Recessed light and can light
Can light and recessed light typically refer to the same type of lighting fixture, characterized by its installation within the ceiling or wall, with only the trim visible, creating a clean and unobtrusive lighting effect. While “can light” often denotes the cylindrical metal housing of the fixture, “recessed light” emphasizes the installation method. These terms are more commonly used in the United States. In other parts of the world, particularly in Asia, the fixture might be referred to as a “downlight.” In countries like China, Indonesia, and some other Southeast Asian nations, “downlight” is a commonly used term to describe this type of lighting fixture.
