LED lights are a type of lighting technology that uses light-emitting diodes (LEDs) as the source of illumination. LEDs are more energy-efficient and longer-lasting than traditional incandescent bulbs, and they produce very little heat. LED lights are available in a wide range of colors and can be used for both indoor and outdoor lighting applications. They are also becoming increasingly popular for decorative lighting, such as in holiday decorations and in accent lighting for homes and businesses.
