There's much better options - SureFire Tactical Helmet LED Light/Military Helmet Mount Flashlight

The light itself is OK. The switches are intuitive and easy to flip with gloves. That said, the output is underwhelming, especially at this price point. Now here's where things really suck. The mount. Absolute garbage and outdated. It may have worked, OK, with a Mich, but the era of high cut helmets is here, and these haven't changed with the times. There's only one adaptor for a high cut helmet, and it's only for Ops Cores Arc rails. Can I at least get an M-Lok??? Anyway, the mount is garbage, and there's much better, cheaper options out there. It this works for you, cool, for me, it didn't. It's too expensive for what you get. Should have gone with Princeton... I would pass if you're on the fence. I'll be purchasing another light for my helmet. Maybe use this on my plate carrier, but then I have to buy an adaptor for that! Nickel and diming me, Surefire!
