LED strip lights, also known as LED tape lights or LED ribbon lights, are flexible circuit boards populated with LEDs (light-emitting diodes) that are typically mounted on an adhesive backing. They come in various lengths, colors, and densities of LEDs per meter. LED strip lights are versatile and commonly used for decorative lighting, accent lighting, under-cabinet lighting, and many other applications both indoors and outdoors. They are popular due to their flexibility, ease of installation, energy efficiency, and ability to create dynamic lighting effects.
