Of course, no one should truly expect this ball to be made for an organized league game since its primary selling point is that it glows in the dark. This soccer ball features two red LED lights that are powered by the same kinds of batteries used for watches. Even better, the batteries themselves are easy to change out and even have a specialized tool to assist in doing so. To prevent the batteries from running out too quickly, the ball is kick-activated and stays lit for 40 seconds.
Size 5 is the official size for professional matches. Therefore, this ball is only available in this size. Do not use this soccer ball on concreted areas. Its unique rubber uses Puma Airlock Valve Technology (PAL) in order to facilitate proper airlock technology. This ball features Perimeter Balance Technology (PBT) which enables it to maintain impressive flight characteristics. https://www.youtube.com/watch?v=j2Xn84L3Kcs
