Review on Cyalume 9-86000PF Mini ChemLight: Ultra-Bright Military Grade Chemical Light Sticks (4 Hour Duration) - Unmatched Illumination by Ross Decoteau

Cute little Apothecary Lanterns. 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.
