Great for edc - SureFire G2X LE Dual-Output LED Flashlight, 600 Lumens

I love to walk my big dog at night, so I always carry a flashlight - it is part of my EDC. With the dual output, I can either light-up the whole street on High or toggle to Low without cycling through a lot of other worthless modes, such as strobe or SOS. I also like the fact that there are no pocket clip. I carry this light in my left pocket so I can have my right hand free for controlling the dog or going for my gun.
