The standard issue for military personnel worldwide, these ChemLights provide strong, reliable, 360-degree illumination for up to 12 hours. The ChemLight is so bright that it can be seen from up to a mile away – so you’ll have no trouble lighting up small rooms, hallways, trails and camps with just a single light stick. The ChemLight is waterproof, non-toxic and non-flammable. The light stick has a hook and slide opening on the top that ensures the light source stays securely in place whether you’re hanging them, attaching them or stringing them together. To activate the ChemLight, you bend it, snap it and shake it so you can instantly flood your area with functional light.
