Excellent light that fits in Leatherman pouch

I purchased this light at REI, hoping it would fit into my Leatherman‘s case. It fit perfectly, but I was upset because it kept turning on and running out of juice. Major user error. After reading the manual, I understood that the light could be locked. This is the perfect Leatherman accompaniment.

Glad you found the instructions for the lock-out feature to keep it from turning on in the leatherman!

Great little light

Perfect keychain light. Bright light in a little package.

greg allen

Robert Thompson
Handy Keychain Light

The E05R is loaded with user friendly features at a reasonable price. It is a handy device in an unobtrusive package. Opt for bright when it's needed or step it down when a little light will do to extend the charge.


This Fenix light is very impressive. Live the size, settings and features. My only concern is that the on/off switch goes on when rolling around in the pocket. Still, a great light!
