Comments: This compact Nitecore T4K comes of a perfect size to be easily fitted onto a key chain or inside your pocket for a very discreet on the go carry.  With four high powered LED, it will definitely surprise you with one of the brightest outputs available in a flashlight of this size.  It is as easy to operate with no complex UI or awkwardly placed button but simply a power button for on and off, and a mode button to cycle through brightness settings.
