Using these PESINI pendant lights is easy. First, have a licensed electrician install them following the instructions in the box. Once installed, simply connect them to a 220 - 240V power source. Remember, the light globe isn't included, so you'll need to buy one that fits the E27 lamp holder. These lights are for indoor use only, so don't place them outside. To keep them looking good, dust the glass and iron parts regularly with a soft cloth. If any part breaks within a year, you can get a replacement under the warranty.
