What does a 12,000-lumen flashlight actually look like at night? The Olight X7R Marauder is the brightest light I’ve ever owned.
It’s also the most I’ve ever spent on a flashlight. Here’s the unboxing, the modes and how to use them, and an outdoor night test. The X7R isn’t sold anymore, so the box below links the current Olight Marauder.
- Insanely bright with a huge, wide flood
- Feels great in the hand despite its size
- USB-C charging
- Mode memory and a nightlight mode
- Solid holster and accessories included
- Expensive
- Big and heavy (about Coke-can size)
- Gets hot fast on high
- Not zoomable

What’s in the box
The box has a magnetic closure. Inside is the light, about Coke-can size with real mass and heft, plus a manual, a Velcro holster with a MOLLE/belt strap, a short USB-C cable, a paracord lanyard and a USB charging block.

Build and design
The head has three textured, polished reflectors with four LED elements each, 12 in all, plus a sensor. There’s blue anodized trim around the head and the power button, which sits right under your thumb.
The base twists to open a hatch with a reversible USB-C port. It has fluting, knurling, heatsink fins and finger grooves, and it feels like a block of metal.

How to use the modes
- Unlock: it ships locked; hold the button a couple of seconds.
- On/off: tap. It remembers your last mode.
- Low/medium/high: press and hold to cycle.
- Nightlight: from off, hold more than 1 second.
- Turbo and Turbo S: double-click, then double-click again.
- Strobe: triple-click.
Even indoors, the indirect light burned into my vision, and on high I could feel the heat in my hand almost instantly.

Night test
Outside in a drizzle, even high lit up the grass and trees in the distance, plus about 10 trees on either side of where I was aiming. It felt like stadium lights.
On Turbo a willow far out was totally lit up, and on Turbo S I spotted a skunk way out there and could see its eyes. Even low is better than most flashlights.
Who needs this much light?
Search and rescue, first responders, patrolling a ranch or big property, or checking on cattle or crops. Where most flashlights make a pencil beam, this lights up a huge area.
If I can only take one light, this is the one. It’s like bringing an artificial sun with me.
