Lights up after every stroke Find your ball even when it gets dark Comes in mixed colors. With luminous golf balls you don't have to give up an early morning round at dawn or interrupt that perfect round of golf when dusk falls. When you hit, the LED diode in the ball's core is activated and lights up the ball, which continues to glow for 8 minutes. This gives you plenty of time to get to the ball even after a really long drive. After 8 minutes, the light goes out, but if you're quick, there's no need to panic - the ball's timer is reactivated after every stroke so that the ball never goes out on the green. The ball is designed by golfers for golfers with a focus on preserving the feeling of the game with high-performance aerodynamics and the feel you expect from a quality ball.
