Description
The SureFire X300 Ultra delivers a stunning 600-lumen beam focused by a precision TIR lens. Its specially selected high-performance LED is biased slightly towards the yellow-green part of the spectrum to which the human eye is most sensitive. This combination of extreme output and optimized off-white light color increases perceived light available for the user, creates a brighter surround beam for enhanced situational awareness, and increases the blinding effect on an opponent's dark-adapted vision. The X300 attaches to the Picatinny and Universal rails found on many handguns, and will fit many popular rail-less handguns by using SureFire' s MR adapter mounts. It features integral one-finger ambidextrous switching and can be equipped with SureFire' s optional DG handgun grip switch. Also attaches to the Picatinny rails on long guns, and can be activated via optional remote switches. IPX7 waterproof to 1 meter for 30 minutes

This is a very bright light that just feels and feels like solid quality. I have it mounted on a Glock 17 and it fits perfectly. Pros: Solid, quality construction Metal housing Lightweight Bright Easy to operate Easy to install/remove Balance It just feels like a solid light, and even looking at it in the package you could tell it would be a quality product. The aluminum body is strong and makes the whole unit lightweight. This light is very bright and is pretty easy to turn on with one finger. Momentary on is accomplished by pushing the switch forwards (towards the lens) and is easily accomplished with an outstretched finger without changing grip. Constant on requires spinning the switch clockwise OR counterclockwise. I was able to do this with the same single finger as momentary on. Using the lever lock, it's easy and quick to install and remove the light. Just pull down on the lever and slide it on/off. The other mounting method, the Rail-Lock, is also easy to install. The Rail-Lock is similar to the lever lock in that it locks into a rail slot but you need to use an allen wrench to tighten a sort of friction lock against the weapon. Both are very solid mounting options though. This light doesn't weigh much, 4 ounces according to SureFire, but it does help balance the weapon in hand. Cons: No light lockout Changing batteries requires removing the unit from the weapon No strobe Expensive There is no lockout on the light, so it is possible that the light could get turned on accidentally in a weapons case or bag. Changing the battery does require removal of the light from the weapon. On a pistol it would most likely be backed up to the trigger guard, and on a rifle the battery door opens towards the rail and thus cannot open far enough to remove the battery. If you install this light on a rail riser, you may be able to open the door without removing the unit. However, as I said above, it's very easy to install and remove the unit so this is not too much of a problem. This unit does not have strobe, it wasn't advertised to have it but some of the other light in this range to have that feature. It is an expensive light for just being a light. However, for the brightness and quality of the unit I would say it is justified. Recommendations: It's an excellent light. There are brighter ones, and cheaper ones. This is the first weapon light I have used, so I cannot compare to others. However, recognizing the quality in this unit I would definitely recommend this light to others looking for one.

Was worried that I would be buying a clone becausethe price was $100 less than everywhere else, but I got an authentic Surefire. It's bright, works and fits perfectly. Surefire sets the standard for quality and it lives up to the hype. I like the intuitive functioning of the switch press for momentary and up/down for constant, it's WAY better than Streamlight. You get what you pay for, love it so much I purchased a second one for my rifle.

I'm a 5 year police officer with the majority of my time spent on nights. I didn't make it a year before I decided I needed a weapon mounted light for my Glock 22. I looked at the Glock light, Streamlight TLR series, Surefire X200 and the Surefire X300 (which had just come out). I did a ton of research and settled on the X300 and had the light for almost 3 years. I got out of LE and sold most of my nice toys, including the X300. Fast forward two and a half years (May 2013) and technology has made leaps and bounds in LED flashlights. I'm starting over again working nights on patrol and needed a tach light for my Glock 17, so I ordered my Surefire X300 Ultra. This light is leaps and bounds better than it's predecessor. I personally don't think it's "too bright", although I've seen that written a few times. At night, it will light up a pitch black yard on a house perimeter check or the inside of a vacant building. It's solid and as close to bulletproof as any light is going to be. It's very, very lightweight....honestly, I can just barely tell the difference in weight when the light is on there vs when it's not. 500 lumens is truly retina burning. For those who work days, you need a light as well. It's nice to have a free hand to open doors on a house or building search and we all know it's dark in there as well, even when it's daylight outside. You don't have to be a cop. This light is perfect as a home defense pistol, resting insid a quick access safe or on a nightstand. The whole purpose of having a light attached to your pistol is to have both hands there to support your pistol grip. If the SHTF and you need to crank rounds off, you're going to want that extra control of your pistol to recover from recoil and put more accurate rounds on target. It has adjustable Allen screws, and comes with the wrech in the package, to adjust the tightness in which it attaches to your weapon. I loosened my considerably so that it's easier to get off when I want to carry my G17 as a CCW in an IWB holster. When it's back on duty or on the shelf, it slides right back on the pistol and you hear an audible "click" to let you know it's securely attached to the weapon. Even with the screws loosened, it has zero movement and its rock solid. Bottom line: if you want the best light out there, this is it. I use mine as a tool to bring me home safe every night, so I want the best. Surefire X300 Ultra is the best IMO.

