Silver LED Office Floor Lamp with Rotary Dimmer and Up-and-Down Light The LED floor lamp provides optimal lighting conditions, because this radiates its luminosity not only downwards, but also upwards. The floor lamp is switchable and dimmable (from 900 to 8,800 lumens) via the rotary dimmer, so that an ideal illumination for the workplace can be achieved. A dimmer is also useful for light sensitivity, as it can be used to adjust the brightness as desired. The light output is uniform and ensures good concentration and work performance, whether in the home office or in other office spaces.
