Cortex Compact Flashlight

In 2008, Gerber engineered innovation in lighting with Omnivore Technology, Gerber's patent pending technology for variable-battery use. It’s skillfully applied in the Cortex Compact flashlight. With its sleek design, the Cortex Compact functions as a discreet, everyday carry light for tactical professionals, and a backup light for police officers.


Running on a single Lithium CR123 battery or a single AA battery, the Cortex Compact allows the user options given whatever power source is available. When powered by a CR123, the Cortex Compact provides 125 lumens of output, enough light to momentarily blind an aggressor's night-adapted vision. The Cortex Compact also provides a strobe mode for tactical applications, and a low-output mode for navigation. Housed within machined aluminum for strength and durability, and coated black for low visual signature when not in use, this solid 4-inch, 2.1 ounce light clips neatly inside pants pockets for quick access. The Cortex Compact flashlight is built in Portland, Oregon.

5 Your Title Mountain Man - JUL 17, 2015

Best little EDC light I've owned! First I lost it in my back acreage and several days later one of my dogs found it and dropped it on our deck. It rained a couple times over that period but it still worked. Then the real test, I thought lost it once again working on my riding mower on the same piece of land, but it was actually in the pocket of my bib overalls. It was found when my wife pulled the bibs out of the dryer and they were glowing. It was the flashlight, turned on and working! This little light went through a machine wash and spin cycle, then at least forty minutes in the hot dryer. The battery was weak but after replacing it, it works like new. Without a doubt the best little flashlight I've ever owned. I put as much value on this little bugger as I do the Swiss army knife I've carried for over thirty years. If I lose it again, I'm ordering a new one immediately, worth every penny!!!
