Good LED floodlight, but .......

... To the article that came very well packaged, no written documents were sent along. Only the naked floodlights. It therefore lacks any information about the manufacturer and the technical values ​​of the article, all safety instructions and especially reliable indications for the adjustment of the motion detector (3 mini knobs for Sensor, Time, Lux)
It helps only a try until you have found the setting because even the control range (usually have no mark) is unknown.
An inquiry to the seller because of the missing information and documents was answered quickly but unsatisfactory: there is no description by the manufacturer and you would but also create in such simple items as the setting.
Yes it works; but it takes hold and mW are prescribed in the EU and in Germany for the sale of such electrical products using a manual and safety instructions.
So far I have never experienced something like that; not the few "cents" costs for articles.
Too bad, because actually the product itself is fine.
I have the evaluation at 16.10. increased to 4 stars because the radiator still works properly and the price it really was very low.
