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, screw in an E27 bulb (up to 40W) of your choice. When using, avoid overloading the bulb with more than 40W to prevent damage. For maintenance, gently dust the powder - coated iron body with a soft cloth regularly. Keep the fabric suspension cable away from sharp objects to avoid tearing. Remember, it comes with a 1 - year replacement warranty, so if you encounter any issues, contact us for a replacement.
