Using this pendant light is easy. First, make sure you have a licensed electrician install it following the instructions in the box. Once installed, you can use any E27 globe with a maximum wattage of 72W (globe not included). This light is for indoor use only, so don't place it outside. To keep it looking great, wipe it gently with a soft, dry cloth regularly. If there are any issues within the first year, you'll get a replacement under the warranty. Just remember, don't be fooled by similar but inferior products from other suppliers.
