Using this pendant light is easy. First, make sure you have a licensed electrician install it according to the instructions in the box. Once installed, screw in an E27 bulb (max 72W) as the globe is not included. Since it's for indoor use only, don't place it outdoors. When it comes to maintenance, you can gently dust the glass and iron parts regularly. If there are any issues within the first year, you're covered by the replacement warranty. Just avoid using abrasive cleaners that could damage the glass or iron finish.
