Using this pendant light is easy. First, make sure you have a licensed electrician install it according to the instructions in the box. Since the globes aren't included, you can choose the ones that suit your needs and style. Just screw them into the E27 lamp holders. Remember, this light is for indoor use only, so don't place it outside. For maintenance, simply turn off the power and gently clean the opal glass and iron parts with a soft, dry cloth. If you encounter any issues within the 1-year warranty period, you can get a replacement.
