Using this pendant light is easy. First, make sure you have a licensed electrician install it according to the instructions in the box. It's designed for indoor use only, so don't place it outdoors. Since the globe is not included, you need to buy one that fits the E27 lamp holder with a maximum power of 72W. To maintain it, simply wipe the glass and iron parts with a soft, dry cloth regularly. If there are any problems within one year, you can get a replacement. Just avoid similar low - quality products from other suppliers to ensure you have a good experience.
