There are many differences between traditional lighting and LED lighting. One of the most important ones is that the traditional lightings produce visible light with the help of filaments or gas, while the LED lights are chips that use diodes to illuminate. LED lights also do not heat up and they give off far more light per unit of electricity than any other traditional lighting source. They are therefore extremely efficient and durable.
