The Klarus X5 is one of the first lights on the market to feature a AAAA (that is four As) and still have a whole lot of output. The X5 achieves an incredible 76 lumens in its very, very small form factor by using a special circuit to power the CREE XP-E R2 LED. Even more impressive, the four output levels are digitally regulated and have no PWM that can cause flickering.
