Top Rifle Lights Ranked by Data

1. Cloud Defensive Rein — Best Overall

The Cloud Defensive Rein has taken the rifle light market by storm with 166 average upvotes — the highest engagement of any rifle light. The Rein 2.0 complete kit includes the light head, body, rechargeable 18650 battery, tape switch, and all mounting hardware. No piecemeal buying required. Output is exceptional with both high candela (throw) and healthy spill for indoor use.

Pros: Complete kit, outstanding output, excellent tape switch, bombproof build quality.
Cons: Slightly heavier than scout-pattern lights, proprietary form factor.

2. Modlite PLHv2 / OKW — Best Premium Output

Modlite set the standard for high-output rifle lights. The PLHv2 head is the balanced choice — excellent throw with good spill for general use. The OKW head is a throw monster designed for reaching out to 300+ yards. Both use interchangeable heads on the same 18650 body, so you can swap between profiles. Modlite bodies accept SureFire-pattern tape switches.

Pros: Best-in-class output, interchangeable heads, SureFire tail cap compatibility.
Cons: Need to buy body + head + switch separately, premium total cost.

3. Streamlight ProTac HLX — Best Budget

The Streamlight ProTac HLX (also known as the HL-X) is the budget rifle light champion. At 1,000 lumens with an included tape switch and mounting hardware, it's a complete package under $70. The "Great" price tier occasionally shows absurdly low prices during holiday sales and bundle deals. It runs on either two CR123 batteries or one rechargeable 18650.

Pros: Complete package with tape switch, 1,000 lumens, proven reliability, insane value.
Cons: Lower candela than premium options, tape switch is decent but not Cloud Defensive quality.

4. Arisaka 300/600 Series — Best Scout-Pattern

Arisaka builds clean, efficient scout-pattern lights using Malkoff heads. The 600 series (18650 body) is the full-power option, while the 300 series (18350 body) saves weight and length. Both accept Malkoff and Arisaka heads in various beam profiles. The build quality is exceptional — machined aluminum with excellent anodizing.

Pros: Compact scout pattern, multiple head options, excellent build quality, lightweight.
Cons: Lower output than Cloud Defensive/Modlite, limited deal data.

5. SureFire Scout M600 — The Original

SureFire's Scout series (M600/M640) defined the scout-pattern rifle light. Built to military specs with a proven track record in actual combat. The M600DF runs on an 18650 and puts out 1,500 lumens. The newer M640 series is a more modern update. SureFire compatibility means the widest selection of tape switches and mounts.

Pros: Military-proven, widest accessory ecosystem, bombproof reliability.
Cons: Premium pricing, newer competitors often outperform on candela.

Tape Switches and Mounts — Don't Overlook These

A rifle light is only as good as its activation method and mounting. Key considerations:

• Tape switches: Cloud Defensive's REIN switch is the best in the business. For SureFire-pattern lights, the Modlite ModButton or Unity TAPS are top choices.
• Mounts: Arisaka inline and offset mounts are the gold standard for scout-pattern lights. They come in M-LOK and KeyMod variants.
• Positioning: Mount the light as far forward as practical, on the support-hand side for thumb activation. Avoid mounting on the top rail where it blocks your sight picture.
