Using this pendant light is simple. First, have a licensed electrician install it according to the instructions in the box. Since the globes aren't included, you'll need to buy suitable E27 globes. Only use globes with a maximum power of 72W to avoid any issues. This light is for indoor use only, so don't place it outside. For maintenance, turn off the power before cleaning. You can gently wipe the iron parts with a soft, dry cloth. If there are any problems within a year, you're covered by the replacement warranty.
