Primary I had bought this ceiling light as a means light for my living room. Unfortunately, the light does not work on triac dimmer, because the basic current of the triac the built LED keeps on permanent lights .. (At regular dimmer they should work - anderenfälls you could have a residual current consumer pre soldered) Now I have it hung in the guest bathroom, in the light projected a very pleasant cold white light in the center of the room. At the upper rim of the luminaire, a white corona is projected on the ceiling. Personally, I find the light in white Aluminiumgeäuse beautiful and she would buy me back.
