Using this pendant light is simple. First, have a licensed electrician install it following the instructions in the box. Once installed, connect it to a 220 - 240V power source. Remember, it's for indoor use only, so don't place it outdoors. The globe is not included, so you'll need to buy one that fits the E27 lamp holder. The maximum wattage for the bulb is 72W. To maintain it, simply wipe the glass surface gently with a soft, dry cloth. If there are any issues within a year, you can get a replacement under the warranty.
