Using your Sascha Table Lamp is easy. First, assemble it as an adult with the tools provided. Then, screw in the 40 Watt A19 incandescent bulb (sold separately). You can control the light with the in - line rotary switch, and if you want to adjust the brightness, you'll need to buy a dimmer. Place it in any room to add a touch of style, whether it's a glam living room or a boho bedroom. When it comes to maintenance, use warm water and mild soap with a soft towel to clean the lamp. Avoid stacking it on other items as it's not stackable. Also, make sure it's plugged into a 120V outlet for proper operation.
