To use this pendant light, first, make sure you have a licensed electrician install it according to the instructions in the box. Since the globe isn't included, you'll need to buy one that fits the 5xE14 lamp holder (max 60W). It's for indoor use only, so don't put it outside. When it comes to maintenance, use a soft, dry cloth to clean the stainless - steel body and the chrome chain and cable. If there are any issues within the 1 - year warranty period, you can get a replacement. Be careful not to buy inferior copies from other suppliers.
