Surefire X300U-A Ultra LED 1,000 Lumen Weapon Light Product Info

Both the Black & Tan models are in stock and ready to ship!

The new and updated powerful and versatile X300 Ultra LED 1,000 Lumen Weapon Light features a high-performance LED that generates 1,000 lumens of stunning white light focused by a Total Internal Reflection (TIR) lens to produce a tight beam with extended reach and significant surround light for peripheral vision. The virtually indestructible and highly efficient LED on this Tactical Weapon Light from Sure Fire generates tactical-level light-more than enough to overwhelm an aggressor’s dark-adapted vision-for 1.5 hours per set of batteries. The high-strength aerospace aluminum body on the Sure-Fire 1,000 Lumens X300U-A Weapon Light is Mil-Spec hard anodized for superior toughness and is O-ring and gasket sealed to make it weatherproof. This Sure Fire Gun Light is also versatile and can be attached to a pistol or a long gun since its Rail-Lock system permits rapid attachment to and removal from either Universal or Picatinny rails. Its integral ambidextrous push/toggle switch provides one-finger operation for either momentary or constant-on operation. Optional DG grip switches are available for use with a pistol, and an XT07 tape switch permits the SureFire X300 Ultra Gun Light to be activated when attached to a long gun without altering your grip on your weapon. Available in both black and tan (FDE).

    The best keep getting better! Better throw and flood, and it kept the same footprint as the older Ultra models. Buy with confidence, and buy from BigTex!

  14. Joe

    I have ordered from Ike many times, and the experience is always great, my questions and concerns are answered quickly, and nobody ships as fast as Big Tex Outdoors.

  15. Bartosz

    Surefire is the top quality, everyone probably knows that, but customer service is top notch 🙂

  16. John

    As always Big Tex offers tbe best price, fast shipping, and awesome CS. This is my 2nd 1000 lumen X300U, and for good reason. Surefire makes the best weapon light, and I trust my life to nothing else.

    Fast shipping. Great customer service. Everything you would expect out of a surefire weapon light. Great mounting options.

  23. William (verified owner)

    Ordered on Friday, shipped on Monday! The light simply locked into my G19 like it was designed for it. This is a very simple to use and naturally operate 🔫 light. I highly recommend it. Now to buy some new holsters!

  24. Rufus Fields (verified owner)

  26. azaex55 (verified owner)

    Great light, lever latch mounts perfectly snug up to the G19X rail.

  27. Tyler (verified owner)

    Quality, durable light, and fast shipping

  28. pho3nixt3mplar (verified owner)

    Shipped super fast. And the sale Big Tex had made the light $15-30 cheaper than they are sold used! I should have gotten two.

  29. Texas_Al (verified owner)

    Bought this cheaper than anywhere else on the internet. It came in extremely fast. Big Tex Outdoors is now my primary source for firearm related items.

  30. Richard Bamberger (verified owner)

    Product is authentic and works great. Got it for roughly $50 less than anywhere else online, no one else has these on sale. Not only do these guys ship insanely fast but their customer service is excellent too and they have products I can’t find anywhere else. They have a lifetime buyer here.

  31. Robert Bodron (verified owner)

    Purchased this for use on a duty carry Glock 17 MOS. The light snaps right on and fits well. I’m not a fan of the push-forward momentary switch. I much prefer the press-down momentary switch on the streamlight pistol lights. The attachment method is a big improvement over streamlights though, but it will not interchange to some of my steel frame guns without adjustments.

  32. Bohdi O’Neil (verified owner)

    Kickass handgun light. Super tough, good throw and candela. Super fast shipping.

  33. Phill (verified owner)

    Excellent handgun light. I picked one up with I got sick of my XC1 sucking at life, and my only regret is not making the switch sooner. Far more throw and spill. Locks onto my G19.4 nice and tightly with no tools.

    As always with big tex, shipping was super fast.

  34. Cory (verified owner)

    The x300u is the gold standard of pistol lights

  35. Jordan Buchanan (verified owner)

    Fantastic light, great shipping times. No better flashlight if mounting to a Glock frame. Perfect length for a Glock 34. I look forward to purchasing here again soon.

  36. kctaylor89 (verified owner)

    Shipped fast and intact, fits well on my 509. No complaints, would definitely order from here again.

  37. Bradley Rayfield (verified owner)

    Ordered one for my glock 19, awesome product. But the customer service is top notch. Big Tex is now my go to site.

  38. jorgeojeda2000 (verified owner)

    Fantastic Light, got it on black friday for the best deal around! Showed up on the following Monday!

  39. Fraz (verified owner)

    Light is solid. A model is great for quick off and on or switching between different guns. A little expensive vs TLR1-HL which is probably 85% as good for around 50% cost. Got it at a great price here so no complaints.

  40. John (verified owner)

    This is the light to beat for handgun weapon lights. Currently there is no equal.

  41. Benjamin Duffield Magee (verified owner)

    Like others have said; get it. This light is awesome. Surefire is the best and so is Big Tex. I am very happy I purchased this light.
