To Provide more reliable light. The creator of the light bulb Thomas Edison noticed that the number of fires were increasing because of the candles catching alight on peoples houses. Creating a light bulb would result in less fires and a safer way to access light that doesn’t run out.
While candles were a good idea it became increasingly obvious that they were the most common cause of fires burning people’s houses, and polluting the air, making the city very congested. They needed a safer and more reliable source of light that lasted longer. People eventually got sick of the pollution. Tallows were the most common candles people used as they were the cheapest they were made out of animal fat and put into moulds. They had a very smoky flame which contributed largley to the pollution as well as smelling foul. They also used two other types beeswax which smelt good and was made out of beeswax obviously. There was also spermaceti is a candle that has been made out of the fat out of the head of a sperm whale.
The first light bulb was made in 1879. Light bulbs became very popular as they quickly proved that they lasted longer and they were safer, people started installing them all over their houses and they were accessible with a simple switch.The solution was that Thomas edison decided that the only way to stop the fire was to create a safer solution, at first many people weren’t on board with this idea but soon realised that this is a safer option. For the light bulbs to be installed they had to be tested a number of times, they would have failed quite a bit before they finally became perfect and were able to be used.

In fact they were unsuccesfuly tested it 1000 times before getting the result he wanted. Thomas edison spent a long time perfecting the light bulb so it could be used in houses but the main thing he wanted was for it to be cheap easy to pay for so then many people could have light bulbs throughout their houses whether they were poor or very wealthy. Thomas edison also tried to make it good quality as well as cheap but then found other ways to make them better using more expensive materials which lead to some light bulbs being more expensive because of the quality which meant only the rich could afford them.
The first light bulb was very expensive it was 23 dollars because the carbon filament was four times more than the other ones which were tested. After one full year of testing the different products he succesfuly tested the light bulb that lasted thirteen and one half hours.
The operating of a light bulb is quite straightforward. An electric current is run through a thin filament which then causes the bulb to get hot. Eventually it gets so hot a small light starts to grow in it and then it produces light. The bulb of the light bulb is usually made out of a strong type of glass. Before they decided to test carbon and platnium before finally returning to carbon filament.
The impact of light bulbs is that people all over the world have access to light this helps in many ways. Since they have been invented they have steadily progressed into a sleek modern version of light bulbs that come in many shapes and sizes. Light bulbs can be found everywhere in houses, shops, and many more places The final result is that everyone has them somewhere in their house and probably couldn’t live without them.
People are now absolutely dependent on lights that when they break we get them fixed straight away as we desperately need them in our life. The lights are used to see things especially at night when you are out late or you’re working late you can turn on big lights or little lamps. Because they do not need to rely on sunlight or candles anymore. Now we can live a more safe life without second guessing leaving the candle by itself.
