The 6" lightstick is a portable and cost-efficient source of light. Each lightstick is a pliable plastic tube filled with two non-toxic chemical solutions, one held separate in a floating ampule to prevent activation until required. To activate, simply bend the tube and shake. This breaks the ampule and mixes the chemicals. A bright light is released via chemi-luminescense, a chemical reaction converting energy to light without heat, flame, or sparks. No batteries or bulbs are required. These lightsticks are suitable for a wide range of applications in combat, training and outdoor activity.
