  • Advantages of LED Lights

    2012-07-12

    The future of household lighting will soon be the wide spread adoption and use of white energy efficient LED light bulbs. Though the present market for finished white LED products is geared mainly towards enthusiasts and early-adopters, the efficiency and cost effectiveness of LED lighting systems will drive demand for more affordable LED lights. Opto-electronics is an exciting area and we predict, that in the near future, white LED lighting applications will be powerful and cheap enough to replace incandescent lighting for everyday use in our homes, in street lights, outdoor signs, and offices.

     Advantages of LED Lights

     

    The operational life of current white LED lamps is 100,000 hours. This is 11 years of continuous operation, or 22 years of 50% operation. The long operational life of an led lamp is a stark contrast to the average life of an incandescent bulb, which is approximately 5000 hours. If the lighting device needs to be embedded into a very inaccessible place, using LEDs would virtually eliminate the need for routine bulb replacement.

    There is no comparison between the cost of LED lights vs. traditional incandescent options. With incandescent bulbs, the true cost of the bulb is the cost of replacement bulbs and the labor 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.

    The key strength of LED lighting is reduced power consumption. When designed properly, an LED circuit will approach 80% efficiency, which means 80% of the electrical energy is converted to light energy. The remaining 20% is lost as heat energy. Compare that with incandescent 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.

    Our white LED lights currently come in packages which contain 36 or 48 LED lamps and can be adapted for use with any power supply or casing. Our clusters allow for conversion to operate from all common caving batteries, e.g. FX5/Kirby pack down to two AA cells, in case portability is needed. We have produced a seven-LED cluster light source as an alternative to low wattage light bulbs and a possible portable light source.

    The main limitation to the adoption of white LED lighting as a lighting standard is the current high cost of led bulbs. Although the cost keeps going down, LED light bulbs are still expensive. A single AC bulb (17 LED), replacing a 25 watt incandescent, will cost about $40. Although LED’s are expensive, the cost is recouped over time and in energy cost savings. Factor in that it is significantly cheaper to maintain led lights, the best value comes from commercial use where maintenance and replacement costs are expensive. Traffic lights and outdoor signs, for example, are being switched over to LED’s in many cities. Smaller arrays, such as those in flashlights, headlamps and small task lights are great for specialty and outdoor use. LED based automotive headlights are current being used in high end luxury cars.

    It will be interesting to see what developments are coming for more residential applications of LED lights. LED lighting technology has been researched and developed for the past two decades and we are beginning to see practical applications from this work. There is already wide spread use of LED traffic signs and LED headlights where a premium is placed on a reliable light source that is cheaper and less labor intensive to maintain. We in the industry are certain that tomorrows LED lights will last longer and consume even less power than todays energy efficient LED light bulbs. LED lighting will be used to replace virtually every type of light, bulb, and lamp that is currently in use.

  • LEDs offer numerous benefits

    2012-07-12

    LED offer numerous benefits due to their mode of operation:

    Energy Efficiency
    LEDs are highly efficient. In traffic signal lights, a strong market for LEDs, a red traffic signal head that contains 196 LEDs draws 10W versus its incandescent counterpart that draws 150W. Various estimates of potential energy savings range from 82% to 93%. With the red signal operating about 50% of the day, the complete traffic signal unit is estimated to save 35-40%. It is estimated that replacing incandescent lamps in all of America’s some 260,000 traffic signals (red, green and yellow) could reduce energy consumption by nearly 2.5 billion kWh. At the end of 1997, more than 150,000 signals were retrofitted, almost all of them red.

    In architectural applications, the greatest penetration of LEDs has been in exit signs, both new signs and retrofits. LED retrofit products, which come in various forms including light bars, panels and screw in LED lamps, typically draw 2-5W per sign, resulting in significant savings versus incandescent lamps with the bonus benefit of much longer life, which in turn reduces maintenance requirements. Some of these products are designed specifically for either on-face or two-face exit signs. Many new LED exit signs are also available, including edge-lit designs. LED products currently make up about 50% of the exit sign market. A study conducted by the Lighting Research Center in 1998 found that about 80% of new exit signs being sold in the U.S. utilize LEDs. Note that most retrofits are restricted to use in stencil-type signs versus panel-type signs.

