Light fixtures are devices that hold and protect light bulbs while providing illumination to a space. They come in various styles, shapes, and sizes, including ceiling lights, wall sconces, and table lamps. Light fixtures can be designed for specific purposes, such as task lighting for reading or ambient lighting for creating a cozy atmosphere. Most light fixtures require a compatible light bulb, which can vary in type, such as LED, incandescent, or fluorescent. Additionally, fixtures may include features like dimmers or smart technology, allowing users to control brightness and energy efficiency. Proper installation and maintenance are essential for optimal performance and safety.
