However, I could here no star, despite the good price awarded for the following reasons:
The cover feels like a plastic wrap. Very Thin. It is made of PC. When opening the packaging it equals broke me. PC in white swallows much light. We have only a transmittance of about 30%.
The transfer of 6W, an indication of 480lm is already very optimistic. These are 80lm / w. This is achieved with efficient power supplies and a clear PC dome or take materials which have a higher translucency.
When measured with a photogoniometer a brightness of 213lm came out everything. This corresponds to a maximum of a 17-18W incandescent lamp.
Since it is almost cheated. Lumen information are often wrong, intentionally, no one can measure it;) Even with the major manufacturers.
The lamp has no authorization. This means that the certificate of conformity with the CE standards is common as well as in Europe, signed by the manufacturer only has this can be (and so on ... VDE TUV GS.) Demonstrate that not by independent institutes.
The lamp was conceived and built by any Chinese.
Electromagnetic Compatibility I have not checked, but a glance at the board gives the impression that it is close to the maximum noise radiation. In doubt for the accused.
I find the lamp scrap and absolute waste of resources. Since I'd rather screw for 8 euros a ship fittings with compact fluorescent lamp on the ceiling.
Conclusion: For 50-70 euros you get very much better lights where you have a lot more fun.
