SureFire P2X Fury® with IntelliBeam™

For your consideration is the SureFire P2X Fury® with IntelliBeam™ Technology – with Auto-adjusting variable-output LED. While this is not the first example of a flashlight (or headlamp) that utilizes such technology, it is the first from SureFire, and in my humble opinion, the most effective execution.

(Some text taken from SureFire web site)

This innovative, automatically adjusting version of the original P2X Fury takes full advantage of the variable-output capability of one of SureFire’s brightest and most popular LED flashlights. Our proprietary IntelliBeam™ Technology—an intelligent sensor and microprocessor-based system—continuously evaluates your environment and seamlessly adjusts light output, from 15 up to 600 lumens, based on the scope of your surroundings. Just press or click its tailcap switch to access this auto-adjusting mode, which delivers just the right amount of light output. Return to off and press or click again within one second to activate max-output/tactical mode, which locks in all 600 lumens—ideal when maximum output is what you need.

The P2X Fury with IntelliBeam Technology—like all other Fury models—uses a high-performance LED to deliver its perfect light that’s focused by a parabolic reflector into a smooth, comparatively wide beam with a bright central area and generous peripheral light.

You can just barely observe a minor artifact in the beam (around 9 o’clock position) – caused by the aforementioned sensor

This special P2X Fury model was also engineered to preserve dark-adapted vision by actually evaluating the environment instantaneously before turning on; it will never activate in high-output in close quarters while in IntelliBeam mode. This automation is all about allowing users to focus on the job at hand and not spending time manipulating their illumination tool to get the perfect output level.

I spent a couple of weeks using the light for my early morning dog walks. The variable beam works quickly – turn the light on with it shining towards a near object and the level stays low – swing up to a distant target and it quickly ramps up to full brightness.


Full brightness at any distance is quickly activated by ‘double clicking’ the solid, tactile feeling clicky tail switch.

I measured the output of the light in my integrating sphere – in the sphere the light stepped down to around 30 lumen and around 610 lumen at full output. SureFire has always been conservative with their lumen ratings, and this light is an example of that tendency. No way of really measuring the various output levels in real use – but when shining at my watch face within a few inches the light stepped down to a level low enough to illuminate the watch face without being so bright as to create too much glare to be able to read the face.

The light is built like a tank and has the excellent SureFire lifetime warranty

Criticisms? I have a few. A user is dependent on SureFire’s programming to set the levels – it would be nice to have an additional ‘mode’ that allows for manually setting a low and medium ‘locked’ level.

I am a tint snob, and the tint of this light has a sickly greenish hue when using indoors. You don’t really notice it outdoors. Still, most light manufacturers – especially quality manufacturers like SureFire – have begun sourcing better bin LEDs that have a nicer, more neutral tint.   Some people may not care about the tint, but many do.

SureFire has always commanded a price premium and this light is no exception. List price is $229 and is readily available for around $170.

Love firearms and flashlights – and they go well together. I’ve been admiring and writing about quality flashlights for about 9 years…built my own integrating sphere….done a few mods. Proof positive that a 59 year old can still love toys!

    Um… How about comment on what I thought would be the most obvious flaw in a tac light!?

    If I’m shining my light at someone intentionally to keep them blinded, if they shine a light at me, it cuts my light down to practically off? – seems like a failure for being a real tac light.

    Can you test Dan?

    • Barry

      Double click the button and it’s automatically on high output, right?

      • Bill

        That’s sort of backwards – from a user’s perspective, as a fighting light I’d want full power with no dithering around. What happens if I click it 3 times? 4 times? 5 times?

        Lights that use the main switch for adjusting modes are a lot like submachine guns – it takes a lot of practice to fire a predetermined number of rounds, like 2, 3, or 5, or 7, on demand.

        • Cymond

          Agreed. A tactical flashlight should never use the power switch to adjust the modes (although that’s just fine for mundane, utilitarian flashlights).

    • Dan M

      Yes, I did test that – please forgive the omission in the write up. It does step down when you shine another light directly into the lens from around 2 feet or less, but it’s a diminishing problem and increasing distance. It should still be considered a concern, though, and has been discussed in detail in a major flashlight forum. Agreed that the double click eliminates the issue, but also agreed that in a tense, tactical situation you might not think to double click. Some manufacturers (Streamlight, for example -and of course many others) give you programming options. Surefire might want to consider such a thing for this light. And I for one would like to be able to default to a “low then high” or “high then low” setting, bypassing the Intellibeam. Of course, you can just buy the P2X Fury dual setting and have a 15 / 600 lumen switch, but then you won’t have the Intellibeam option.

    Not to bash Surefire because their products are quality but if you told a random person that you bought 3 flashlights for $500-600, they would think you are crazy.

    With the price of led’s constantly going down, I don’t see how a company can command such a price premium when you can get over 10 energizer brand led flashlights at Walmart for the same price.

    • 1. Made in America (except for the actual LED which is a foreign purchase)
      2. Excellent Customer Support
      3. Bullet Proof Lights
      4. Lifetime warranty

      5. Well thought out designs for their particular use

      I’ve purchased cheap Chinese lights, even some of the “high end” Chinese lights. They almost always break. And if they have a lifetime warranty it is through China, or they ask your retailer to handle things. Which results in hit or miss (mostly miss) support after the sale. And then they all kinds of modes which require you to tap dance the cap to get what you want.

      I compare that with Surefire where I am supporting American jobs. When something breaks Surefire customer support is a phone call away. And they handle everything.

        Can I use a 17670 Li Ion primary instead of two CR123 without a drop in output?

    • Sianmink

      Those aren’t near the quality of even the Olight and Fenix lights out there, and none of them will stand up to the abuse that a Surefire can absorb trivially.
      Will the cheapo light work just fine for you? Probably. Provided you don’t fall into too much water or drop it from more than shoulder height or let it get too hot.
      The only thing that will generally go wrong with a Surefire is you could farg up the switch if you’re particularly abusive, and they’ll replace it for you NQA in under a week. And that’s why they cost so much.

    • Cymond

      Heck, even Elzetta is cheaper than this. If the Elzetta marketing is true, then they’re truly amazing flashlights. Their videos show them hammering nails and disassembling underwater.

    For that price, I can get two Four Seven Maelstroms.
