The illuminated golf balls get their glow from an impregnated UV-activated pigment. It’s triggered by a UV-flashlight that gets the balls glowing in just a few seconds. And the balls have been tested to drive 400 yards, so there’s no sacrifice to their performance.

The glowing effect lasts for around 15 minutes, and the pigment won’t wear off over time. Corky’s years of hard work makes it easy for golfers to keep an eye on the ball when squeezing in an extra-early (or late) round.
