Cyalume Chemlight, Military Grade Light Stick, Infrared (IR), 6-inch, 3 Hour Duration

As advertised. Fast shooting.

It's hard to rate the Chem light's didn't work. So in other words I received 10 I've opened 4 none of them worked.I'm trying to replace them???

These are for night vision applications. Can be seen with night vision goggles and other night vision apparatuses.
