In the 1850s, people primarily lit their homes with oil lamps or candles. Oil lamps burned various types of oils, such as kerosene or whale oil, which provided a source of light. Candles were made from tallow or beeswax and were often used as a more portable lighting option.
The light bulb had a major impact on American lives. For one thing, electric light replaced dangerous oil lamps and candles. For another, it allowed people to stay up later, since they could turn on bright artificial light to work by.
Not all African Americans were slaves. Many were free African Americans while others were so light in their skin color so they could pass as a white. Some free African Americans owned slaves themselves.
Honestly?! Common sense, if light bulbs were not invented then we would still carry candles with us for light plus no one has to go street to street lighting lamps they're all automatic now.
It's funny, you are like the "Americans" you are trying to insult. You read patented as meaning invented. Edison created the first commercially viable light bulb, he didn't invent the technology.

Most light in America is provided by electric lights not oil lamps. However there are two types of oil lamps still sometimes used (mainly for decorative purposes): chimney lamps and tiki torches. Chimney lamps use a highly purified odorless kerosene type oil. Tiki torches use a nonspecific petroleum distillate oil.
