The plastic balls each have a darker place, which is probably caused by a different thickness of the material in the production unfortunately at the top. The illumination is thus not uniform.
I have taken into account the advice of reviewers and three different wattages used in the LED light sources: 8W for large, 5.5W for medium and 4W for the small ball. Thus, the three a roughly uniform light pattern.
Positive is the right long rubber cord (5m). This is connected to a radio-controlled external socket, the three balls are an attractive eye-catcher in the garden.
