Light bulbs entered people’s lives in the 1880s. Tungsten filament lightbulbs have been around for about 100 years. Fluorescent lamps were invented in the 1920s. These two mainstays dominated most lighting applications for most of the twentieth century.
Electric light became a part of our lives around 1880 as Thomas Edison began illuminating parts of New York City. For more than 100 years, the basic operating principle of light bulbs remained the same. For the most part, we used the incandescent bulbs that Edison pioneered. Of course, there were fluorescent bulbs as well, but most of our lamps used the familiar incandescent in various configurations.
