Using this lamp is easy. First, plug it into a 120 - volt outlet. You can adjust the light brightness using the full - range dimmer on the shade. Just turn it clockwise to brighten and counter - clockwise to dim. When it comes to safety, remember that this lamp can expose you to lead, so keep it out of reach of children and wash your hands after handling. For maintenance, use a dry cloth to wipe the metal shade and base regularly to keep them looking shiny. If the bulb burns out, simply replace the 50W GU10 halogen bulb with a new one.
