X850 Flashlight Kit

The X850 is your go-to lightweight workhorse. We took our reliable X800 and squeezed out an extra 50 lumens — all without adding bulk. It’s designed for helmet mounting, everyday use, and those times when you want a powerful beam without carrying a torch. Kept rugged, kept simple, built to serve.

Why We Built It

• Weight & mounting priority: We heard from riders — “give me brightness, but don’t make me carry a tank on my helmet.” So the X850 sits in the sweet spot: light enough for helmet mounting, yet powerful enough for real tasks.

• Incremental upgrade over X800: Rather than reinvent, we refined — 50 more lumens in the same rugged chassis, delivering better output without compromising balance or durability.

• Versatility in mounting: Comes with both helmet and handlebar mounts out of the box, so you don’t need to pick or compromise your mounting style.

• Modern charging & resilience: Upgraded to USB-C so charging is easier and more universal. Sealed and rated IPX6 for real-world spray and weather.

Testing & Real-Use Scenarios

• Night rides & trail work: We’ve mounted this light on helmets during late-night runs, mapping terrain, spotting ice, and navigating unlit stretches. The X850’s balance lets you forget it’s there until you need it.

• Cold & wet exposure: Exposed to snow, rain, and freezing spray — seals held, brightness remained stable, and the USB-C charging stayed reliable in damp, dirty conditions.

• Crash & vibration tolerance: Through off-trail bounces, minor tumbles, and trail chatter, we confirmed the housing and mounts keep the light locked in and functioning.

• Battery consistency: Multiple full-discharge cycles in cold temperatures — wattage drop and warm-up behavior were monitored to ensure usable output under real alpine conditions.

When You’ll Get Full Value Out of It

• Helmet-first riders: If your go-to mounting is your helmet, this light’s weight, beam pattern, and mounting logic make it an ideal fit.

• Utility over range: When you need brighter fill than a headlamp but don’t need a 2,000-lumen throw, this is the sweet spot.

• Multi-mount flexibility: You want one light for both vehicle and helmet use without buying extras.

• Day-to-night usage: Because of its efficient lower modes, you can use it during twilight, transition zones, or around camp without burning battery in full mode.

• Gear minimalists: When weight and simplicity matter, this is a high-output tool that doesn’t complicate your kit.
