This term refers to a specific type of lighting fixture, often circular, designed to be installed within a ceiling or wall, with a diameter of approximately four inches. These lighting solutions are commonly available for purchase at a large home improvement retailer. These fixtures provide a focused beam of light, useful for highlighting specific areas or objects within a room.
The appeal of these lighting options stems from their space-saving design, energy efficiency (when used with LED bulbs), and versatility in application. They offer a sleek, modern aesthetic and can be used in various settings, from kitchens and living rooms to hallways and bathrooms. Their historical context lies in the evolution of lighting technology, moving from traditional, exposed fixtures to more integrated and discreet solutions, maximizing both illumination and visual appeal.
