Recessed lighting refers to light fixtures that are installed into a ceiling, creating a clean and streamlined look. These fixtures are often called "can lights" or "downlights" because they are housed in cylindrical metal cans that are recessed into the ceiling. This type of lighting is popular in both residential and commercial spaces, as it provides a modern aesthetic while effectively illuminating areas without taking up visual space. One of the main advantages of recessed lighting is its versatility. It can be used for general lighting, task lighting, or accent lighting, depending on the placement and type of bulb used. Additionally, LED bulbs can be used in recessed fixtures, making them energy-efficient and long-lasting options for homeowners and businesses alike.
