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 (not included) with a maximum wattage of 72W. This light is only for indoor use, so don't try to use it outside. For maintenance, keep the iron shade clean by wiping it gently with a dry cloth. If you encounter any issues within a year, you can get a replacement as per the warranty.
