Using your Larzen Table Lamp is easy. First, assemble the lamp following the included instructions. Then, screw in the provided LED A19 9W bulb into the E26 screw terminal. You can turn the lamp on and off using the rotary switch. Place the lamp in your desired location to add a touch of elegance to your decor. When it comes to maintenance, always remember to disconnect the power source before cleaning the lamp shade or fixture. Wipe it with a soft, dry cloth. Avoid using chemicals and household cleaners as they may damage the finish. Keep the lamp away from heat sources and direct sunlight to maintain its appearance. If you need to replace the bulb, make sure to use a bulb with the appropriate wattage (max 'A' 100W, CFL 23W, or LED 12W). Enjoy your beautiful Larzen Table Lamp!
