SureFire X300U Weapon Light


Video | What’s Included | Specs | Pictures | FAQ | Restrictions | Related Info

The SureFire X300U is one of the most widely-issued weapon lights in special operations and law enforcement units. And for good reason. It boasts an impressive track record, is nearly indestructible, and has improved with the times at a steady pace. The current X300U can put out 1000 lumens for 1.25 hours on two CR123A batteries. The beam is tight with a focused center and spill on the edges. This means the light can be used at distance very nicely. Activating the X300 Ultra is done via intuitive, ambidextrous switches—now wider and shorter for improved ergonomics—at the rear of the body. Simply press the switch on either side for momentary-on activation or flip up or down for constant-on activation. We highly recommend the X300 series of lights at T.REX ARMS.

The X300 Ultra is comprised of two models, the “A” and “B”. These signify the attachment system of the light. The A model features Surefire’s Rail-Lock system, a latch attachment. You pull down on the two levers on the side of the light and slide the X300 onto the rail system. It will then lock in place. The B model has a T-slot mounting solution that is tightened by hand, and then turned a half rotation with a flathead screwdriver, bullet casing, knife, etc.

Which attachment option should I choose?
SureFire makes the A quick latch model for polymer frame guns and the B thumb screw model for metal frame guns.
What makes the X300 ULTRA different from the X300 TURBO?
The Ultra has more lumens than the X300T (1,000 vs. 600) and more flood, but less peak beam intensity (11,300 vs. 66,000 candela) and less throw (40 vs. 150 meters). The battery life is slightly less than the TURBO (1.25 vs. 1.5 hours). We tend to opt for higher candela options like the TURBO, but it does come down to mission and preference—more flood may be the best for you.
