These glow sticks are made specifically for use with night golf balls.  Their wider profile makes them fit tighter in the ball so there is less likelihood they will pop out when the ball is hit by the club.  They will last most of the night (up to 8 hours) and can be seen up to 300 yards away at night when there is less competition from other light.  They are available in 5 colors.  This item does qualify for free pickup.
