Industrial Versus Military Grade
on August 31, 2011
These simply work. Used them extensively in the military.
One thing I will add to your purchase consideration: the Cyalume SnapLight "Industrial" Grade Chemical Light Sticks lights are chemically very similar to the "Military Grade", but with a longer shelf-life. The "military grade" lights are formulated per DoD specification, and as such cannot take advantage of newer formulations.
In short: if you are buying the "Military Grade" lights because you think they are better somehow, they are not. They are the same brightness. As a matter of fact, according to the manufacturer the military versions have one year less shelf life (4 versus 5 years for the industrial series). The higher price reflects the custom (older) formulation that the DoD specifies.
Source for this info: Cyalume Corporation.
So unless you are required to buy an NSN product, do yourself a favor and pay less for a longer shelf-life and get the industrial version of this product.
Hope this helps.