    Long Life
    Some LEDs are projected to produce a long service life of about 100,000 hours. For this reason LEDs are ideal for hard-to-reach/maintain fixtures such as exit sign lighting and, combined with its durability, pathway lighting. This service life can be affected by the application and environmental factors, including heat and if being overdriven by the power supply.

    Range of Colors
    LEDs are available in a range of colors (see above), including white light. White light can also be produced through color mixing of red, blue and green LEDs. In addition, through the innovative combination of various-colored LEDs, dramatic color-changing effects can be produced from a single fixture through dynamic activation of various sets of LEDs. Manufacturers such as Color Kinetics offer fixtures that employ this principle. Color Kinetics offers track, theatrical, underwater, outdoor and other fixtures utilizing variable-intensity LEDs that can provide more than 16.7 million colors, including white light. These fixtures can be individually controlled via a PC, DMX controller or proprietary controller to generate effects including fixed color, color washing, cross fading, random color changing, strobing and variable strobing.

    Dr. Nadarajah Narendran of the Lighting Research Center is doing some exciting research on the use of colored LEDs in retail display lighting. Preliminary research suggests that using colored LED background lighting combined with spot lighting on merchandise may improve energy efficiency and reduce maintenance costs while catching the eye of the consumer in a fresh manner.

    No UV Emissions/Little Infrared
    LEDs produce no UV radiation and little heat, making them ideal for illuminating objects, such as works of art, that are sensitive to UV light.

    Durable
    LEDs are highly rugged. They feature no filament that can be damaged due to shock and vibrations. They are subject to heat, however, and being overdriven by the power supply.

    Small Size/Design Flexibility
    A single LED is very small and produces little light overall. However, this weakness is actually its strength. LEDs can be combined in any shape to produce desired lumen packages as the design goals and economics permit. In addition, LEDs can be considered miniature light fixtures; distribution of light can be controlled by the LEDs’ epoxy lens, simplifying the construction of architectural fixtures designed to utilize LEDs. A controller can be connected to an LED fixture to selectively dim individual LEDs, resulting in the dynamic control of distribution, light output and color. Finally, DC power enables the unit to be easily adaptable to different power supplies.

    Other Benefits
    The other benefits of LEDs include:

    • Lights instantly
    • Can be easily dimmed
    • Silent operation
    • Low-voltage power supply (increased safety)

  • China LED lighting design and development trend

    2012-07-12

    China LED lighting design and development trend
     

    Energy conservation

    Research data shows that due to cold light is LED, semiconductor lighting itself without any pollution to the environment, and incandescent lamp, fluorescent lamp, compared to electricity saving efficiency can achieve 90% above. In the same brightness, power consumption for normal bulb only 1/10 of the fluorescent tubes 1/2. If use LED to replace traditional lighting, 50% of the our country save every year is equivalent to a three gorges hydropower station is the sum total of the electricity, and the energy-saving benefit is very considerable.

    Health

    LED is a kind of green light source. LED for dc drive, no stroboscopic; No infrared and uv ingredients, no radiation pollution, show color of the high and strong directional light; Dimmer performance is good, color temperature changes won’t produce visual error; Cold light source low calorific value, can be safely touch; These are all incandescent light bulb and fluorescent lamp short of. It can provide a comfortable light space, and can meet the demand of physiological health, is to protect the vision and the health of environmental light source. Because the present single LED power smaller, brightness is low, should not be used alone, and will be more LED assembly together become practical design of LED lighting lamps has wide application prospects. Lamps and lighting designer can according to the needs of the object and flux, decided to the shape of the optical system, the lamps and lanterns of LED the size of the number and power; Can also will several LED tube combination design into point light source, ring or face light source of “the second light source,” based on a combination of “second light source” to design lamps and lanterns.

    Art

    Light color constitute the basic elements of visual aesthetics, is an important means of beautification bedroom. The selection of light source directly influence the artistic effect of light, light color display lamps in LED display on art unparalleled advantage; Color LED products has covered the visible spectrum, and monochromatic good, high purity color, red, green, yellow LED to the combination of color and gray (16.7 million color) choice has a greater flexibility. Lamps and lanterns is glowing sculpture, by material, structure, form and texture structure of the material form is also show art lamps and the important means. LED technology make the bedroom lamps and scientific and artistic quality will be better organic union, broke the traditional lamps side frame, beyond the inherent of so-called lamps form of ideas, lamps in the visual perception and form design of art creative performance, with a new point of view to know and understand and express the theme of the light. Can be more flexible use of optical technology in Ming and dark collocation, the combination of light and color, material and structure design of the advantage, improve the design freedom to weaken the lighting lamps function, let the lamps become a visual art, create a comfortable beautiful light artistic effect. For example translucent synthetic materials and aluminum into similar to the candle of LED lamp, can put on the ground, at the corner or desk, conception is contracted and relaxed, form of visual experience of light and convey experience, let lamps with taste and vitality into being.

