SureFire X300U overview

  • 1Description

This updated version of SureFire's black X300U-B Ultra LED Weaponlight features a redesigned ambidextrous switch that is wider and shorter than the previous model to be more comfortable and easier to use. The output is upgraded to 600-lumens, and the factory-focused Total Internal Reflection (TIR) lens produces a smooth beam free of holes or hot-spots with a tight center cone of bright light with a generous spill.

Designed for pistols and long-guns the X300 Ultra easily mounts on any Picatinny/Weaver rail, and its push/toggle switch is accessible from both sides to enable fast and intuitive access to the momentary and constant-on modes. The lightweight aluminum housing is anodized to make it corrosion and abrasion-resistant, and gasket sealed for weatherproof performance. Powered by two included CR123 batteries, the X300 offers up to 90 minutes of constant runtime.

    SureFire X300U reviews

    X300U-B Ultra LED Weaponlight v2 (Black) is rated 4.9 out of 5 by 11.
    Rated 5 out of 5 by from Excellent I bought this as an upgrade from a TLR-1s. This X300U-B model is newer and utilizes the sturdier all-metal screw mount from the X400 series. In comparison to the TLR-1s, the Surefire is brighter, the switches make it much less likely to have a light ND, fit and finish is much better, usable beam spill is wider, throw is farther, and the Surefire warranty can't be beat. The Streamlight has a better battery latch and is probably about 90% of what this Surefire is on a pistol. Don't put one of these on a rifle. This style of battery latch is known to be somewhat fragile after you accidentally bang it against enough doorframes. At ranges of less than 3 yards (i.e. cramped indoor spaces) the Surefire is less than ideal, however it's absolutely phenomenal at any further distance, up to about 100 yards. Get one if most of your targets are further than arm's length. tl;dr it's a great quality pistol light. I have no regrets with mine.

    Rated 5 out of 5 by from I would buy again. Fast no-hassle delivery, factory-fresh product.This is an awesome light, truly blinding and very easy to install and use. Simple intuitive press-in for momentary-on & press-down for constant-on. Heavier & 1 longer than my usual Streamlight TLR-4, & without the 4's laser, but sturdy & solid. Does protrude beyond muzzle of full-size S&W M&P (by1.2,) & Glock17, but not of G34/35.Comes with fresh Surefire batteries. Completely satisfied with B&H and with this light.

    Rated 5 out of 5 by from THE BEST FLASHLIGHT EVER This is my first Surefire and I have to say it is absolutely incredible. It functions flawlessly, is insanely bright, and is rock solid. I currently have mine on an HK VP9 9mm and my friend has one on his CZ Scorpion EVO SBR and they work great. I especially like the temporary on and off switches and the fact that it is 600 lumens. It is an excellent light for shooting at night, searching, or completely blinding a potential threat. If you are in the market for a weapon light (especially for a pistol or SBR) look no further. This Surefire dominates every other small light from every other brand I have seen. Whether it be lumens, durability, warranty, or functionality this light does it all at top performance levels. Overall I would not hesitate to buy another one, it is by far the best small weapon mountable light I have ever seen/used to date. DO not hesitate to buy (especially for the incredible price it is being offered for here).

    Rated 5 out of 5 by from A perfect addition. My buddy let me use his Glock 19 with the SureFire X300 U-B and I was sold the first time I used it. This is a great product and must have for anyone using their weapon for home and personal defense. Do buy it from B&H, they're prices are competitive and processing time to shipping is excellent.

    Rated 4 out of 5 by from Awesome Weapon Light I can swiftly mount this to my Sig P226 and then swap it over to my Mossberg 500 just as swiftly. It's very bright and the switch is very easy to operate. The only thing I would change about this light is the battery option - I'd love to have a more normal battery option, but it is what it is!

    Rated 5 out of 5 by from perfect, texas, game/wildlife light gives you the jump on those jumping you, wild hog, large owls, bob cats, and most night time predators, when they get to close just blind the hell out of them, great for camping, trail etc. great for blinding animals and running them of in stead of having to shoot, after all its their home to.

    Rated 5 out of 5 by from Weaponlight-Duty I have used Surefire products for duty for the last five (5) years as a police officer. This product will be used on a compact weapon as I transition to undercover criminal investigations. I would trust my life to this light and BH Photo always has the best service and price!!
