First of all, the light bulb on the chandelier should be removed with a ladder. When removing the light bulb, generally, just rotate the light bulb counterclockwise, and the light bulb will be released. First, you need to open the lampshade, then take out the light bulb inside and put on a new one. The whole operation process is very simple, just do it yourself. If your chandelier is high, be sure to find a ladder to climb and replace it.
