Delivered bare wire! Yes you will say, it was in the picture, but I had not seen it ... well after all I understand is to pass the wire through the wall.
I installed a decision to test, before attaching it: the power is correct, the light is pretty cool white.
For a small terrace, I installed 2 spots to 3m high, and it's perfect. It sheds light on 20m² (2 spots).
