Using your Twilight Table Lamp is easy. Just plug it into a 110 - volt outlet and turn on the 3 - way socket to light up your space. Remember, this lamp has only one TYPE A bulb, so if it burns out, replace it with a new 150W TYPE A bulb. When moving the lamp, be careful as it weighs 8 units. To keep it looking great, dust the ceramic base with a soft, dry cloth regularly. Avoid using harsh chemicals on the base or the light gray linen shade. Also, since this product contains nickel which can be harmful, keep it out of reach of small children and pets. If you live in California, be aware of the cancer - causing risk associated with nickel as per CA Prop 65.
