Can not understand the previous speaker. In the description is clear, that the cable is just 1 meter long and one required a powerbank with 5V / 2A output. Who pays attention can not do much wrong with the product. Only the plastic reflector could be replaced by metal. (Have a similar lamp on eBay purchases, but with 3 LEDs and since the metal reflector. Is) still the lamp fulfills its purpose and is very bright.
Unfortunately, the lamp will be slightly warm, but this does not really bother. When I screwed it I could find to my surprise that the LED chip is connected to thermal compound with the aluminum case and thus emits the generated heat via the housing.
The dispatch has indeed lasted over a week, because the lamp probably does not come from Germany in the review is about is the product, not the shipping.
