Review on 🔦 Cyalume ChemLight Military Chemical Sticks: Top Occupational Health & Safety Products for Facility Safety by Tony Reid

Cute little chemical lantern. They are good for marking things in the dark. Sometimes they are used to illuminate gun sights, but I use them to illuminate dog collars on night walks. I attached a piece of rubber tubing to her collar and stuck a flashlight into the end of the tubing. I can see him about 80 meters away. They last at least 4 hours.
