(Watts are a measure of energy used and are named after inventor James Watt.) The higher the number of watts, the more electricity the bulb uses and the brighter the light will be. CFLs are more efficient because instead of pushing electricity through a wire, they allow the electricity to flow through a glass tube and light up a combination gas and chemicals called argon and phosphor
Edison experimented with thousands of different light bulb filaments to find just the right materials to glow well, be long-lasting, and be inexpensive. Edison was quoted as saying, "Genius is one percent inspiration and 99 percent perspiration." On October 21, 1931, a few days after Edison's death, electric lights in the United States were dimmed for one minute

Edison and his staff examined six thousand organic fibers from around the world, searching for a material that would glow, but not burn, when electric current passed through it. Edison also developed the fluoroscope (an instrument used to study the inside of the living body by X rays), but he refused to patent it, which allowed doctors to use it freely
Thomas Edison
All the article states is that it is doubtful in my opinion if our intelligence or soul or whatever one may call it lives hereafter as an entity or disperses back again from whence it came, scattered amongst the cells of which we are made." Nonviolence was key to Edison's moral views, and when asked to serve as a naval consultant for World War I, he specified he would work only on defensive weapons and later noted, "I am proud of the fact that I never invented weapons to kill." Edison's philosophy of nonviolence extended to animals as well, about which he stated: "Nonviolence leads to the highest ethics, which is the goal of all evolution. Edison is the fourth most prolific inventor in history, holding 1,093 US patents in his name, as well as many patents in the United Kingdom, France, and Germany
Thomas Edison's Inventions - Business Insider
was so productive that at one point, he promised to turn out "a minor invention every ten days and a big thing every six months or so." All told, he played a vital role in shaping the modern world. Although the man from Milan, Ohio purchased many of his patents and is falsely credited with others (like the lightbulb), he was responsible for many useful creations
The teacher told someone she thought there was something wrong with Alva; that he was "addled".* He told his mother and they took him out of the school. In addition to the electric light, he also invented the phonograph,* a camera to take motion pictures, a cement mixer, the automatic* telegraph, and he improved Alexander Graham Bell's telephone
It is a testament to how great a job Edison and his workers at Menlo Park did in taking this invention out of the laboratory and putting it into the home. How big would the generator need to be to light a neighborhood? What voltage should be delivered to a house? By October of 1879 Edison's workers began to see some results
Thomas Edison - Inventions - HISTORY.com
Thomas Edison received little formal education, and left school in 1859 to being working on the railroad between Detroit and Port Huron, Michigan, where his family then lived. In the interim, he had had success developing an alkaline storage battery, which he originally worked on as a power source for the phonograph but later supplied for submarines and electric vehicles
You might begin by asking students to brainstorm, in small groups or as a whole group, what they think life and technology were like in the early 1900s. Make sure the students understand that technology is the product of scientific research, and that usually those products serve industry, like machines, or people, like computers, stereos and televisions
Who Invented the Light Bulb?
Tungsten, which has the highest melting point of any chemical element, was known by Edison to be an excellent material for light bulb filaments, but the machinery needed to produce super-fine tungsten wire was not available in the late nineteenth century. Unfortunately for Swan, the vacuum pumps of his day were not efficient as they are now, and his first prototype for a cost-effective bulb never went to market
No wonder Edison said, "Genius is one percent inspiration and ninety-nine percent perspiration!" These three inventions are considered Edison's greatest: the electric light system, the phonograph and motion pictures.

Edisons daily strategies for success and creativity continue to provide meaningful insight and inspiration
Because of Edison's poor health, the Edison family spent winters in Fort Myers, Florida, where they entertained friends including Henry Ford, owner of the Ford Motor Company, and Harvey Firestone, founder of a large automobile tire manufacturing company. He invented a system for filming and showing movies, but within 20 years, the field became so competitive that he withdrew from the motion picture industry
Thomas Alva Edison: The Improvement of the Light Bulb
Until 1878 when Edison decided to throw the bulk of his attention and resources into the perfection of the light bulb the best source of lighting was gas. Soon, by changing the shape of the filament to a horseshoe it burned for over 100 hours and later, by additional improvements, it lasted for 1500 hours
Thomas Edison: Inventor of the light bulb and much more.
Light Bulb - Although he did not invent the first electric light, Edison made the first practical electric light bulb that could be manufactured and used in the home. Many of his inventions were group efforts in his large invention laboratory where he had many people working for him to help develop, build, and test his inventions
Thomas Edison Invents Light Bulb and Myths About Himself
It has the property of resisting the heat of the current of electricity, while at the same time it becomes incandescent, and gives out one of the most brilliant lights which the world has ever seen. What pervades these unusual arrangements is the conviction that unless this bargain has been compulsively adhered to, the talent may be compromised or even irretrievably lost
The inventor Thomas Alva Edison (in the USA) experimented with thousands of different filaments to find just the right materials to glow well and be long-lasting. Lewis Howard Latimer (1848-1928) improved the bulb by inventing a carbon filament (patented in 1881); Latimer was a member of Edison's research team, which was called "Edison's Pioneers." In 1882, Latimer developed and patented a method of manufacturing his carbon filaments
An honors graduate from the University of North Carolina at Asheville where he concentrated in sociology and political science, he later earned a Masters degree in social work from the University of North Carolina at Chapel Hill. To make it functional, each step required the invention of a new component, from vacuumed and sealed glass bulbs to switches, special types of wire and meters
Light Bulb History - Invention of the Light Bulb
Fifteen years later, in 1875, Swan returned to consider the problem of the light bulb and, with the aid of a better vacuum and a carbonized thread as a filament. Then, in 1879, he invented the ightbulb, and houses, shops, factories, schools, streets, ballparks -- every place you could think of, indoors and out -- could at last be easily illuminated after dark
His helpers, who worked with Edison at the light company, spent time on developing other inventions with him that helped the electric systems work, such as switches, fuses and wires. The three inventions considered Edison's greatest are the electric light system, the phonograph, and a motion picture machine that was a forerunner of the movie camera
The Inventions of Thomas Edison
Although apparently intrigued, Edison decided not to participate in such a partnership, perhaps realizing that the Zoopraxiscope was not a very practical or efficient way of recording motion. There are a couple of other interesting things about the invention of the light bulb: While most of the attention was on the discovery of the right kind of filament that would work, Edison actually had to invent a total of seven system elements that were critical to the practical application of electric lights as an alternative to the gas lights that were prevalent in that day
