Using this table lamp is easy. First, find a stable surface for it, like a side table or nightstand. Make sure the surface can support its weight of 16 units. Then, plug it into a 110 - volt outlet. The 3 - way socket allows you to adjust the light brightness according to your needs. Just insert a single TYPE A bulb with a wattage of 150W. As for maintenance, use a soft, dry cloth to clean the marble base and brass accents regularly to keep them looking shiny. For the linen shade, if it gets dirty, you can use a gentle vacuum cleaner to remove dust. Remember, this product contains nickel, so avoid direct contact with your skin for long periods.
