Using this pendant light is simple. First, make sure to hire a licensed electrician to install it as the installation can be dangerous without proper knowledge. You'll find an installation instructions sheet in the product box to guide the electrician. Since the globe is not included, you can choose the one that suits your style and meets the 72 - watt maximum requirement of the E27 lamp holder. This light is only for indoor use, so don't place it outside. As for maintenance, you can gently dust the iron shade with a soft cloth regularly. If you encounter any issues within a year, you're covered by the replacement warranty.
