Why do we need the light bulb?

The light bulb is essential for providing artificial illumination, enabling us to extend productive hours beyond daylight. It enhances safety and visibility in homes, workplaces, and public spaces, reducing the risk of accidents. Additionally, light bulbs significantly contribute to our quality of life by allowing us to engage in various activities, such as reading and socializing, after dark. Overall, they play a crucial role in modern living and economic activities.
