An LED downlight is a type of lighting fixture that is installed in ceilings to provide focused illumination. These lights are designed to direct light downward, making them ideal for areas like kitchens, living rooms, and hallways. They are energy-efficient, using less electricity than traditional incandescent bulbs, and have a longer lifespan, which reduces the need for frequent replacements. LED downlights come in various styles, sizes, and color temperatures, allowing for customization in both residential and commercial spaces. They can be used for general lighting or to highlight specific areas, enhancing the overall ambiance of a room while minimizing energy costs.
