Using your Demra Table Lamp is a breeze. First, make sure the lamp is placed on a stable surface. Then, plug the cord into a power outlet. You can turn the lamp on or off using the ON - OFF rotary switch. When it's time to change the bulb, simply unscrew the old one and screw in a new LED A19 9W bulb with an E26 screw terminal. Here are some important notes. This lamp contains DEHP and lead, which can cause cancer, developmental, and reproductive issues, so handle it with care. For maintenance, always disconnect the power before cleaning. Use a soft, dry cloth to wipe the lamp shade and fixture. Avoid using chemicals or household cleaners as they can damage the finish. Enjoy the elegant and modern lighting this lamp brings to your home.
