A light bulb is an electric device that produces light when an electric current passes through a filament or a gas-filled chamber. It is a common household item that is used to illuminate homes, offices, and public spaces. There are many different types of light bulbs, including incandescent, fluorescent, and LED bulbs, each with their own advantages and disadvantages. Light bulbs have revolutionized the way we live and work, enabling us to stay up late at night, read in the dark, and work indoors even when the sun is not shining. While they are relatively inexpensive and easy to use, light bulbs also consume energy and contribute to global warming, which has led to a shift towards more energy-efficient lighting solutions in recent years.
