The X300U-A is a duty-grade weapon light built around a high-output LED and a Total Internal Reflection lens to deliver a 1000-lumen beam suited for handgun or carbine mounting. The aluminum body is sealed against dust and moisture and finished in tan Mil-Spec hardcoat anodizing for surface durability.

Controls consist of ambidextrous paddles providing momentary or constant activation. The rail interface uses SureFire’s universal clamp designed for Mil-Spec 1913 rails and most full-size handgun rails, securing the light without permanent modification to the host. Power is supplied by two CR123A cells accessed through the front for straightforward servicing. No original packaging or accessories included.
