighting holds a very promising future. And this future won’t be long.

This will be more than 10 years of continuing running, or in another caculation, say 33.3% operation (that is 8 hours per day), 34 years of lifespan. The long operational life of an LED light is great advantage compared to an incandescent bulb or a fluorescent tube, which is approximately 4000-6000 hours.
When it comes to cost, it seems a little unfair to LED lights. Most people like to carry out some 1 on 1 comparison between the cost of LED lights and traditional lights such as incandescents, fluorescents and halogen lamps. With incandescent lamps, the true and hidden cost is the electricity bills and the maintenance fee (including the replacement bulbs and the labour fee). When comes to the commercial sector, for example, for shopping malls, car parks, office buildings and highrises, maintenance costs for replacing the light bulbs or light tubes, can be significant. While LED lights here could be a perfect solution.
As soon as developed efficiently, an LED circuit will probably come to 70-80% efficiency, that indicates 70-80% of the energy has been converted to light rather than other forms of energy such as heat. While for incandescent bulbs, only 10- 20% of electricity is used to generate light, at the same time, 80-90% of electric power has been wasted to generate heat. Take a simple example, say if I light up my room with a 100 Watt incandescent bulb (8 hours per day), and the electrical fee is 10cents/kilowatt hour, then for 1 year, my electrical cost for this bulb would be $29 expense, but $23-$26 of this $29 will be spent to heat the room, only $3-$6 is actually devoted to light the room. And if an efficient LED light is used, the energy fee would be only about $9-$11 yearly – 60%-70% saving on electricity each year. Please have in mind that the savings on maintenance and replacements during the next years has not been counted yet.
Although LED lighting hold superb advantages compared to traditional lighting.The critical constraint to the wide adoption of LED lighting is still the present relative high cost of LED lamps as the initial investment. Despite the fact the price is constantly going down, LED lamps are still expensive. Usually, a 3W LED globe bulb, replacement of a 25 watt incandescent, costs around $40. Despite the fact that LEDs are expensive, the initial cost will be paid back in long term, by saving utility and mantenance costs. The best value comes from commercial applications where maintenance and replacement costs are costly.
It is predicted that as the new improvements of LED technologies comming, there will be progressively more LED light adoptions in residential lighting applications. In fact, LED technology has been explored and developed for several decades but only a few years ago, as the white light LEDs were developed, LED lighting began pratical for illumination. And in these short few years, a fast rising industry has being formed. This could also be a proof that LED lighting holds a very promising future. And this future won’t be long.

The Benefit of LED Tubes Replacement
Back to 3 or 4 years ago, if someone talked about LED tubes, we may probably have no idea what it is about. But now, when we look around, we could probably see that LED light tubes have become a very hot topic and have been becoming more and more popular year by year or even day by day. The traditional fluorescent lights are widely and typically used in different lighting applications such as industrial lighting, warehouse lighting, commercial lighting, office lighting and residential lighting etc. But nowadays, it seems the moment to consider about replacing them with LED light tubes.
LED or referred to as Light Emitting Diode is environment friendly as they generate light by the movement of electrons in the diode. Comparing with LED, florescent lights waste most of energy to produce heat which are definitely no good to our environment. A typical LED light tube may include hundreds of LEDs. The actual number of LEDs depends on the size of the tube or the illumination requirements.
There area a great deal of positive aspects that drive people to try and make use of tube LEDs. For example:
- Can you imagine how much heat a fluorescent tube light can produce? Have you heard about the complaint made by those people who have to sit or work underneath or near fluorescent tube lights – haven’t mentioned that some of them claimed to suffer from frequent head aches. Not like the conventional fluorescent lights LEDs will not produce much of heat and they would not cause people any head aches. LED lights can be installed wherever you want them to be, living rooms, bedrooms, halls, buses, trains, boats, cabinets, etc. And of course, you may have probably notice there are some Christmas lights and curtain lights that are made of LED lights.
- LED tubes consume 60-70% less energy when in comparison with the fluorescent tubes. Typically, a 20W fluorescent tube can be replaced by a 8-10W LED tube; a 40W fluorescent tube can be replace by a 15-18W LED tube; a 60W fluorescent tube can be replaced by a 24-26W tube LED. And please keep in mind that if taking the ballast and starter into account, the tube LEDs can save even more energy as unlike fluorescent tubes, LED light tubes do not need any ballast and starter.
- LED tubes are available in different sizes and colors (in a more technical way of description, it means color temperature). Currently, LED tubes follow the traditional design of traditional fluorescent tubes (T5, T10, T10, T12 etc). The reason for that is to allow direct replacement of the existing fluorescents without extra retrofit cost by replacing the whole lighting fitting. As a result, the commonly obtainable sizes of LED tubes (take T8 and T10 for example) are 2 feet (600mm), 3 feet (600mm), 4 feet (1200mm) and 5 feet (1500mm) and 8 feet (2400mm). Another advantage it should be looked at is the diverse colors that LED lights can produce. Back in the fluorescent tube ages, the light color of a fluorescent tube can not be chosen. But now, with LED fluorescent tubes, the light color can be cold white, pure white, natural white, warm white, red, green, blue, yellow etc, extremely flexible and user-friendly.
- LEDs have much longer lifespan when compared with other lights. Theoretically LEDs’ lifespan can be as long as 50,000 to 100,000 hours. Of course, when it comes to a lighting fixture, the lifespan is not only about the LEDs, but also related to all other electronic components of the lighting fixture. However, this is the way how LED tubes can help to save your maintenance bills for failed lights replacement.
Despite the fact that there is variety of advantage of LED tube replacement, consumers tend to concern about the downsides. Below would be some of the most concerned drawbacks of LED light tubes:
- One of the major problems (and probably the biggest one) that bother the consumers is its price. LED tube lights are much more costly when in comparison with the fluorescent tubes and incandescent bulbs. The market prices normally vary from $50 to $100. However, considering the LED tubes can work for an prolonged time, the cost is acceptable, especially to those commercial applications that need long-time running.
- Retrofit work could be another issue which is concerned, as you may need to reset the electrical configuration in order to let the tubes work properly. The conventional fluorescent tubes require ballasts and starters which are not needed for the LED tubes. Therefore, ballasts and starters will be removed when installing LED tubes. This means a little extra rewiring work.
To summarize, the pros of utilizing LED tubes are considerably much more when compared with its cons. Its worth to have a try of tube LED replacement.

