The Modlite PLHv2 is the general-purpose rifle weapon light head for shooters who need a broad, powerful beam at the distances where most defensive engagements actually happen — room-distance out to roughly 100 meters. Where the OKW head sacrifices peripheral illumination for a tight, long-reaching hotspot, the PLHv2 reverses that trade-off: it pushes a wider flood pattern that lights up hallways, yards, tree lines, and vehicle surrounds without the tunnel-vision effect of a pure throw head. For a prepared citizen whose rifle may serve home defense, vehicle staging, or neighborhood patrol, the PLHv2 is the more versatile default choice.
Performance Specifications
The PLHv2 produces 1,350 lumens and 54,000 candela. The lumen count describes total light output — how much area the beam fills — while candela measures peak intensity at the center of the hotspot. By comparison, the OKW head delivers significantly higher candela (roughly 69,000) but fewer usable lumens spread across the beam. The PLHv2’s balance yields a bright center with enough spill to identify threats, obstacles, and friendlies at the periphery of the beam — critical in any scenario where the shooter cannot afford to scan one narrow cone at a time.
The emitter is a 5700K cool white LED. Cool white provides high contrast against most surfaces and renders colors more naturally than warm or neutral tints, aiding target identification. The head uses an ultra-clear BOROFLOAT glass lens rated at 98–99% light transmittance, meaning virtually no output is lost to the lens itself. Cheaper lights with coated or polycarbonate lenses can eat 10–15% of output before light ever leaves the bezel.
The driver electronics inside the PLHv2 head are fully potted — encapsulated in a rigid compound that prevents solder joints and components from cracking under recoil. This matters because weapon lights fail at the electronics level far more often than at the emitter or body level; potted drivers are the primary reliability differentiator separating serious lights from consumer-grade products.
Body Options: 18350 vs 18650
The PLHv2 head threads onto both Modlite body sizes, and the choice between them is a runtime-versus-footprint decision that should be driven by the rifle’s role in a coherent loadout.
18650 body: The full-size option. It accepts either the proprietary 3500mAh 18650 rechargeable cell or two CR123A primary batteries, providing approximately 75 minutes of continuous runtime. For a patrol rifle, a home-defense gun staged in a quick-access safe, or any rifle that may need to run for extended periods without a battery swap, the 18650 is the default recommendation. The extra length is marginal on a 14.5” or longer barrel and adds negligible weight relative to the runtime gain.
18350 body: The compact option. It shortens the overall light package considerably, which matters on short-barreled rifles and builds where rail real estate is limited. Runtime drops proportionally — roughly half the 18650’s endurance. The 18350 body earns its place on suppressed SBRs, PDWs, and tight-rail setups where every fraction of an inch counts. For more detail on body selection, see Modlite 18350 and 18650 Battery Bodies.
Mounting and Integration
The PLHv2 uses the Scout mounting footprint, the de facto standard shared by SureFire, Modlite, and Cloud Defensive. This means the head-and-body assembly drops directly into any Scout-compatible mount — including the T.Rex Lightbar, Arisaka Inline and Offset mounts, and SureFire Scout ring mounts. Mount choice determines how far the light sits from the bore axis and how close to the muzzle it reaches, both of which affect suppressor shadow and handguard clearance.
On suppressed builds, the PLHv2 benefits from being pushed as far forward on the rail as possible — or extended beyond the rail entirely using a LightWing-style adapter — to minimize the shadow a suppressor casts across the beam.

PLHv2 vs OKW: Choosing the Right Head
The decision between PLHv2 and OKW is not about quality — both use the same body, driver potting, and lens standard. It is about engagement distance and use case.
| PLHv2 | OKW | |
|---|---|---|
| Lumens | 1,350 | ~680 |
| Candela | 54,000 | ~69,000 |
| Beam profile | Wide flood with usable hotspot | Tight throw with narrow spill |
| Best range | 0–100 m | 50–300 m |
| Primary use | Home defense, CQB, general patrol | Perimeter security, rural patrol, PID at distance |
Most civilian defensive scenarios fall within the PLHv2’s optimal range. If your rifle lives in a home-defense role, rides in a vehicle, or serves as your primary carbine for training and preparedness, the PLHv2 is the more universally useful head. The OKW earns its place on designated marksman or rural-security rifles where positive identification at 200+ meters is the primary mission.
Why the PLHv2 Matters
A rifle without a white light is an incomplete weapon system. The ability to positively identify a target before engaging is not optional — it is a legal and moral prerequisite in every defensive scenario a civilian will face. As covered in The Importance of a Rifle Light, the light is as essential as the optic and the sling. The PLHv2 delivers the output, beam profile, and durability to serve that role reliably.
For pistol-mounted lights filling the same identification role on a handgun, see The Case for a Weapon Light on a Carry Pistol. When operating under night vision, the PLHv2’s visible output complements but does not replace dedicated IR illuminators for passive operations.
