Using this pendant light is easy. First, find a suitable indoor spot for it. Make sure a licensed electrician installs it following the instructions in the box. Once installed, you can screw in an E27 bulb (max 72W) of your choice. Remember, the globe isn't included, so you'll need to get one separately. For maintenance, just use a dry cloth to wipe the powder-coated iron body regularly. Keep it away from water as it's for indoor use only. If you have any issues within the 1-year warranty period, you can get a replacement.