    Humanized

    Without a doubt, light, and the relationship between people is an eternal topic, “people see the light, I saw the light”, it is a classic discourse has changed countless designer to the understanding of the lamp. Lamps is the highest realm “pressing” is human highest expression of lighting, the room without any trace of the common lamps, let people can feel light but couldn’t find the light source, reflected light and human life of perfect combination of humanized design.
    LED lamps product small qualitative light, can choose different combination of light color LED into illumination soft various modules, any installation in the bedroom, the bedroom lighting lamps light source may result from the ground, metope, window, furniture and decorations. Therefore, the future will no longer limited to bedroom illume a single lamps and lanterns, and will by single lamps lighting into no lighting appliance feeling the whole lighting effect of the pressing. Different light color and brightness to the person’s physiology and psychology can produce different effect, people in many cases don’t need very bright white light, may yellow or other color of light more suitable for physiological and psychological needs. Three colors LED can realize the brightness, gray, color of the continuous transformation and choose, make lighting from in general for a variety of white light expansion color of light.

    Therefore, people can according to overall lighting needs (such as color, brightness and direction, temperature, etc) to set the lighting effect, realizing the humanized intelligent control, create a different indoor illume result. Even if the bedroom only LED ceiling and glowing metope, people can also according to their respective requirements, the scene, as well as to the environment and different understanding of life, in different space and time of choice and control the brightness of the light, gray, color changes, the simulation of all kinds of the light environment to guide, improve mood, reflect more human lighting environment.

  • Intelligent lighting

    2012-07-12

    Intelligent lighting
     

     In the 21 st century after, “smart” into public view, and frequent blink, for example the intelligent building, intelligent community, intelligent small home appliance. That this time we asked, our home can intelligent?

    Hollywood’s science fiction films often appear such a scene: use a computer can for home appliances, curtain, lighting of intelligent remote control, or on the way home in the home lighting control system to control, such a scene should be the public know of intelligence lives in a silhouette. With the development of science and technology, now intelligent household have stepped outside the screen came to our side, it can use high-speed Internet access of special line, doors and Windows, lamps and lanterns household equipments can be controlled by computer, and there is a high performance server as a background management platform, make household becomes more intelligent. Intelligent lighting as part of the smart home, it has the characteristics of how? And can bring us how senses and experience?

    Intelligent scene do change

    Intelligent lighting brings to our life human nature to change, in the intelligent control system of indoor light soft start-up process, and the brightness of the light can be according to the environment, to the memory set. Daily life different atmosphere need different light setup, close the intelligent control system for consumers think of this, it can also set a variety of scene mode. For example at home when they see TV can choose intelligent lighting control of scene way control, this time curtain will automatically closed, the electric lamp light will be weak and the canister light rays of light will be strong; If the home had visitors can do exactly the opposite, this is to receive a visitor scene. If we go home very late, also can start the corresponding intelligent lighting control system, in your way, turn on the light. According to different scene choose different scene lighting, it’s really very humanized design. For the control of the light is not only in the hands of a remote control actually, we can also through the intelligent lighting a terminal control unit, such as the head of a bed controller and network control on ways to realize intelligent lighting.

     Compared with ordinary household lighting system, intelligent lighting control’s good to have green energy saving, environmental protection, convenient, comfortable, even so, intelligent lighting and not like apple products as soon as we walked into the public life, and that the reason?

     According to the author of stylist visit to realize, early years intelligent lighting for a lot of people just a concept, with the progress of social development, the improvement of intelligent building requirements, now more and more designers and architectural design institute have started to pay attention to intelligent lighting. In the household should space, high-end villa basically all use intelligent lighting, but common household space application and not very extensive. In the design stage lighting designers consider these factors in it, from this decorates stylist to consider, but the socialization process different city, and a lot of the owner to the intelligent lighting consciousness not clear, so the range of application is not very extensive.

