Michael Farady of England created electricity through magnets. And people before him knew about electricity for long time, so its difficult to answer who invented it.

Edison did not invent the electric lightbulb, which was pioneered by Heinrich Goebel in 1854. Goebel's lamps lasted up to 400 hours, but he did not patent them. Other light bulbs were created by James Woodward and Matthew Evans (patented in 1875) and equipped with carbon filament by Joseph Swan in 1878. However,it was Edison's relentless and endless experimentation that made the lightbulb a practical, commercial proposition. He purchased the 1875 patent and had a team of developers try many alternative materials and thus was eventually able to prolong the burning time in 1879.\nOn November 21, 1877 and he demonstrated the device for the first time on November 29 (he patented it on February 19, 1878).  , Edison invented the phonograph.\nEdison patented the Kinetoscope on August 31, 1887.

DAGUERRE, Louis Jacques Mande\nb. 18 November 1787; d. 10 July 1851 \nDaguerre (pronounced Dagair) was perhaps the most famous of several people who invented photography. \nHe began work as an apprentice architect, and at the age of sixteen was an assistant stage designer in a Paris theatre, his elaborate stage designs winning him considerable acclaim. He had an astonishing ingenuity in the handling of light and lighting effects, and he supplied the scenic and lighting effects for a number of operas in theatres in Paris. He developed an impressive illusions theatre, which he termed Diorama; it was a picture show with changing light effects and huge paintings measuring 22 by 14 metres, of famous places. This became the rage in the early twenties. \nHe regularly used a camera obscura as an aid to painting in perspective, and this had led him to seek to freeze the image. In 1826 he learned of the work of Nicephore Niépce, and on 4 January 1829 signed up a partnership with him. \nThe partnership was a short one, Niépce dying in 1833, but Daguerre continued to experiment. He made an important discovery by accident. In 1835, so the story goes, he put an exposed plate in his chemical cupboard, and some days later found, to his surprise, that the latent image had developed. Daguerre eventually concluded that this was due to the presence of mercury vapour from a broken thermometer. This important discovery that a latent image could be developed made it possible to reduce the exposure time from some eight hours to thirty minutes. \nThough he now knew how to produce an image, it was not until 1837 that he was able to fix them. This new process he called a Daguerreotype. \nDaguerre advertised his process and sought sponsorship, but few seemed interested. He then turned to Francois Arago, a politician, who immediately saw the implications of this process, took his case up, and the French government commissioned a report on the process, to be chaired by Paul Delaroche. On 7 January 1839 an announcement was made of the discovery, but details were not divulged until 19 August when the process was announced publicly, the French government having bought the rights to the process from him, and given it free to the world. However, this process had also been patented in England and Wales on 14 August - only five days previously. As Lady Eastlake pointed out: \n"...by some chicanery a patent for the daguerreotype was actually taken out in England, which for a time rendered this the only country which did not profit by the liberality of the French government. The early history of photography is not so generous in character as that of its maturity." \nFrom the day the announcement was made of this new discovery, the process came to be used widely. The claim was made that the daguerreotype "requires no knowledge of drawing...." and that "anyone may succeed... and perform as well as the author of the invention." \nThe Literary Gazette for 7 January 1839 read: \n"Paris, 6th January 1839. \nWe have much pleasure in announcing an important discovery made by M. Daguerre, the celebrated painter of the Diorama. This discovery seems like a prodigy. It disconcerts all the theories of science in light and optics and, if borne out, promises to make a revolution in the arts of design. \nM. Daguerre has discovered a method to fix the images which are represented at the back of a camera obscura; so that these images are not the temporary reflection of the object, but their fixed and durable impress, which may be removed from the presence of those objects like a picture or an engraving." \nAn article in La Gazette de France, of the same date, also showed one of the limitations of the process: \n"Nature in motion cannot reproduce itself, or at least can do so only with great difficulty, by the technique in question. In one of the boulevard views.... it happened that all which moved or walked did not appear in the drawing

According to Wikipedia, celluloid was invented by an Englishman Alexander Parkes in 1856 who thought of it as a waterproofing material. Another Englishman Daniel Spill developed a similar product soon after. The Hyatts later developed it as a replacement for ivory in making billiard balls. \n\nBritannica on the other hand gives the credit to Hyatt. Encarta gives Hyatt the credit for refining into the "first practical synthetic plastic".  The short answer to your question is billiard balls.

