Using this pendant light is simple. First, have a licensed electrician install it following the instructions in the box. Since it's for indoor use only, don't place it outside. The light doesn't come with a globe, so you'll need to buy one that fits the E27 lamp holder (max 72W). For maintenance, you can use a dry cloth to wipe the iron cage regularly. If there are any problems within the 1 - year warranty period, you can get a replacement. Just keep in mind to avoid using it with a voltage outside the 220 - 240V range to prevent damage.
