Using your Wonderwall table lamp is a breeze. First, make sure you have a 40 Watt A19 incandescent bulb (sold separately). Simply screw it into the lamp. To turn the light on and off, use the in - line rotary switch. You can also adjust the brightness if you have a compatible dimmer (not included). Place the lamp on any table or nightstand where you need some extra light and enjoy its modern look. As for maintenance, use a glass cleaner and a soft towel to keep the tinted glass shade and steel frame looking great. Avoid using abrasive cleaners as they might damage the powder - coated and vacuum - plated finish. And remember, the lamp is not stackable and its height cannot be adjusted, so find a stable and suitable spot for it.
