If you’re a shooter, you already know how crucial it is to have a reliable and powerful light mounted on your firearm. The Streamlight ProTac Rail Mount HP-X Pro packs a serious punch in terms of brightness, durability, and versatility—making it one of the most exciting new weapon lights we spotted at NSSF SHOT Show 2025. I’ll walk you through everything I’ve learned about this impressive piece of gear, so you can see why it’s a top contender for your next rifle or carbine upgrade.
Below, I’ll also include some insights we gained from talking to Streamlight representatives at SHOT Show 2025. Whether you’re interested in the ProTac Rail Mount HP-X Pro itself, or you want to hear about Streamlight’s other new products like the TLR series or the MegaStream handheld, keep reading. This review is packed with detailed information, firsthand impressions, and a comprehensive breakdown of features that any firearm enthusiast will appreciate.
Why the Streamlight ProTac Rail Mount HP-X Pro Stole the Show
1. Impressive Candela and Lumens
Let’s start with the statistics that really make the Streamlight ProTac Rail Mount HP-X Pro stand out:
|
|
- 105,000 Candela
- 800 Lumens
- Two-hour runtime when powered by their SL-B26® rechargeable battery
- 1.5-hour runtime using CR123A batteries
While 800 lumens might not sound astronomical in a world where some lights boast 1,500 or even 2,000 lumens, the 105,000 candela rating is what truly sets this model apart. Candela reflects the intensity of the beam at its brightest point and translates into how well the light can reach downrange. With 105,000 candela, you’re getting a concentrated hotspot that excels at target identification, whether you’re scanning a dense forest on a hunt or clearing a dark hallway in a home-defense scenario.
2. Multi-Fuel Battery Flexibility
One of the unique perks of the Streamlight ProTac Rail Mount HP-X Pro is the multi-fuel setup. You can power this light with a rechargeable SL-B26® battery or use CR123A batteries if you prefer the convenience and widespread availability of disposables. That flexibility is especially handy if you’re in a pinch and can’t recharge, but you have a stash of CR123As on hand.
3. Jack-Cap Tail Switch and Remote Pressure Switch
Streamlight has thought carefully about the user interface. This weapon light includes both a push-button tail switch and a port for a remote pressure switch. The tail switch offers a traditional handheld activation when needed, but you can also plug in the pressure pad for dedicated rifles or carbines. As Brett from Streamlight said at the show, this redundancy ensures that if your pressure switch goes down for any reason, you still have a reliable backup built right into the tail cap.
4. Durable Design and Easy Mounting
Built from rugged materials and designed specifically to handle recoil, the Streamlight ProTac Rail Mount HP-X Pro is prepared for hard use. You can mount it using the included Picatinny rail grabber, or take advantage of the M-LOK® mount that comes in the box. The light is also rated for impact resistance and waterproofing, so you don’t have to baby it in adverse conditions.
Insights from SHOT Show 2025
At NSSF SHOT Show 2025, we were thrilled to see Streamlight’s impressive booth, packed with new and updated products. I spent a good amount of time talking to two Streamlight representatives, Brett and Brian Osborne, who were more than happy to share the inside scoop on their latest innovations.
Brett’s Take on the ProTac Rail Mount HP-X Pro
Brett highlighted how meticulously Streamlight approaches the design process. From the very beginning, they consider the application of each light: whether it’s destined for law enforcement, military, hunting, or civilian home defense. The Streamlight ProTac Rail Mount HP-X Pro benefits from this thoughtful planning, featuring:
- High-output LED that focuses into a tight, high-candela beam
- Ten-Tap® programming which allows you to customize the light modes (High/Strobe, High Only, Low/High, etc.)
- Robust aluminum construction for durability in the field
As Brett mentioned, the design process doesn’t stop at raw performance. Streamlight also tests for recoil, waterproofness, and user-friendliness. In his words, “It’s about balancing lumens, candela, runtime, and reliability to create the best possible tool for the user.”
Brian Osborne on the TLR Series and More
While I had Brian Osborne’s attention, I also picked his brain about Streamlight’s pistol lights and other rifle lights on display:
- TLR-1 HLX – A 1,500-lumen pistol light that remains one of Streamlight’s biggest success stories.
- TLR-7 HLX – Now upgraded to 1,000 lumens, with 22,000 candela, and an option for a rechargeable battery.
- TLR Sub Series – Compact lights designed for the popular subcompact pistols on the market today, available with or without lasers.
- ProTac Rail Mount 2.0 HP – Another rifle-oriented light boasting 85,000 candela at an extremely bright output, a strong contender for those wanting a slightly different beam profile than the HP-X Pro.
- MegaStream Handheld – A handheld flashlight featuring a USB-C charging port, capable of high performance in a more traditional form factor.
- Wedge Line – Updated with new color options, making it easier than ever to coordinate or personalize your EDC setup.
Real-World Applications for the Streamlight ProTac Rail Mount HP-X Pro
Home Defense
A weapon-mounted light is indispensable for positive target identification in low-light or dark conditions around the house. The Streamlight ProTac Rail Mount HP-X Pro offers both a powerful hotspot and enough spill to navigate tight corners. The high candela ensures you can illuminate threats or suspicious areas far across your property, and the robust construction means it won’t fail when you need it most.
