The Omnivore Technology of this tactical light allows you to power it with either 2 AA batteries or 3 CR123 batteries. When running on CR123s it puts out an amazing 675 lumens, more than enough to overwhelm an aggressor or identify a threat. It also has a strobe mode for tactical applications and a low output mode for administrative duties. When having options is critical, and you need enough light to be successful in any tactical situation, you need the Gerber Cortex.