Upgraded to this light from the regular X300. I also have an older M6 and a TLR1 by Streamlight. These Surefire lights are more than the Streamlights but I truly feel they are worth it. Im an LEO with over 10 years on. I have been a proactive officer the entire time and have really put these lights through it. The TLR was a fine light but striking a window of a fleeing veh I bent the bezel. It still worked(the light, window didn't break) but bent. I also had an issue with the switch sticking in cold weather. Its never a good feeling to pull your gun and find your light is dead because the switch was stuck on. The Surefires however have never given me one issue and other than some scratches it show no signs of wear. I have beat them up and they take it like a champ. I also added the XS CSAT to the end of my X300 and plan on adding it to the X300U as well. They make breaking a window a breeze and best of all to the public it is not noticeable like swinging a baton. It also leaves your gun in hand while establishing a line of communication both visibly and verbally to the dirtbag inside the veh who is refusing to comply. They also make them for the TLR if you go that route. I am the gear guy at work and whenever I am asked what pistol light an officer should get I answer Surefire without hesitation. You will not find a better duty light to trust your life with.

I was looking at different lights but when it comes to reliability, most people are still leaning towards Surefire and the price isn't really that much more. I got this X300 Ultra to mount on a Springfield XD(m) .45 3.8" barrel. Using the included (pre-mounted) rails, it was ready to go right away. I had to loosen the rails a bit to mount them then use the included allen wrench to tighten them. It was a tight fit to get the wrench in since some of the barrel was in the way, but it is held securely, that's for sure. There are other mounting plates included, but I didn't need them. Since the barrel is shorter in this case, the light does extend quite a bit past the barrel's end. I'm not using this for concealed carry (yet?) so it's not a big deal. The switch is easy to use for temporary or constant lighting and it is blinding, even in broad daylight. I'm sure in a dim/dark environment this would blind/disorient any intruder and the contrast from dark to light could temporarily impact me as well! Hopefully we'll never be in those situations, but it's nice to know that if you are, that you'll have a powerful weapon light. I can't comment on the battery life but so far (over a month with occasional testing), but it should have a decent shelf life according to other reviews. I also bought a pack of batteries as well.

The previous Surefire light (x300) was a very high-quality light, as you can see by the many high reviews. This one (Surefire x300 Ultra) is basically the same, but MUCH brighter. (besides the slight bevels on the end of the light, which look cool, but do nothing that I can tell). Pros: -incredibly sturdy feel -easy to mount -easy to install/replace batteries -comes with the 2 required batteries -SO bright (500 lumens vs the previous 170) -price - though $299 seems a pretty hefty price for a light, when you consider the previous version (170 lumens) is $275, I'd consider paying only an additional $24 dollars for 500 lumens to be a great deal. -ambidextrous (can use with right or left hand easily as it has a switch on both sides) -still fits in the same holster as the x300 Cons: -price - yes, I know I put this in the pros too, but - it is still $300 for a light. Do I regret paying it for such a sturdy, bright, great light? Absolutely not. Side note: I read some online questions similar to: "Is it so bright it blinds you when bouncing off a nearby wall?"...etc. This isn't a problem. While it IS incredibly bright, at no time did I feel its bounced light caused any issues.

As a disclaimer, I got my light via Amazon Warehouse, which sells items with damaged packaging or returned items at lower rates. I got mine for a total of $190 after tax and shipping. For THAT price, it just beats every other light in terms of reliability. In terms of features, it's somewhat lacking but that is indicative of a simper design. The more complicated a design, the more parts there are to fail. I also ordered it and received the A model with quick detach, though the A or B model was not listed on the page at the time I ordered it. Make sure to check with Amazon Warehouse if you particularly want one version or the other. I will say, I have an uncommon pistol, H&K P30L, and it took some adjustments to fit the light on. However after that, it secures very well and provides excellent illumination. Switches feel a bit short for me, but there are aftermarket options for extended switches and everyone has different hand sizes. Also using gloves helps a bit.

When first using this light around other tac lights, it is obvious that this is the pinnacle of what is currently available. The light itself is rugged and very well constructed. Mounting is easy, and depending on the weapon it is being mounted to, fit can be enhanced by installing either the universal bar or picatinny bar. With the picatinny bar installed the light locks up like a bank vault on my SP-01. The beam is very bright and defined. It has a large amount of peripheral 'splash' that allows the user to illuminate an entire room in one burst or allows the user to illuminate a target without the danger of muzzling whatever is down range. The hot spot of the beam is extremely intense and will not only give you a positive ID of your target but will undoubtedly blind them as well. This is far and away the most intense weapon light I have ever used even when compared to previous Surefire products I have owned [x400]. If you need a weapon light buy this and you will not be disappointed!!! Also, another promising weapon light with a reduced lumen output is the INFORCE APL.It has very similar characteristics to the X300 Ultra, but with extremely easy to use paddle switches and light distribution. It has nowhere near the 'horsepower' that the X300 Ultra has, but is a very capable weapon light.