Hunting and Outdoors
If you’ve spent any time in bear country or you often camp in areas with nocturnal predators, having a bright, rugged weapon light can be a lifesaver. A quick step outside your tent into the pitch-black woods is less nerve-wracking when you have the means to spot threats before they get too close. The ProTac Rail Mount HP-X Pro excels here thanks to its high candela beam, which helps pick out details in the distance more effectively than lights with higher lumens but lower candela.
Tactical and Law Enforcement
For those in tactical or law enforcement roles, reliability is non-negotiable. Streamlight weapon lights have earned a reputation for surviving the rigors of patrol work, training scenarios, and even military deployments. With the ProTac Rail Mount HP-X Pro, you get:
- Remote pressure switch for quick activation while maintaining proper grip
- Extra-durable body that can withstand the pounding of repeated rifle recoil
- Simple battery changes that don’t require you to remove the light from the firearm
Comparing Lumens vs. Candela
There’s often confusion about the difference between lumens and candela, so let’s break it down:
- Lumens measure the total amount of visible light emitted by a source. In other words, it’s a measure of how bright the light appears overall.
- Candela measures the intensity of the light in a particular direction. A light with a high candela rating has a more focused beam, which translates to better “throw,” or how far the light can effectively reach.
Some shooters might see “only” 800 lumens on the Streamlight ProTac Rail Mount HP-X Pro and wonder if that’s enough. Here’s the key: 105,000 candela is extremely high, meaning the beam is tightly focused. You get the advantage of both a bright center hotspot for long-distance identification and enough peripheral spill for situational awareness.

Setting Up and Installing the Streamlight ProTac Rail Mount HP-X Pro
Step 1: Choose Your Battery Option
Decide whether you want to run the SL-B26® rechargeable battery or CR123A disposables. Both are included, so you can experiment with each power source and see which suits your needs best.
Step 2: Mounting
Use the included Picatinny rail grabber or the M-LOK® adapter if your setup favors that system. Follow the simple instructions provided by Streamlight, and make sure everything is torqued to the appropriate spec so your light stays secure even under heavy recoil.
Step 3: Install the Pressure Switch
If you decide to go the pressure switch route, simply plug it into the jack-cap tail switch. You can route the cable along your rail using the supplied zip ties or optional tape. If you prefer the classic tail cap switch, leave the remote pressure switch off and you’re all set.
Step 4: Ten-Tap® Programming
Streamlight’s Ten-Tap feature allows you to customize the lighting modes. The default is typically High/Strobe, but if you want just High or a High/Low combo, you can easily switch modes by following Streamlight’s quick instructions. This is especially handy if you have a specific preference for how the light operates in high-stress situations.
The Bigger Streamlight Lineup at SHOT Show 2025
Although this blog focuses on the Streamlight ProTac Rail Mount HP-X Pro, it’s worth mentioning how it fits into Streamlight’s broader lineup. For pistols, the newly updated TLR lights—like the TLR-7 HLX—offer impressive outputs (up to 1,000 lumens) in smaller packages. For subcompact pistols, the TLR Sub line offers flexible laser/no-laser variants. And if you’re looking for a high-candela rifle light with different beam characteristics, the ProTac Rail Mount 2.0 HP might be up your alley.
Streamlight also introduced some interesting handheld options like the MegaStream, a USBC rechargeable flashlight that aims to marry convenience with performance. And for everyday carry fans, the Wedge lineup now comes in multiple colorways, letting you customize your carry flashlight style.

Personal Impressions from the Show Floor
As someone who has tried a variety of weapon lights over the years, I’m particularly impressed with how Streamlight balances performance and price. They’ve always been known for offering a more budget-friendly option compared to some high-end boutique competitors, without sacrificing reliability. During our conversation at SHOT Show 2025, it was clear how passionate the Streamlight team is about ensuring their products hold up under real-world conditions—whether that’s a law enforcement officer’s patrol rifle or a hunter’s personal AR-15.
Having the chance to physically handle the Streamlight ProTac Rail Mount HP-X Pro also gave me a sense of its build quality. The aluminum body feels substantial without being overly heavy, and the control surfaces are well-thought-out. The inclusion of the Ten-Tap® programming, remote pressure switch, tail cap, and multiple mounting options all indicate that Streamlight truly listens to user feedback.
Maintaining and Troubleshooting the Streamlight ProTac Rail Mount HP-X Pro
To keep your light in top shape:
- Check the O-Rings – Ensure the O-rings are in good condition to maintain waterproof integrity.
- Clean the Lens – A simple wipe-down with a microfiber cloth keeps your tempered glass lens clear.
- Secure Your Pressure Switch – If you use the remote switch, confirm that all cable routing is tight and isn’t snagging on other gear.
- Charge or Swap Batteries – If you’re using the SL-B26®, follow the recommended charging guidelines. If you prefer CR123As, carry an extra set.
If you ever run into issues, Streamlight has a solid reputation for customer service. Their warranty support is often praised in online firearm and gear forums. For additional details, check out the official Streamlight Warranty Page.
