This football lamp is actually a football with built-in lamp! It is 30g heavier than normal football, there’s the kinetic energy recovery unit in addition to the internal bladder, which may convert the energy playing football into electric energy for illumination of lamp. Approximately 30 minutes kicking is enough to allow lamp to keep work three hours, which is considerable practical.
