Modlite OKW v2: 95,000 Candela Weapon Light Specs, Beam Profile, and REIN 3.0 Comparison

The Modlite OKW v2 produces 95,000 candela and 1,300 lumens, a substantial jump from the original OKW's 69,000 cd / 680 lm. The new emitter and optic deliver nearly double the raw light output while increasing throw by 38%, all within the same head form factor.

The multi-mode configuration includes an admin mode at 15% of high output, providing extended runtime for low-light navigation and administrative tasks. This two-mode setup eliminates the strobe and medium modes that clutter many competitors, giving you direct access to high or admin without cycling.

The OKW v2 maintains the tightest hotspot in the weapon light market. Where balanced lights like the PLHv2 spread energy across a wide beam for peripheral awareness, the OKW v2 concentrates virtually all output into a focused center spot. The result: a calculated beam distance of approximately 616 meters, making positive identification possible at ranges where most weapon lights produce nothing useful.

This beam characteristic makes the OKW v2 the natural pairing for rifles running magnified optics. When you are using an LPVO at 4-6x on a 14.5-inch or 16-inch barrel, the OKW v2's hotspot illuminates exactly what your reticle is pointed at without flooding the surrounding area with light. This also minimizes backscatter through the optic in dusty or foggy conditions.

The OKW v2's candela-per-lumen efficiency (approximately 73 cd/lm) indicates highly optimized optic design. For context, the SureFire M640DFT Turbo achieves approximately 143 cd/lm (100,000 cd / 700 lm), while the REIN 3.0 reaches 80 cd/lm (100,000 cd / 1,250 lm). The OKW v2 sits between these competitors in efficiency while delivering substantially more total light output than the SureFire.

The OKW v2 is a new emitter and optic in the same form factor. Every body, tailcap, switch, and mount that worked with the v1 works with the v2. Modlite's tagline for the launch was "More Performance, Same DNA," and the numbers confirm it.

The most significant change beyond raw output is the addition of admin mode. The v1 was single-mode only: full blast or off. The v2's admin mode runs at 15% of high output, providing usable low light for navigation, equipment checks, and map reading without burning through a full-power cell. On the 18650 body, that translates to approximately 10.6 hours of admin-level illumination.

For existing Modlite owners, the upgrade path is straightforward: buy the OKW v2 head (approximately $189), unscrew the v1 head, and thread on the v2. Total time: 10 seconds.

The OKW v2 uses the same construction methods that made Modlite the benchmark for weapon light durability. The head is machined from 6061-T6 aluminum with Mil-Spec Type III hard anodizing. The driver is fully potted, meaning the electronics are encased in a solid compound that absorbs recoil forces rather than transmitting them to solder joints and connections.

Modlite rates the potted driver for select-fire SCAR 17 recoil, which produces significantly more impulse than any semi-auto AR-15. The BOROFLOAT lens transmits 98-99% of light output and resists impact better than standard glass. These are the same materials and construction methods used across the Modlite lineup, and they have accumulated years of field validation in military and law enforcement use.

One area where Modlite trails the Cloud Defensive REIN 3.0 is waterproofing. The REIN 3.0 carries an IPX-8 rating (100 feet for 24 hours). Modlite does not publish an official IP rating for the OKW v2, though the sealed construction handles rain and submersion in practice. If your use case involves extended water exposure or true submersion, the REIN 3.0 has the documented edge.

The OKW v2 head threads onto any Modlite 18650 or 18350 body. It is also compatible with the new FUEL body, the PDW350 and PDW650 compact bodies, and any SureFire Scout-compatible body from third-party manufacturers. This modularity is the core advantage of Modlite's ecosystem: one mount, one body, multiple heads for different applications.

A practical configuration for shooters who operate in varied environments: keep an OKW v2 head for outdoor use and a PLHv2 head for indoor/general-purpose work. Swapping takes seconds and costs nothing beyond the head itself. Compare this to the Cloud Defensive REIN 3.0, which is a single integrated unit with no head swapping. If you want different beam profiles from Cloud Defensive, you buy two complete lights.

Mount compatibility spans the entire SureFire Scout ecosystem: Arisaka offset mounts, Unity Tactical FAST, Haley Strategic Thorntail, and all SureFire OEM mounts. Tailcap options include Modlite's own clickie and momentary tailcaps, the new FUZE integrated switch (announced at SHOT Show 2026), and all SureFire-compatible remote switches including the SureFire SR07 and Unity TAPS.

The new FUEL body option ($350 for complete package with OKW v2 head) adds integrated features to the standard 18650 body form factor. This positions the FUEL as a premium alternative for shooters who want a more refined package without sacrificing modularity.

The premium throw-focused weapon light segment comes down to three contenders. Each takes a different approach to maximizing candela, and the right choice depends on what you prioritize beyond raw output numbers.

OKW v2 vs Cloud Defensive REIN 3.0

The REIN 3.0 wins on raw candela (100,000 vs 95,000), runtime (95 vs 75 minutes), waterproofing (IPX-8), and total value (mount and switch included at $399). The OKW v2 wins on modularity (swap heads for different beam profiles), lumen output (1,300 vs 1,250), admin mode, ecosystem breadth (SureFire Scout mount compatibility), and head-only upgrade cost. If you are starting from zero, the REIN 3.0 is a better all-in-one package. If you are already invested in Modlite bodies and mounts, the OKW v2 head upgrade is compelling and inexpensive.

OKW v2 vs SureFire M640DFT Turbo

The M640DFT Turbo matches the REIN 3.0 at 100,000 candela but with only 700 lumens, meaning less total light and less spill. It has the longest runtime in this class at 2.75 hours on 18650 and the smallest form factor. The OKW v2 delivers nearly double the lumens (1,300 vs 700) at 95% of the candela, in the same SureFire Scout mount ecosystem. Both require separate mount and switch purchases. At $309 vs $379, the OKW v2 is the better value unless SureFire brand loyalty or the Turbo's extended runtime is the deciding factor.

The strongest case for the OKW v2 is the shooter who already has a Modlite PLHv2 as their general-purpose light and wants a second head for dedicated long-range identification. Spending $189 on an OKW v2 head to thread onto an existing body is dramatically cheaper than buying a second complete light system. This modularity, combined with SureFire Scout ecosystem compatibility for mounts and switches, makes the OKW v2 the most flexible option in this class.
