The Acebeam W50 2.0 isn’t a flashlight you toss in your glovebox. Weighing 3.75 pounds and nearly the size of a thermos, this beast is built for extreme reach, rugged conditions, and serious throw. Thanks to LEP (Laser Excited Phosphor) tech, it can punch a beam over 5 kilometers, or more than 3 miles a feat that even high-end LED flashlights can’t match.
LEP technology pushes flashlight range to new extremes

The W50 2.0 doesn’t care about lumen bragging rights. While it peaks at 1,900 lumens, the beam is hyper-focused, allowing it to slice through darkness farther than most handheld lights. That power comes at a price, though literally and physically.
At nearly 1,660 grams, this is a flashlight best slung over your shoulder or mounted to a tripod. It’s powered by eight internal 18650 cells, sealed inside the housing, and charged via USB-C. No swapping batteries here. While Acebeam hasn’t confirmed full specs for the charging system, it’s likely capped by basic USB-C current unless Power Delivery kicks in.
Not just spotlight: W50 2.0 features zoomable floodlight mode
The W50 2.0 includes a zoom-out mode, shifting the ultra-tight LEP beam into a wider, LED-style spread. In this floodlight setting, it pushes 2,200 lumens across 486 yards still impressive. This mode runs at full power for 5 minutes before throttling to 1,250 lumens for just under 3 hours.
Quick breakdown of flashlight modes:
- Spotlight mode:
- 1,900 lumens → 5 km throw (50 seconds)
- 1,050 lumens → 2:40 hours (range not listed)
- 650 lumens → ~2 miles (sustained use)
- Floodlight mode:
- 2,200 lumens → 486 yards (5 minutes)
- 1,250 lumens → 2:40 hours
Warnings apply: This isn’t a toy
The W50 2.0 uses a Class 3B laser, meaning eye safety is a serious concern. Despite not emitting a visible laser beam, the intensity can cause injury. Acebeam advises caution especially during search and rescue missions, where lighting up vast areas is useful but must be handled responsibly.
Built like a tank, but not built for your belt
The Acebeam W50 2.0 is IP68-rated, tripod-compatible, and ships with a removable carrying handle. It’s about 8.6 inches long with a 3.3-inch head diameter, so storage isn’t exactly convenient. But for those who need absolute range and reliable runtime in tough conditions, this flashlight delivers in ways few others can.
It won’t win any minimalist design awards but when you want your light to reach a mile or three, subtlety isn’t the goal.
