12 volt dc neon LED light, you need 12v 2 amp dc adaptor to run the neon LED light. No adaptor in package, only neon light 5 meter length. LED lights, or light emitting diodes, are a highly efficient and versatile form of lighting used in a variety of applications. Unlike traditional incandescent bulbs, LED lights produce light through the movement of electrons in a semiconductor material, resulting in significantly lower energy consumption and longer lifespan. They are available in a wide range of colors and can be designed to emit light in specific patterns, making them ideal for everything from residential lighting to industrial and commercial use. Leds are also known for their durability, as they are resistant to shocks and vibrations, and they emit very little heat, reducing the risk of fire. Additionally, LED lights are environmentally friendly, as they contain no harmful substances like mercury and are fully recyclable.
