These pendant lights are super easy to use. First, make sure to get a licensed electrician to install them as they are electrical products. They work with a 220 - 240V input voltage, so check your home's power supply. The globe is not included, so you can choose the one that fits your style. When using, don't exceed the maximum 72W for the 1xE27 lamp holder. Since they are for indoor use only, don't put them outside. To keep them looking great, clean the glass gently with a soft, dry cloth. If you have any issues within a year, you'll get a replacement as per the warranty.
