Multifunctional Jona floor lamp with stepless rotary dimmers The LED-powered Jona floor lamp is a real all-rounder. This is a combination of an uplighter and a reading lamp with a filigree and timeless design. At 2,900 K, the floor lamp produces a warm white light that is just as suitable for general room lighting as it is for regular reading activities. The lights of the reading lamp and the uplighter can be adjusted continuously and independently of each other.
