The History of the Light Bulb
äžçŽ
The light bulb is one of the most important inventions in history. Before it was invented, people used candles and oil lamps for light. In the early 1800s, some scientists began working on electric light. However, their bulbs did not last long. In 1879, Thomas Edison made a light bulb that could stay on for many hours. His invention changed the world. People could work and read even at night. Over time, light bulbs became cheaper and more efficient. Today, we use LED lights that save energy and last longer. Thanks to the light bulb, our lives are brighter and easier.
