I have had the sebson gekauft.Sie lamps for the living room lamp of my parents previously "normal" candle bulbs with 40W in the lamp can be dimmed on a normal phase dimmer. The operation of the LED light source is also possible on this dimmer, as long as the minimum load of the dimmer is not fallen below. The light of sebson lamps is very pleasant and not "cold" to the light color. The dimming of the light source is the same size as the range of "normal" bulbs. The flickering LED bulbs and humming not when they are dimmed. My parents are very happy and they have already bought more sebson lamps.
