Released in October 2024, the Streamlight TLR-1 HP-X is a high-output, rail-mounted tactical weapon light designed for duty, home defense, and professional applications. Producing up to 1,500 lumens with a powerful, wide beam, it enhances target identification and situational awareness in low-light environments, while remaining compatible with most full-size handguns and long guns.

Compared to earlier TLR-1 models, the HP-X delivers significantly increased light output and introduces several key upgrades, including front-loading battery access and interchangeable rear paddle switches, available in both “High” and “Extended High” configurations to suit various grip styles and ergonomic preferences.

Measuring 3.45 inches in overall length, the TLR-1 HP-X is constructed from durable 6000-series machined aircraft-grade aluminum with a black anodized finish that resists corrosion, chemical exposure, and impact.

The paddle switches are molded from high-impact polymer and allow for ambidextrous activation of both momentary and constant-on modes. A programmable strobe function is also included, which can be enabled or disabled based on user preference.

A Borofloat high-temperature, impact-resistant glass lens protects the LED emitter and helps focus the beam out to 283 meters. The LED itself is rated for a 50,000-hour operational life, ensuring long-term performance without degradation.

Thanks to its dual-fuel capability, the TLR-1 HP-X can operate using either two Streamlight SL-B9 USB-C rechargeable lithium-ion batteries or two standard CR123A lithium batteries. With SL-B9s, the light delivers 1,500 lumens and runs for about 60 minutes, with a 2.5-hour charge time. With CR123As, output is reduced to 1,000 lumens, but runtime increases to approximately 90 minutes—providing flexibility depending on mission needs or battery availability.

The battery compartment is sealed with a rubber gasket, giving the TLR-1 HP-X an IPX7 waterproof rating (submersible to 1 meter for 30 minutes).

Included with the light are a variety of rail keys, enabling secure and proper fitment across a wide range of handgun makes and models, including Glock, Picatinny, S&W, Beretta, and others.

As of this review, the TLR-1 HP-X is available only in black.

Product Evaluation Scores:

• Cost – Excellent (5/5): The TLR-1 HP-X was priced competitively at around $180 – $210 (depending on the retailer source), and offered an exceptional balance of features, durability, and performance that justified its cost. While the Surefire X300 Ultra retailed higher—typically between $270 and $320—primarily due to its established brand reputation and rugged reliability, the HP-X delivered comparable, if not superior, output and versatility at a noticeably lower price point. The Surefire Turbo, a mid-range option costing $180 to $210, lacked some of the HP-X’s advanced features such as higher lumen output and improved battery flexibility. On the more affordable end, the Nightstick TWM-30, priced around $100 to $130, compromised on brightness and housing materials to hit its lower price. The HP-X’s value lies in its combination of a high-intensity LED capable of 1,000 lumens, durable machined aluminum construction, and versatile battery compatibility—all packed into a well-balanced, lightweight design. This made the HP-X an excellent choice for users seeking top-tier performance and ruggedness without paying the premium price of some competitors, effectively bridging the gap between affordability and professional-grade quality.
• Comfort – Good (4/5): From a comfort perspective, the TLR-1 HP-X featured an ambidextrous momentary/constant-on switch that was easy for the end-user to access and operate with either hand, allowing quick activation without significantly altering their grip. Its balanced weight distribution and relative compact size helped maintain a natural grip and overall firearm maneuverability, minimizing any impact on individual aim or handling during rapid shooting. The light’s profile in-line with the trigger guard reduced the risk of snagging during holstering and drawing, which made weapon transitions smoother. Constructed with a durable aluminum body, the HP-X managed heat effectively, keeping it comfortable to use over without excessive heat radiance. However if left on continually, the heat from the light emitter would become notable after several minutes (though still not scalding). The latter was within normal expectations of weapon lights of this type and lumen output. Additionally, the option to select between momentary and constant-on modes gave the end-user the functional flexibility to suit different preferences and tactical scenarios. Overall, the design supported secure handling and reliable operation in a variety of conditions.
• Durability – Excellent (5/5): The durability of the Streamlight TLR-1 HP-X was attributed to its rugged construction, utilizing 6000-series machined aircraft-grade aluminum anodized to MIL-A-8625 Type III standards, and provided resistance to impact, abrasion, and corrosion. The Borofloat® glass lens, known for its high thermal and mechanical shock resistance, endured recoil forces and five drops from approximately six feet onto finished concrete without fracturing (although some surface marring was noted). Internet research has shown that some users have experienced failues with the hinge fracturing, though that was not experienced here. Despite some superficial surface scuffs, the light’s overall structural integrity remained intact with no deformation or compromise. The light was rated to IPX7 waterproof standards, meaning it can withstand immersion in up to one meter of water for 30 minutes; in practical testing, it reliably operated after heavy rain exposure during range use, though it was not fully submerged during evaluations. The tool-free quick-release mounting system securely locked the light to the firearm, maintaining zero shift under recoil and repeated attachment cycles without any cracking or mechanical failure. Several additional rail-keys were included to adapt the light’s mounting system to the most common types of pistol mounting rails. Additionally, the 6000-series aluminum body facilitated efficient thermal dissipation, preventing excessive heat buildup during prolonged high-lumen output, and the light did not experience any thermal shutdowns or electronic malfunctions throughout testing.
• Functionality – Good (4/5): Functionally, from directly out of the box the TLR-1 HP-X offered a straightforward ON/OFF and momentary activation use, delivering a consistent 1,000-lumen output with CR123 batteries that could be applicable for a variety of tactical and defensive situations. However, the HP-X did not come with the SL-B9s necessary to step the output up to 1,500-lumens and these are something that the end-user would need to purchase separately if they wish to extend the light to its fullest capability. Alternatively, consumers could opt to get the TLR-1HP-X USB which then comes with the SL-B9s. While both lights can utilize either power supply, the difference between the regular HP-X and the HP-X USB is what batteries come included with it. Otherwise, the ambidextrous switch design allowed activation from either strong-side or support-side of the light, giving flexibility for end-users with different hand sizes and shooting styles. The compact and robust aluminum housing contributed to a balanced feel even on compact-size handguns, minimizing any noticeable impact on handling or recoil management. The light featured a secure, tool-free mounting system compatible with Picatinny and Glock-style rails, ensuring reliable attachment even under repeated recoil. Heat management of the light during continual use was effective, allowing for extended use without flickering, overheating, or unintended shutdowns. Overall, the TLR-1 HP-X functioned as a dependable weapon light, offering a balance of brightness, durability, and ergonomic design that supported practical use in law enforcement, tactical, and civilian contexts.
• Weight – Average (3/5): The TLR-1 HP-X weighed in between 5.19 ounces with SL-B9 rechargeable batteries, and 4.94 ounces with CR123A lithium cells, a weight largely driven by its high-capacity power source. The remainder of the weight stemmed from the light’s precisely machined aluminum housing, which was engineered for maximum durability and impact resistance. This robust construction ensured reliability in demanding conditions without compromising handling. Compared to similar weapon lights like the Surefire X300 Ultra (4.0 ounces with batteries), Surefire Turbo (4.4 ounces with batteries), and Nightstick TWM-30 (5.4 ounces with batteries), the HP-X’s weight fell well within the expected range for lights of its performance and build quality. Importantly, despite its solid construction, the HP-X maintained excellent balance on a full-size handgun, neither pulling the muzzle downward nor impairing rapid target acquisition during firing.

Overall Rating – Good (21/25)
