The Weapon Light Brands
Streamlight (24.8%)
The ProTac HL-X at 17.5% is the single most-selected weapon light. 1,000 lumens, a proven pressure pad, and a price under $120 make it the default recommendation. Streamlight has been making professional-grade flashlights for decades.
SureFire (18.3%)
SureFire X300-A Turbo at 5.7% and X400 Ultra at 4.3% represent the duty-grade tier. SureFire lights are issued to military and law enforcement units worldwide. They cost more, but the reliability is unquestioned.
Olight (12.4%)
Olight Odin Mini at 9.0% is their AR15 flagship. Magnetic charging, M-LOK compatibility, and solid output. Olight is controversial in some circles but the sales data shows builders are buying them.
Sightmark (9.1%)
Sightmark LoPro at 7.9% is the budget entry point. Under $50 gets a functional light on your rifle. Not duty-grade, but better than no light.
Cloud Defensive & Modlite (5.8% / 3.9%)
These are the enthusiast brands. Cloud Defensive REIN and Modlite OKW/PLHv2 push candela and throw distance to the extreme. Popular with night vision users and long-range shooters.

How to Choose Your Weapon Light
- Budget (Under $80): Sightmark LoPro or Inforce WMLx. A basic light that covers the essentials.
- Mid-Range ($80-$200): Streamlight ProTac HL-X or Olight Odin Mini. This is where most builders should be. Proven performance, pressure pad included, good output.
- Premium ($200+): SureFire X300/Scout, Cloud Defensive REIN, or Modlite OKW. Duty-grade lights for people who depend on them.
Mount your light on the side of your handguard (9 o'clock for right-handed shooters), not on top. Top-mounting puts the light behind your front sight and creates a shadow. Side-mounting gives a cleaner beam pattern and keeps the top rail free for optics.
