LED lighting is replacing fluorescent and incandescent in many cases. LED lighting is much more efficient than incandescent, and about the same as fluorescent. However, LEDs are expensive, requiring a huge initial investment. There are claims they will pay back the investment over time because they last a long time and require low maintenance, but not everyone believes those claims and LEDs have not been around long enough to know.
LEDs, fluorescent and incandescent provide different qualities of light so some sources are better for some applications. For example, only incandescent is full spectrum.
Also, LED lamps can only be made in limited light output for size, due to the problems with removing the heat they generate. Some new LED lamps have fans or other active cooling mechanisms.

What size wire is utilized in low voltage systems?
If you are referring to low voltage lighting systems the current usually dictates 10 or 12 AWG, 10 is more common in my experience and the wire usually used is stranded.
How can you connect single phase generator in three phase supply system in house lighting system?
First house lighting systems are single phase not three phase. To connect a generator to the house lighting system for emergency power, it would take an electrician to do the job properly. The biggest concern would be to isolate the rest of the service from the main distribution supply service and then isolate the rest of the distribution panel loads from the lighting loads.
Who was the inventor of fluorescent lamps?
The term "Fluorescent" dates back to approximately 1845-1852 where the English mathematician-physicist George Gabriel Stokes from Cambridge University named this "phenomenon" after fluorite, a strongly fluorescent mineral.The invention of the fluorescent light is a string of discoveries and developments by many people in several countries. It was developed over 80 years since the invention of the working electric light bulb by Thomas Edison. Like so many things that we take for granted today, fluorescent lighting is the result of numerous small additions to the knowledge and technology of the time.The development started with experiments in the 1840s by British scientists, George C. Stokes, Michael Faraday and James Clerk Maxwell. A German glass blower, Heinrich Geissler, continued with the experiments and in 1856 produced a vacuum tube that would produce a green glow when a current was passed through it. The tube had little practical value because the green light didn't provide useful illumination. However, Julius Plucker and Alexandre Bequerel experimented with the tube. Bequerel discovered that certain minerals glowed when they were in an operating tube and added coatings to the inside of the tube that would glow.At the 1893 World's Fair, the World Columbian Exposition in Chicago, Illinois displayed Nikola Tesla's fluorescent lights.In 1896, Thomas Edison put a calcium coating into the tube and generated useful light. The short life of the tube meant that it never went into production. Nicola Tesla contributed with variations of the tube, again without producing a commercial product. Daniel Moore continued Edison's work and 1904 saw his tubes being used commercially for some limited applications.In 1894, D. McFarlane Moore created the Moore lamp, a commercial gas discharge lamp meant to compete with the incandescent light bulb of his former boss Thomas Edison. The gases used were nitrogen and carbon dioxide emitting respectively pink and white light, and had moderate success.An American engineer, Peter Cooper Hewitt (1861-1921) developed the mercury vapor lamp at the same time. It produced yet another green light output so its practical application was limited.Peter Cooper Hewitt patented (U.S. patent 889,692) the first mercury vapor lamp in 1901. The low pressure mercury arc lamp of Peter Cooper Hewitt is the very first prototype of today's modern fluorescent lights.In France, George Claude made neon and argon tubes which glowed red and blue respectively. Although it was not of practical use for illlumination, the neon tubes employed electrodes that were longer lasting than others of the time. Fellow Frenchman Jacques Risler added a fluorescent coating to Claude's tubes and his product made it to commercial production.In Germany, Friedrich Meyer, Hans-Joachim Spanner, and Edmund Germer all worked on low pressure vapor lamps. Although they achieved technical success, their lamp was never manufactured commerically.General Electric had interests in the new lighting technology and had purchased several patents including Germer's. It came down to George E. Inman and his team of engineers at GE to turn the technology into a commercially viable product. There were a number of legal battles that were fought during the 1920s and 1930s to establish the rights to the technologies. Because of the number of people who contributed to the product, there were numerous patents that affected it. Commercial sales of fluorescent lamps by GE commenced in 1938.It has been reported that Agapito Flores, a Philippino inventor, received a French patent for a fluorescent bulb and that the General Electric Company bought Flores' patent rights and manufactured and sold his fluorescent bulb (making millions from it). However, all the inventors named above and more predate Agapito Flores' possible work on any fluorescent bulb.According to Dr. Benito Vergara of the Philippine Science Heritage Center, "As far as I could learn, a certain Flores presented the idea of fluorescent light to Manuel Quezon when he became president. At that time, General Electric Co. had already presented the fluorescent light to the public."There are other names that do not get mentioned in this brief answer. Each person made their own important contribution and although they are not mentioned, credit should be given to each person who experimented, played, observed and developed the science and technology surrounding the development. Although the early part of the 20th century saw large companies funding and sponsoring inventors and developers, there were many who carried out work without other funding. Perhaps it is the independent experimenters who deserve special recognition for their work.See the related links below for more information about the history of the fluorescent lamp.Bondi Junction Edgecliff Kings s\