What Is LED Light
Speaking of LEDs, probably one would have heard and found that everywhere, the computers, the cell phones, the traffic lights, the flat screens and so on. LED’s everywhere in our daily life, providing indications . However, with some exceptions, the initial intention of LEDs was for indication but not illumination, at the very beginning, LED’s had nothing to do with general lighting.
New developments, however, are starting to bring SSL (solid-state lighting) into our homes in the near future. In fact, nowadays, you will find there are many on-line shops that are already selling some LED lights products such as MR16 and GU10 spotlights and LED bulbs.
An LED, originally referred to Light Emitting Diode, is one type of circuit element emitting light when electricity moves through it in the specific direction. Just like a normal diode, electrical current will be blocked when it tried to pass through the opposite direction of the diode. With a positive voltage to the positive siide of an LED, the electrons that must jump down in energy when they cross the diode, in this process, the electron will be emitting the lost energy as light – that is the principle how LEDs emit light. This light is at one specific frequency, and the frequency will depending characteristics of the materials being used. When generating white light that may be applied to illumination , it will need a mixing up of many different clolours – something LEDs did not seemed to be able to accomplish in the past.
Red light was the very first visible light LED to be created, in 1962, followed by yellow and green. Later (actually about 30 years later), in early 1990′s, blue-spectrum LED’s were invented – an enormous advance in usefulness, due to the fact blue light could be joined with red and green to produce white light. Nevertheless, this method was not efficient, and corporations were battling to develop a single diode that is able to generate white light by itself. Then, in 1993, a corporation referred to as Nichia developed the first white LED utilizing a blue LED with a phosphor coating. The coating was the secret to success – it provided sufficient shifting of the light wavelength coming from the diode itself to generate white colored light.
So why, aren’t we using LED lights (in most of our homes) – significantly more efficient than either incandescent or fluorescent lights – to our homes, offices and warehouses? The primary challenge, clearly, is cost. Current white LED’s substrate made up of sapphire additional mirroring layer to reflect light which will otherwise be lost. As a consequence, LED lights that are available on the market cost somewhere around 10, 20 or even more times than traditional lights, too much for the average consumer.
Researchers have realized one way of significantly keeping down the expense of white LEDs by reducing the expensive layer of sapphire. As an alternative solution, they used silicon as the substrate and zirconium nitride as the reflector. This had never been carried out before, primarily because silicon reacts with zirconium nitride and changes its properties. The study solved this by locating a layer of aluminum nitride between the silicon and zirconium nitride.
LED lighting carries various benefits over traditional lighting, most especially in efficiency. LED’s are at the same time more durable than incandescent or compact fluorescent lights, and have the advantage of being without having mercury – a chemical discovered in compact fluorescent lights that makes them difficult to get rid of.
The industry is booming, it is expected that LED lights will be adopted widely in homes and office in the near future (some expect it will be 5-10 years). There are still technologies issues, but the LED industry may finally find its way.
