The GlowV2 night golf ball glows by infusing the balls skin with an ultra high level of proprietary glow pigment. This pigment is activated by the sun or with one of our UV flashlights or our UV Glow Charger (at each tee box) The key strength of our night golf ball is the fact that it is a legitimate full compression performance golf ball that hits and feels like your favorite “daytime” golf ball. Unlike glow stick golf balls or LED golf balls that are hard as a rock and can break your clubs, the GlowV2 allows a golfer to feel confident that the club distances and performance they are used to during the day transfer into the night.
