Using the Lastra Table Lamp is easy. First, find a stable spot for it in your room. Make sure the surface can support its 4.4 - pound weight. Then, screw the included LED A19 9W bulb into the E26 screw terminal base. Plug the lamp into a power outlet, and use the ON - OFF rotary switch to turn it on or off. When it comes to maintenance, always remember to disconnect the power source 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. Also, be aware that the lamp contains DEHP and lead, which can pose cancer, developmental, and reproductive health risks, so handle it with care.
