The Night Eyes White LED 250 yd Gun Light is similar to the popular F6 gun light except it is 40% brighter! Shoot predators at distances over 250 yards with an average 40mm objective scope and this bright LED gun light. This distance could vary depending on the moon phase, quality of scope, environmental conditions and a hunter’s eyesight. There is no focusing or adjusting needed, whether your target is 20 feet or 250 yards just turn the light on and shoot. It has an attachable halo shield to help keep unwanted light from reflecting off the gun and reflecting back into the scope.
