      The light bulb has evolved a lot on how it is made. Check the next video

      The newest technology is called LED (a shortcut for Light Emitting Diode), and is using materials similar to the glass to create lights. That is done playing some smart tricks with the electrons living in the LED. This new light bulbs based on LEDs use only around 20% of the energy used by a standard light bulb.
