One of the most widely-issued weapon lights in special operations and law enforcement, The Surefire X300U is widely known for its reliability. It's practically indestructible, and one of the brightest lights on the market. SureFire recently upgrade to the light making it put out 1000 lumens for 1.25 hours on two CR123A batteries.
This light can be used at distance very nicely due to its tight beam and a focused center and spill on the edges.
This light provides you with the ability to simply press the switch on either side for momentary-on activation or flip up or down for constant-on activation. It is also equipped with ambidextrous switches which are now wider and shorter from the previous models making it much easier to activate.
