Using your 21-inch gold and white marble table lamp is easy. First, assemble the lamp following the included instructions. Attach the white fabric drum shade to the base using the threaded uno shade fitter. Plug in the 72-inch cord to a power source. Then, use the rotary socket switch to turn the lamp on and off. For best results, use an LED bulb with a maximum wattage of 60. When cleaning the lamp, gently dust the marble base with a soft, dry cloth. Avoid using abrasive cleaners or water on the marble. To clean the fabric shade, use a soft brush or a vacuum cleaner with a brush attachment. Keep the lamp away from direct sunlight and heat sources to prevent damage. And remember, this lamp is for home use only, not for commercial purposes.