     Looking forward to the future of the LED performance

     Intelligent lighting dimmer control is an important one part. The lamps and lanterns of traditional only incandescent lamp can be completely realize the function of the move light, energy-saving lamps need to use special models. For LED lamps-external drive the lamps and lanterns of the basic can realize the function of light. It also LED industry for the lighting control system with great opportunity of development.

     LED products used in household lighting a unique advantage is through the intelligent control to create comfortable energy saving lighting environment. LED light source of lamps and the properties of the future intelligent lighting it decided to the direction of development. Just think, the home of the light switch, light and dark or light color can be passed to control as smart phones, isn’t it’s something to look forward to? Believe that with LED technology of development and perfection, photosynthetic efficiency reached the public needs effect, the energy saving effect of LED lighting is no longer simple interest demand point, this time LED intelligent lighting development and will become a big competition points.

     Although intelligent lighting control has not formed the large-scale consumer market, but lamps according to their own enterprise can product differentiation positioning, vehemently to guide the consumer, to explore for intelligent lighting control system of industry development model. Believe in the lamps of enterprises and designers to build the next, there will be more people in a wireless remote control you like or appropriate lighting effect to mix, dazzle beautiful, clever, refined the different style such as light environment let the busy people forget all, build exclusive in his own sweet household world.

  • The modern kitchen lighting design

    2012-07-12

    The kitchen light was a god’s a beautician, it can make the color of the food texture produce subtle change now, cooking is no longer a simple chores, but a sly interest a glass of red wine dinner, match with romantic lamplight, is enjoying life simple explanation

    The kitchen lighting divided into two levels

    The kitchen contains numerous learning with the lamp, the space of the light visual effects and functional, these are also most families need to know. Hutch room lighting basic characteristics of traditional to bright. The stove, furnace frame, sinks, work station should have enough intensity of illumination, meet for food, wash dish, cut vegetables, cooking, request to cook cook cooking purely functional primarily. Along with the change of the kitchen space, kitchen equipment increasingly progress beautiful and practical, modern kitchen more and more diversified requirements of lighting, because the kitchen has become a family meal preparation and emotional communication, study, work and entertainment places. Therefore, modern kitchen lighting requirements should also like other room, full of warmth and comfortable sense, both practical and beautiful, bright and pure and fresh, and both the functional sex of the lighting, to give people the feeling of clean and tidy.

    Apartment common for small kitchen, mainly for the ceiling lamps and lighting source of regional work lighting, and the stove take lampblack of several cooking local lighting. The space is large villas kitchen, lighting on the design of whole space often cooperate, there are different levels with functional lighting design. That is, the kitchen light requirements must be divided into two levels: one is to the whole kitchen basic lighting; A is for washing, equipment eat, operation of the lighting.

    Basic lighting lit up the area, using capacity in 25 to 40 W the ceiling between dome light or droplight, especially with a with embedded absorb dome light, or waterproof dustproof prevent lampblack absorb dome light, this can provide high quality, and the energy saving of the basic lighting. If the kitchen space high enough (2.7 m or so clear height), to install droplight as the light source, droplight not only can then provide excellent lighting, it’s still very good adornment items. Necessary, area more than 12 square metre can pack in the kitchen of two or more chandelier.

  • WHAT TYPE OF LIGHTING IS RIGHT FOR ME

    2012-07-12

    WHAT TYPE OF LIGHTING IS RIGHT FOR ME
     

    General Lighting
     
    These types of lights are usually in the form of recessed lights, surface mounted fixtures, semi flushed fixtures, or hanging fixture.
    Most people think if you already have a service-mounted fixture it is very easy to replace that with recessed lighting, which is a more even light throughout the room. One concern of many people is the amount of heat loss after installing high hats into a space, which has an attic access above.  Not to worry because the new recessed lights have gaskets and are constructed to be airtight.  What this means is that it is almost like the ceiling was never opened and that a surface mounted or hanging fixture actually will have more heat loss.
     
    Task Lighting
     
    There are many different kinds of task lighting, such as pendants over islands and peninsulas, chandeliers over tables and scones over vanities.  Two of my favourite types of task lights are under cabinet lights and closet lights.  Under cabinet lighting is special because it is multifunctional.  When you are cooking, it provides the illumination needed on the counter top but when the cooking is done and the lights are dimmed, it serves as a nice night light for your kitchen area.
     
