Multifunctional Jona floor lamp with infinitely variable rotary dimmers The LED-operated Jona floor lamp is a real all-rounder. This is a combination of an uplighter and a reading lamp, which presents itself in a filigree and timeless design. With 2,900 K, the floor lamp produces a warm white light that is just as suitable for general room lighting as for regular reading activities. The lights of the reading lamp and the ceiling washer can be regulated continuously and independently of each other.
