I think I'm not mistaken about the prize so here are some explanations about the luminous ball:
Thanks to a small button located under the ball, you can choose between different lighting modes, fade out, blinking or fixed. These little balls are magical! The crossfade mode gradually changes from one color to another (6 in total). You place your lumiglobe on its small base and you will have 8 hours of autonomy per charge cycle.
Ideal in children's rooms to serve as a nightlight, very pleasant in the living room.... You can take it anywhere in the house!
It is the same How it Works as the mobo light balls, except that it works with batteries..... It is a ball of about fifteen centimetres in diameter that is coloured in several colours... quite pretty! 👏
