The processing of the product looks quite cheap at first glance ... it probably is also. But for the relatively low price, it is perfectly fine. The light output is really very good, you can hardly look. The light, however, more likely than cool white warm white. I have the lights installed in the basement and in the courtyard lamp and I believe that it is all in good stead there.
All in all solid lamps for a great price. For living rooms rather not recommendable.
