Using this pendant light is easy. First, make sure you have a licensed electrician install it according to the instructions in the box. Once installed, you can use any E27 globe (not included) with a maximum wattage of 40W. This light is only for indoor use, so don't try to use it outside. To maintain it, simply wipe the wood and glass parts gently with a soft, dry cloth. If there's any problem within one year, you can get a replacement. Just remember to avoid similar low - quality products from other suppliers.
