Review on Cyalume ChemLight Military Chemical Duration by David Skyline

I usually buy the blue Cyalume Snaplight Light Sticks but I bought them at a good discount. Now I understand why. The description states a shelf life of 4 years from the date of manufacture. They have already expired three years after this date and will not expire until one year later. They also only burn for 10 minutes before extinguishing. Such a disappointment. I will never order again. Even at a good price.