    Accent Lighting
     
    It is a way of creatively adding illumination while calling attention to the things in which you are most passionate.  One way to accentuate the architecture is to lay rope lighting in the modelling of a tray ceiling and watch the ambience of light that is cast from atop the tray. One of the great things about this type of lighting when used with artwork is when the amount of light on the artwork is adjusted the colour appear to change before your eyes.   Another example of how to use lighting creatively is by illuminating your favourite plants.  They can be lit by overhead lighting to capture the surface colours of your favourite plants or by lighting from underneath where light is filtered through your foliage creating a unique cascading effect.

  • IS IT TIME TO UPGRADE TO LED

    2012-07-12

    Progressively customers are turning their eyes towards LED house lights as a method to save electricity. But will you really achieve the greatest savings by buying this still expensive lighting now? Or would you be better off to save your money for the time being, or to buy other energy-efficient light bulbs, and use the money you save in electricity to buy LED house lights down the road?
     
     Everybody has seen LEDs before: LED Christmas tree lights, wind-up emergency torches, and camping headlamps. How about LED house lights? If LEDs are so effective, why aren’t manufacturers lining up to sell LED lights for the home, and why aren’t we lining up to buy them?
    To be fair, I think LEDs have a ways to go yet, in terms of function, durability, and budget. There are some LED products you should consider over the next year, such as LED Christmas lights. And you might enjoy trying out a couple of LED light bulbs, if you’re the energy-saving type. But is this going to save your money? Compact fluorescent lights, or CFLs, are so cheap that they’ll pay for themselves.

    One thing, LED light bulbs are more efficient than incandescent or fluorescent lighting. The problem is that LEDs have very directed light. An incandescent light shines over an extensive area, while LED lights are very focused, so that the area they directly illuminate is very bright, while the further you go from the direct beam, the less light there is. For LED Christmas lights, that isn’t a problem; you just want some shining points of light, which LEDs do very efficiently. But an incandescent or CFL will do a much better job of brightening up your living room than an LED bulb in the same application. The light will be more evenly and generally spread, and with a warmer colour.
     
    When it comes to halogen lights, they are only as efficient as incandescent lights, so the same efficiency considerations apply here. But since halogen lights are typically much more direct than incandescent bulbs, LED lights that are designed to replace halogen lights and work well for the direct light that halogen bulbs provide. You can find LED replacement bulbs for the most common halogen fixtures such as GU10 and MR16, and this may be a good place to start the switchover.
     
    LED house light designers work around the issue of the narrow beam of a single LED, by building household LED light bulbs that are a collection of individual LEDs, with each diode aimed at a different angle, so that a wider area is highly illuminated. This increases the area of full light coverage of an LED light. However very few such bulbs provide the breadth of area coverage of existing incandescent bulbs or CFLs and at the same time are bright enough.
     
    Where LED lights overtake existing bulbs is as replacements for lighting that is highly directed. For example, a light in a narrow hallway, where the chief point of the light is to show people their way down the hall, would be a good application for LEDs.
    Task lighting is another example of an application where LEDs shine. Why light up your entire workroom if all you need to see is the tools on the workbench right before your eyes? A couple of LED bulbs hanging above the work area will do the trick nicely. But you can only cost-justify this in energy savings if you live half your life in the workroom.
     

    LED light bulbs are, in theory at least, very durable, when compared to incandescent bulbs and compact fluorescent bulbs. LED bulb life ranges from 35,000 to 200,000 hours, compared to 1,000 hours for a good incandescent light, and 8,000 hours for a CFL. But I have seen many consumer ratings of LED bulbs that report burnout within a few days of being switched on. Clearly there are some quality problems still to be worked on – yet another good reason for holding off a couple of years before switching wholesale to LEDs.
     
    Whether LEDs will really live up to their long lasting billing remains to be seen – even the 35,000 hour ones would need to be on 24×7 for 4 years before they come close to reaching their advertised range. And LED lights do dim with age – so while a bulb might have a lifetime of 35,000 hours, it won’t emit its starting light level for the full 35,000 hours – the older it gets, the less light it will emit. LED lights do decline progressively in light intensity and therefore in efficiency, although they will still be more efficient than either CFLs or incandescent bulbs throughout their life.
     
    The “colour temperature” of a light bulb, measured in ‘degrees Kelvin’, regulates human visual response to its light. You are probably comfortable with the yellowish glow of incandescent at around 2800 Kelvin (2800K), even though fluorescent lighting is closer to the natural daylight temperature of 6000K. Any LED with a temperature of 6000K or higher will seem bluish, and any LED with a colour temperature above 4000K will appear whiter than an incandescent bulb.
     
