The TLR-1 HL-X and TLR-1 HP-X represent the current generation of Streamlight’s full-size pistol weapon light, splitting the lineup into two distinct roles: the HL-X for broad flood illumination, and the HP-X for focused, long-range candela. Both share a common body architecture, ambidextrous switching, and the front-loading battery compartment that defined this product refresh, but they solve different problems for the armed citizen.
TLR-1 HL-X: The All-Around Defensive Light
The HL-X outputs 1,500 lumens and 20,000 candela on the included Streamlight SL-B9 rechargeable batteries. Running standard CR123A cells drops output to roughly 1,000 lumens — matching the older TLR-1 HL it replaces. At 25 meters, target identification is clear and unambiguous. Effective engagement capability extends to 50–75 meters and beyond, which covers the vast majority of realistic defensive scenarios a civilian or law enforcement officer will face.
The HL-X has established itself as one of the most popular pistol lights in both the civilian and law enforcement markets, competing directly with the SureFire X300U at a lower price point. The performance-to-cost ratio is the defining advantage. Shooters who need a proven, durable weapon light on a fighting handgun without paying top-tier SureFire pricing will find the HL-X covers the requirement decisively.
TLR-1 HP-X: High-Candela for Distance
The HP-X trades raw lumens for focused throw. On rechargeable batteries it produces 1,300 lumens but 77,000 candela — nearly four times the candela of the HL-X. On CR123A cells, output is 1,000 lumens and 53,000 candela. That translates to a beam distance of 555 meters with rechargeable batteries. The HP-X bezel is noticeably longer than standard TLR-1 models to accommodate the reflector geometry required for this kind of throw.
The HP-X’s candela-heavy profile parallels what the SureFire Scout PRO Turbo does for rifles — pushing positive target identification to ranges where a wider flood pattern would wash out. For pistol use, this is a niche tool. Most indoor and close-range defensive encounters are better served by the HL-X’s broader beam. The HP-X makes more sense on a duty-size pistol used in rural or open environments where threat identification at distance matters, or on a full-size handgun staged alongside a home defense loadout where illumination at distance through hallways and open areas is prioritized.
Front-Loading Battery Compartment
Both models use a front-loading battery compartment that allows battery changes while the light remains mounted on the pistol rail. This is an ergonomic change from the older TLR-1 HL, which required removing the light from the gun to access the battery. For users who stage a weapon light on a nightstand pistol or in a vehicle staging setup, the ability to swap batteries without disturbing the holster fit or re-zeroing the light to the frame is relevant. The SL-B9 rechargeable batteries are the preferred power source — they deliver peak output and are economical over time. Dropping to CR123A cells still yields solid performance equivalent to the previous-generation HL.
Switch Design and Ergonomics
The switch system on the HL-X and HP-X is one of the strongest arguments for these lights over competing options. Both feature ambidextrous paddle switches with two activation methods: push down for momentary activation, push inward for constant-on. Each light ships with both a standard rear paddle switch and an extended high rear paddle switch, allowing the shooter to choose the profile that best suits their grip.
A key practical consideration for defensive carry: the low-profile switch option can be positioned on the trigger-finger side of the light, reducing the risk of accidental activation when the trigger finger enters the guard. The standard (taller) switch stays on the support-hand side for primary activation. This asymmetric switch setup is a deliberate ergonomic choice that takes very little training to internalize. Compared to the SureFire X300’s rocker switch, the TLR-1 HL-X switches require less deliberate practice to activate consistently, which is a meaningful advantage for shooters with small to medium hands or for those still developing their drawstroke under stress.
Both lights also include Ten-Tap programming: pressing the momentary switch ten times and holding on the tenth press toggles between standard and strobe modes. Strobe is a secondary feature — for defensive use, constant illumination for positive target identification should be the default.
Mounting
Both lights attach via a universal rail clamp with a thumb screw, and ship with multiple mounting keys to fit Picatinny and proprietary rail systems across common defensive pistol platforms. The thumb screw should be tightened finger-tight plus approximately one-eighth turn — no more. Over-tightening risks cracking or deforming polymer pistol frames. This is a common mistake on Glock and similar polymer-frame pistols.
Holster compatibility is excellent for the HL-X due to its market dominance — both the T.REX Sidecar and Ragnarok support TLR-1-pattern lights. The HP-X’s extended bezel may require verification of specific holster compatibility due to its longer overall length of 3.7 inches.
Construction
Both lights are machined from 6000 Series aluminum with an anodized finish and feature unbreakable polycarbonate lenses. They are rated IPX7 waterproof. Weight is approximately 5.4 ounces for the HP-X; the HL-X is comparable. These are not fragile range toys — they are built to the same standard expected of a light that rides on a reliable defensive handgun.
Choosing Between Them
For the majority of prepared citizens — those carrying concealed, staging a home defense pistol, or building a coherent loadout from EDC to full kit — the HL-X is the correct choice. Its 1,500 lumens and 20,000 candela provide a broad, bright flood pattern that enables positive target identification at realistic defensive distances. It has universal holster support, widespread adoption, and a well-understood track record.
The HP-X is a specialized tool for situations demanding maximum throw. Shooters who regularly operate in open terrain or need to push identification range well past typical pistol engagement distances will find that the HP-X fills that gap. For most users, it is an interesting option rather than a first purchase.
Both models make a strong case relative to the SureFire X300U on value alone, and the switch ergonomics may actually be superior for many hand sizes.
