The harness between the controller and the individual LEDs is as obvious all the same kind of thin and lights sheathed wires. In this Lichterkette the 5 wires are twisted and act from a distance like a single cable.
The cables are provided at the entrance to the controller with a bend protection and protect at least against rough environmental influences. But as mentioned in the item description, the controller must be installed indoors or in addition against environmental influences and probably to protect water in particular before (injection).
The power cord has a grounded plug without grounding.
The 8 different modes of the controller will press on the single button on the controller repeatedly switched through.
All modes are numbered on the housing lists - marked not as a sticker but in the case. Good thought along because this label is well if at all only after many years of use illegible and does not dissolve like a sticker after a short time.
My personal opinion on the Christmas Lights:
In contrast to the images, the chain is much brighter and emits a rather orange light.
I am absolutely satisfied with the Christmas Lights and have so far no other manufacturers have found which provides a comparable good quality of workmanship.
Even after several hours of "continuous light" mode, the lights remained absolutely cold - LED technology precisely.
