Using your Jamison Modern Steel Task Lamp is a breeze. First, assemble it as an adult with the provided tools. Once assembled, place it on a modern desk or bedside table. You can swivel the lamp to direct light where you need it. To turn the light on and off or adjust its brightness, use the in - line rotary switch. Remember, the lamp is dimmable, but you'll need to buy a dimmer separately. When it comes to maintenance, use warm water and mild soap with a soft towel to keep it clean. Since it uses a 40 - watt G50 incandescent bulb, make sure to replace it with the same type when it burns out. Also, note that the lamp is not stackable and its height is not adjustable.
