The primary use of a light bulb is to provide illumination. Light bulbs convert electrical energy into visible light, significantly enhancing visibility in homes, workplaces, and public spaces. Over the years, various types of light bulbs have been developed, including incandescent, fluorescent, LED, and halogen bulbs, each offering different benefits in terms of energy efficiency, brightness, and longevity. The invention of the light bulb revolutionized society by extending productive hours into the night, improving safety, and enhancing our daily routines. Today, energy-efficient options like LEDs are becoming increasingly popular as we seek sustainable lighting solutions.
