Using this pendant light is easy. First, have a licensed electrician install it following the instructions in the box. Once installed, you can screw in an E27 bulb (up to 72W) of your choice. Since it's for indoor use only, don't place it outside. To maintain it, simply wipe the aluminium surface with a soft, dry cloth regularly. Remember, this product comes with a 1-year replacement warranty, so if there are any issues, contact us right away.
