Using your table lamp is easy. Just plug it into a 110 - volt outlet and turn it on using the 3 - way socket. You can adjust the light according to your needs. When it comes to the bulb, use a single TYPE A bulb with a wattage of 150W. As for maintenance, gently dust the iron frame regularly to keep it looking good. For the linen shade, avoid getting it wet. If it gets dirty, you can use a soft brush to remove the dust. Also, be aware that this lamp contains nickel, which is a chemical known to cause cancer in California. So, keep it in a well - ventilated area and follow the safety advice on www.P65Warnings.ca.gov/furniture.