The Invention of the Light Bulb: Davy, Swan and Edison\n\nThe first electric light was made in 1800 by Humphry Davy, an English scientist. He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. This is called an electric arc. \nMuch later, in 1860, the English physicist Sir Joseph Wilson Swan (1828-1914) was determined to devise a practical, long-lasting electric light. He found that a carbon paper filament worked well, but burned up quickly. In 1878, he demonstrated his new electric lamps in Newcastle, England. \n\nIn 1877, the American Charles Francis Brush manufactured some carbon arcs to light a public square in Cleveland, Ohio, USA. These arcs were used on a few streets, in a few large office buildings, and even some stores. Electric lights were only used by a few people. \n\nThe 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. In 1879, Edison discovered that a carbon filament in an oxygen-free bulb glowed but did not burn up for 40 hours. Edison eventually produced a bulb that could glow for over 1500 hours.

Simply put:  it is the luminous intensity expressed in candelas. ( the brightness of light compared to a candle)\n\nA candela is a measurement of the intensity of light, used in the International Standard (SI) measurement system. In the modern age, it is technically defined as the intensity in a given direction of a source that emits monochromatic radiation of a frequency of 540 x 10^12 hertz and which has a radiant intensity in the same direction of 1/683 watts per steradian.\n\nThe candela as a unit of measurement grew out of the desire to adopt a standard method to measure light. In the 19th century, each country had its own measure of light, most extremely difficult to reproduce with accuracy. At the beginning of the 20th century, groups of nations began adopting new standards, such as the international candle, which were based on a single type of lamp and much more consistent. Eventually, in the 1930s, it was decided that a more precise definition was needed.\n\nInitially, the candela was defined as the luminous emission of a Planckian radiator, a type of blackbody, at the temperature of freezing platinum (2045 K). This correlated roughly to the light emitted by a typical candle, making it a suitable measure. In the late 1970s, it was determined that the experimental difficulties in creating a Planckian radiator at such high temperatures made the existing definition of candela less than desirable. The new breakthroughs in radiometry allowed scientists to have a more specific definition, and so the current hertz/watts definition of candela was adopted.\n\nOne reason the watt was not initially tied to the candela is the eye’s differences in seeing various wavelengths of light. Since the human eye is less observant of blue and red light, more wattage is needed to produce the same result in the brain as with yellow or green light. This is why the definition of candela is defined as a very specific hertz, unachievable in actual common lighting. There are those who critique the modern definition of the candela for this reason, arguing that it has removed any common-sense understanding of the candela as an actual emission of light.\n\nThe reason the modern definition of candela includes the somewhat bulky 1/683 watts per steradian is to make it conform to the previous definition, in order to avoid any confusion when comparing the modern unit to the historical candela. In this context, the steradian is the cone of light as it emerges from the source, such that it would light up one meter square of the inside of a sphere with a one meter radius.\n\nSince the precise definition is so unwieldy, it is not uncommon in standard usage to see the candela referred to as “roughly” the amount of light generated by a single candle. This definition is perfectly suitable for common usage, as is the translation of 120 candela to roughly the light emitted by a 100 watt light bulb.

The invention of the microscope is variously accredited to Zacharias Janssen, a Dutch spectaclemaker, c.1590, and to Galileo, who announced his invention in 1610.

Edison invented the light bulb. It was a bit of inspirational genius that took many tries before he got it right. The idea was good but putting in all the effort to make the idea work was how the inspiration became genius.
