The powerful, virtually indestructible X300 Ultra WeaponLight was primarily designed for handguns but is also excellent for long guns and mounts securely to MIL-STD 1913 rail-equipped rifles via its newly enhanced T-slot mounting system. This top-selling WeaponLight features a high-performance LED that generates 600 lumens of stunning white light that’s focused by a Total Internal Reflection (TIR) lens to produce a high-intensity beam with extended range yet it provides significant surround light for peripheral vision in close quarters. The highly efficient virtually failure-proof LED generates tactical-level light—ideal for close- to long-range target identification—for 1.5 hours per set of batteries.

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. Optional DG grip switches (for handguns) and pressure-activated XT tape switches (for long guns) permit the X300 Ultra to be activated remotely.

The X300 Ultra can be securely attached to a handgun or a long gun via its new and improved T-slot mounting system. Universal and Picatinny crossbar wedges are included for simple, foolproof installation. Its high-strength aerospace aluminum body—including the mounting system—is Mil-Spec hard anodized for superior toughness and it is O-ring sealed, making it weatherproof.

FITS: The new T-slot mounting system fits most railed handguns (and rail-equipped long guns) but adapter mounts are available for some non-railed handguns—click here to view them.

    Me Likey
    September 23, 2013
    Be careful! This light is bright. I accidentally shined it in my eyes and it seared my retinas to a flakey crisp. The light is built very well. After I blinded myself, I dropped the light onto the floorboards of my truck seconds before I careened off of an embankment and came to a fiery halt. The light appears to have suffered no damage. I would recommend this light to my pals that still have their eyesight and are able to shoot.

    Fantastic weapon light!
    April 8, 2016
    Replaced a TLR-1 with this X300 ultra. I'm using it on a Glock 34 Gen4. It's a great fit! I like the mounting of the X300 Ultra B model. It's similar to the mounting of the TLR-1 with the screw type mounting. I had to crank it down a little harder than I was used to with the TLR-1. I thought I had the X300 Ultra B tight enough on the rail but after 150 rounds, the light was loose. Just had to tighten it back down a bit tighter using a dime. All in all, the light is great! SUPER bright and focused beam. I'm very happy with it!
    Bright Ease of mounting Good controls of the light
    A little pricey

    Great light
    June 20, 2015
    Perfect lightweight weapon light. Works really well mounted in the 12 o clock position(m4 flat top, no front sight post). When paired with a lower 1/3 optic and unity tactical exo, there really aren't any better options. The lower 1/3 optic allows you to see just a little bit of the x300 in the bottom of the field of view. The unity tactical exo, protects the switches from accidental activation, while slung or cased. Two things that kept this light from being the best option in the past. Problem solved!
    Light, Bright, Great beam, Ambi activation(same same both sides)
    Expensive(but most good stuff is)

    Does not fit Glock 30SF
    June 1, 2015
    Besides not fitting my Glock 30SF, it is a good quality light. The momentary on switch is pretty stiff. I'll end up putting it on either my shotgun or as a back up to my rifle light.
    Well made and bright.
    Doesn't fit the pistol I bought it for.

    Overall great light. A little loose on a 1911. Switch is tougher than most to switch on but momentary on works well

    awesome light for duty use
    October 5, 2014
    I use this light as my primary duty light with my glock 21 it fits great in my safariland holster and being surefire is always rugged durable and ready to use. I get great instant high lumen light at the press of the switch to quickly identify any threats and also induce temporary disorientation. perfect for low light no light building searches and excellent for any outside night activity. tactical runtime is low and I understand you can only do so much but would like to see a little more. also the rails that mate the light to the weapon are polymer which they have held up to daily abuse but would rather see aluminum instead, maybe the can sell a upgrade to switch them out? all in all fantastic from surefire you get what you pay for so price is right and I would always hands down recommend this light to others.
    ultra bight high lumen light great for identifying your threats and great spill for situational awareness
    low tactical run time, plastic rails

    This is a bright light without the bulk. Slightly longer than the x300 but definitely brighter. This isn't duty light mounted on the Glock 22.
    Bright, light weight, great price !

    Ask a Question
    By Bruce Anderson on April 10, 2013
    My duty weapon is a H&K USP40. Will this tactical light fit my weapon's rails or will I need an auxillary part?
    on April 10, 2013

    If your H&K USP has a picatinny or universal rail, this Surefire Weapon Light will fit. If it doesn't have picatinny or universal rails, you will need the Surefire MR09 mount which can be found here:

    By Sean on January 24, 2013
    Does this light fit the H&K UMP compact?
    on January 24, 2013

    If your UMP has standard picatinny rails, this Surefire Weapon Light will fit.

    Is it possible to upgrade my X-400 (170LUM Output) to the 500LUM output of the X-300?
    on March 13, 2013

    Surefire does not make a conversion head for the X400 to upgrade the lumen rating.

    By David Cavazos on April 13, 2013
    I am a LEO Can you recommend a holster from my Springfield XD 45/5" duty pistol that will accommodate the weapon and light? Thanks.
    on April 13, 2013

    We do not know of any holsters designed specifically to fit the X300 Ultra yet since the light is fairly new. However, we did find numerous forum posts stating the Safariland 6360 Holster designed for the standard X300 will fit the Ultra. We cannot guarantee the fit though since we have not tested it ourselves, but if you would like to see the holster you can view this link: We do not have the part number for a Springfield XD .45 in the option box yet but we can add it if you would like.

    By German Gonzalez on April 16, 2013
    Does this light feature a strobe function?
    on April 16, 2013

    The Surefire X300 Ultra does not have a strobe mode.

    By Brandon on December 24, 2012
    Will this light fit in the Safariland 6280 Holster made for the X300?
    on December 24, 2012

    Yes, it is the same size as the original X300.

    This Surefire X300-Ultra will not fit on the Walther P99QA's rails.