    While homeowners are typically worried about how fluorescent or LED lights can make their rooms look blinding white instead of the comforting yellow glow provided by incandescent bulbs, you should remember that a little sacrifice in colour temperature will put a big dent in your electricity bill. Be a trendsetter, not a trend-follower – start converting your home lighting to true daylight colours, whether with CFL lights or LED light bulbs. You will be helping your family and friends to switch over; when they find out they won’t be the only ones with a slightly bluer light hue in their homes.
     
    Whether you switch a few of your lights to LED lights now, or let the technology and reliability improve, you can count on the fact that LEDs will play an increasing role in lighting our houses in the years ahead. I personally think it makes sense to wait, except in certain special lighting situations where the direct, high-colour-temperature light of LEDs is what you’re after, and where money is no object. If you just want to save money – or to cut your energy use for environmental reasons – an equal amount of money spent on CFLs, or most other energy efficiency upgrades, will cut your energy bills and carbon footprint more than buying the LED lights now available.

  • LED-Illuminator or Indicator

    2012-07-12
    LED-Illuminator or Indicator
     

    There has been a lot of talk about LED lighting over the last couple of years. Manufacturers originally made claims that these lights would last 100,000’s of hours and quickly they discovered that this was in fact not the case. Most high quality LED products are rated to 50,000 hours but the truth is that by the time the light fitting has reach half of this usage, it will not be radiating nearly as much light or even the same colour light as it originally did.
     
    Claims that you could (affordably) replace a standard down light with a LED and still achieve the same amount of light were also made and quickly retracted. The reality is thatLED lights will play a major role in the future of the residential lighting industry. This is because high-quality LED’s will last many thousands of hours – long enough to conclude that you will get “a lifetime of use out of each fitting”. They will also use considerably less energy than halogen downlights. However, currently there are many LED downight replacement options that are just not up to scratch. There are some very good, high quality products available, but they are currently not a cost effective solution for general lighting in the mainstream community.
     
    A very effective way to use this technology is as an indicator or task based light source. There are fantastic fixtures available on our website that offer low energy and zero maintenance solutions to task and indicator type fixtures. Good examples of this type of fitting would be outdoor spike lights and deck lights, reading lights, picture lights, step and passage way lighting. LED lighting is very well suited to outdoor use because they will provide many years of maintenance free usage. Therefore, the fittings don’t need to be opened to change globes and the risk of compromising watertight seals is reduced. In addition, LED lights do not generate a lot of heat and so they are immune to the “Siphoning Effect” that has plagued the traditional outdoor halogen fittings (standard halogen globes generate extreme heat and so when they are used outdoors they are prone to the “Siphoning Effect” whereby moisture is sucked into the fitting through any compromised seals or cabling as the light fitting cools down).

  • Switch to Energy-Saving

    2012-07-12

    If you want to change the world, start by changing a few light bulbs. It is one of the best things you can do for the environment – and your budget.
    In the 1880′s, light bulbs had revolutionized the world. Today we all call them “lights”, traditional incandescent bulbs are actually small heaters that produce a little light but they also waste a lot of energy making the heat.
     
    Reasons to Switch to Compact Fluorescent Light Bulbs:
    The first reason is, replacing one regular light bulb with an approved compact fluorescent light bulb will save you $30 in energy costs over the life of the bulb.

    The second and also very important reason is that Compact fluorescent light bulbs also generate 70 percent less heat, so they are safer to operate and can also reduce energy costs associated with cooling homes and offices.

    The third and most important reason is that a Compact fluorescent light bulb use at least two-thirds less energy than a standard incandescent bulb to provide the same amount of light, and they also last up to 10 times longer.
     
    Choosing the Right Compact Fluorescent Light Bulbs:
    To make sure you get the same amount of light when replacing standard bulbs with compact fluorescent light bulbs, check the lumen rating on the light you are replacing and purchase a compact fluorescent light bulb with the same lumen rating.
    Wattage varies greatly between standard light bulbs and compact fluorescent light bulbs. Compact fluorescent light bulbs typically use about one-quarter of the wattage used by standard bulbs to produce the same amount of light. So to replace a traditional 60-watt bulb, look for a compact fluorescent light bulb that is about 15 watts.
    Compact fluorescent light bulbs are available in many different sizes and shapes to fit in almost any fixture—from three-way lamps to dimmer switches—for both indoor and outdoor use. Compact fluorescent light bulbs also come in a variety of color temperatures, which helps determine the color and brightness of the light each bulb provides.
    The Different Colour Temperatures:

    Generally there are three different Colour temperatures for Compact Fluorescent lamps. Colour Temperature is a measurement in Degrees Kelvin that indicates the hue of a specific type of light source.

