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

I've been using these for years, I use these and bigger Calum lights for all sorts of things, get creative, activate the green and clip it, rub it all over your body and run around. Like the Hulk, imagine being exposed to toxic waste at night. Use for outdoor recreation, use indoor for emergencies or for fun. A small stick is good for marking the trail at night, large sticks eliminate a large dark area, I generally find green best for lighting purposes and the glow time, I often go into the woods with friends and to mark our trails We nail or tie them to trees to find a safe way back. Their large green and white canes are clearly visible from 500 meters away. We sometimes use them for night fishing with our gear to attract fish when that is of course allowed. I typically get 12 hours of bright light, which means you can clearly light a regular bedroom or office in your home during that time, they slowly dim and around 18 hours they're pretty dark. I have hundreds of these - the durability is forever, I have 25 year olds that I use and they work just like new ones.
