The quality of the LED light source is correct. When unpacking it shows the good workmanship and the solid construction. Live in the hands, the design looks again better than in the photos. Quite clearly, this is a matter of taste! I love the unusual anyway and am impressed!
But now the most important, the light output!
At first I was really surprised at how light the "relatively" few LEDs and what is in matters as overall performance in space. I've already installed several LED lamps in the house and can therefore quite well recognize differences. Clearly, the light output is very good. Comparable 75 watts can be achieved in any case. The electricity consumption is measured 10.5 watts.
The lamp is in operation, no noise.
The light color is warm white. The light is pleasant and has no yellow or greenish on. With specified 3000K color is slightly higher than halogen, speak a little cooler. In my opinion, however, the perfect modern 3000K LED color and therefore also completely living room Suitable!
For durability I can not give any indication. The lamp has been in operation for only a few days. Should adjust a defect, I will report my update.