    Warm White is between 2700k and 3000k.
    Cool White is between 4000k and 4200k
    Daylight is between 4800k and 5000k

    You will get a better idea of the different Colour temperatures if you have a look at the following chart.

    To find the right lamp you need also an idea of which lamp base you need for your lights.
    The following text will show you the different types of globes and describes what they are used for the most.
    The Different types of lamp bases:

    Edison Screw (ES, E27) (small: SES, E14)
    Replacement low energy lamps are available with ES caps

    Bayonet (B22, BC) (small: B14, SBC, B15)
    The bayonet cap is not the safest of caps as the lamp holder has bare connection that you can touch if the bulb is removed.

    GU10
    High Voltage
    GU10 lamps are often spot lights, used in recessed downlighters.
    GU10 is one of the safest types of mains voltage lamp holder as all the electrical live parts are concealed even when the lamp is removed.

    MR16
    MR16 lamps are low voltage usually running at 12v. the pins are 5.3mm apart.
    The most common use for this lamp cap is for spot lights, in recessed or decorative light fitting.

     
    GX53
    This is a Compact Fluorescent Lamp that is mainly used for recessed lights, ceiling fan lights and cabinet lights

    CFL's Buying Guide
     

    News
    In the last few years the sales of energy saving lamps have increased. Compact Fluorescent Lamps are replacing more and more the less efficient incandescent lamps because they need less power and have a longer rated life. Some of you may now think that you don’t have the same advantages with these globes as you can’t dim them. This is wrong. New technology makes it possible to dim the CFLs.
     
    · CFLs need less power while having a longer life
    ·  New technology makes it possible to dim CFLs
     
    Dimmable CFLs
    You cannot dim all CFLs. If you want a dimmable lamp you need a purpose built CFL. Check the information on the packaging to be sure you buy the right globe.
     
    Two different dimming technologies

    ·         usual   dimmable CFL
    ·         switch dimmable CFL
     
    If you decide to have a usual dimmable CFL you can buy a lamp from the Megaman Dimmerable Series. The lamps have a range of 10% to 100% and it dims perfectly smooth with most incandescent dimmer circuits and dimmer switches.Megaman Dimmerable Energy Saving Lamps are compatible with most types of dimmer switches and dimmer systems.
     
    If you don’t want to install a dimmer circuit you should get a switch dimmable light. You can dim the light by switching the on/off bottom. The Megaman Dors Dimming series has the 4 step dimming of Megaman Energy Saving Lamps on almost any standard (On/Off) switches. You can choose between a brightness of 100%, 66% 33% and 5%.
     
    NOTICE
    When you choose one of these two systems it is really important that you use dimmable CFLs especially when you install the lamp in a dimming circuit. So check the information on the packaging carefully that you can be sure to have the right lamp type.
     
    Using a non-dimmable CFL
    If you try to use a non dimming CFL in a dimming circuit it won’t work efficiently and the life of the lamp will be much shorter. You also won’t be able to claim the warranty back in most cases(depending on the manufacturers terms and conditions of their warranty).
     
     Costs
    Dimmable CFLs are three to five times more expensive than non dimming CFLs. This is because they require much more electronic circuitry. It also makes them bulkier then normal CLFs.
     
    Sorts of dimmer
    There are different sorts of dimmers on the market. For dimmable CFLs you should use leading edge electronic dimmers or trailing edge electronic dimmers. They will operate optimally with one of these technologies. You should buy the correct lamp for the type of dimmer you have.
    Most of the lamps will also work with the wrong circuit but not efficiently. It could be noisy and the functionality could be limited. Another dimmer type is the rheostat dimmer. It is not compatible with any CFL.
     
    Difference between dimmable CFLs and incandescent lamps
    The biggest difference between incandescent and CFL dimmable lamps are that you can dim the incandescent down to zero and CFLs just down to 10-20 percent. The reason is that there must be an arc between the lamps cathodes and for this you need a certain amount of current.
