The Quark series of LED flashlights, designed by 4Sevens, is the result of input from engineers and flashlight enthusiasts around the world for over 5 years. The upshot: there is no finer, more useful flashlight than a 4Sevens. Proven reliability, functional versatility, and enough illumination to challenge the sun itself - this is the flashlight, redefined.

And the Quark 123 is no exception.  With 230 max lumens out the front (OTF), the Quark 123 is exceptionally bright for a single battery flashlight.

The Quark 123 is perfect for Everyday Carry (EDC) and easily fits into a pocket.  The light is equipped with a removable bezel down clip for easy attachment to your pocket.
