Weapon Lights for SHTF Guns

 Weapon Lights for SHTF Survival Rifle Setups"--Ammo Land. Some tips on selecting a good light: 

1. High lumens v. high candela. 
2. Battery life and power options.
3. Mounts and activation switches.
4. IR capability (if running night vision).
5. And some of his recommendations as to specific lights.
   

 I would echo a few of the comments, however, that for a survival setup, you need a light that can accept and use rechargeable batteries that can be charged off a portable solar system.
