Be sure with surefire e1b backup - SureFire Backup With MaxVision High Output LED Flashlight

I bought this back up light knowing the brand for my edc kit. There are plenty of dark places now that winter is here and this little puppy lights them right up with 2 modes the full 400 lumens is bright enough to light up a fully blackened hallway. I do wish it had other features maybe a strobe but hey size is what I bought it for and in my pocket with added wrist lanyard I don’t worry about losing her. Best light I own.
