With this practical duo wall dimmer you can easily dim two light sources from 0 - 100%. The dimmer works in combination with our LED lamps, but you can usually dim your own light sources with it. You can set the maximum percentage to which the lamps can be dimmed with the adjusting screw. The dimmer has an electronic fuse and is protected against overloading, short circuits and incorrect connection. In case of a malfunction, the dimmer will reset itself without any damage.