Does it cost more to use led lights than regular lights?
It is very much a case of a balance between a factor of 5-6 in favour of the led system in power consumption, the capital expense of replacing a light when it fails, and the frequency of failure. The capital cost (Australian prices) was around 50 to 60 in favour of the cheapest quality incandescent bulbs, but it is no longer possible to buy an incandescent bulb in Australia. That comparison applied between the price of the cheapest bulbs when they went off the market and today's price for a led system. Depending on how they were operated, you could expect an average lifetime of about 6 months for a cheap incandescent bulb as against about 5 years for a led system. So you will see that the various systems of illumination come out much the same, as does compact fluorescent lighting. Incandescent lighting produces large volumes of waste which is fairly non-toxic and possibly recyclable. Compact fluorescent lighting produces considerably smaller volumes of waste which is, however, toxic and much more damaging to the environment. Led systems produce really tiny amounts of waste -- I am not really sure how toxic or environmentally damaging it can be

How is technology used in lighting homes?
Energy efficient lighting is an excellent way to save electricity, save money, and help the environment while satisfying your home decorating itch. People often overlook the importance of lighting their homes with fixtures that reduce the number of watts spent on keeping the indoors (and outdoors) bright. A good way to get away from the old, inefficient incandescent bulbs is to look into lighting your home or office with low voltage, LED lights, or fluorescent lights. There are drawbacks and benefits to all three of these types of light bulbs, but any of them are more efficient and longer lasting than traditional incandescent bulbs. According to The International Electrotechnical Commission, low voltage appliances function by using electricity in the range 50-1000 V AC or 120-1500 V DC. Energy Star light fixtures often use low voltage and are characterized by carrying a reasonably substantial risk of electric shock (so professional installation is encouraged), but only a minor amount of electricity actually arcs through the air. Low voltage lights (especially outdoor low voltage lighting systems) are often time consuming to install but last significantly longer than traditional incandescent bulbs so they are a good choice for outdoor lighting in a commercial setting. Fluorescent lighting fixtures are also great energy savers when it comes to home lighting. A fluorescent light is a gas-discharge lamp that uses electricity to excite mercury vapor. The mercury atoms create short-wave ultraviolet light rays that then cause a phosphor to "fluoresce", producing visible light. A fluorescent lamp changes electrical power into useful light more efficiently than an incandescent lamp through this method. The lower energy cost of fluorescent light fixtures typically offsets the higher initial cost of the lamp itself. The fluorescent light fixture is more expensive because it is necessary to install a ballast to regulate the current through the light, but the life of a fluorescent bulb is typically much longer than a traditional bulb with a life span that is 10 to 20 times longer than a regular incandescent fixture. The compact fluorescent light bulb is also less likely to create a glare and covers a larger area with light without concentrating too much of it on one point. In this way you can light an entire room with only one or two fixtures (saving you energy through the number of light fixtures as well as the amount of electricity used to light them). LED Lighting is another great option for going green in your home decor. There are a lot of reasons why lighting designers are turning towards LED technology when considering designing their next lighting masterpiece. Some of the most obvious advantages to LED lights over CFLs (short for "compact fluorescent lights") is that they don't contain mercury so there's no need to dispose of them in special fluorescent bulb recycling programs. Source: http://www.epa.gov/osw/hazard/wastetypes/universal/lamps/ Mercury can find its way into streams and rivers, and therefore fish and drinking water. Exposures to mercury can affect the human nervous system and harm the brain, heart, kidneys, lungs, and immune system. The most common way we are exposed to mercury is by eating fish or shellfish that are contaminated with mercury, but this can be prevented by careful disposal of fluorescent light bulbs through official recycling programs developed by the EPA. With LED (short for "light emitting diode") lights, there is no risk of mercury contamination and little to no risk of electric shock and they use such little wattage that you will see a definite change for the better in your electric bill. LED lights are everywhere now, and for a good reason. They help the environment, save electricity, last longer than incandescent AND fluorescent lights, and are much more easily programmed to do a variety of tasks. In fact, energy-saving LED lighting is up to 70% more efficient and often comes with 10 to 15 year warranties from the manufacturer. You'd be surprised where you'll find LEDs--in remote controls, in DVD players, traffic lights, and even kitchen appliances. So it's no wonder that LEDs are sweeping the market in home lighting design, being featured in wall sconces, landscape lights, and even designer chandeliers. In conclusion, there are many ways to "go green" that are simple, affordable, and easy to install. It's amazing how you can save so much energy over time by simply investing in smarter light fixtures to brighten up your home, office, store, or outdoor landscape. California has even begun phasing out incandescent bulbs by banning them from being manufactured as of January 1st, 2011. So if you're ready to jump onto the green revolution bandwagon, a great place to start is in the lighting department.
