Design & Build Quality#
The SC31 Pro is built from aircraft-grade 6061 aluminum alloy with aggressive knurling that provides excellent grip even with wet or gloved hands. At just 4.6 inches long and 2 ounces without the battery, it disappears into a jeans pocket or clips securely to a bag strap with the included pocket clip.
The side switch sits flush with the body and provides positive tactile feedback without being easy to accidentally activate. A small LED indicator around the switch shows charging status — red while charging, green when full. The magnetic tailcap is strong enough to hold the light on a car hood or metal beam without sliding.
Key Features#
2000 Lumens of Pocket-Sized Power#
The SST40 LED emitter pushes 2000 lumens at turbo — enough to light up a backyard or illuminate a trail 200 meters ahead. That is roughly twice the output of most $20-30 flashlights. The smooth reflector produces a focused hotspot with useful spill, making it effective for both distance and close-up work. At medium settings, the SC31 Pro runs for hours on a single charge without generating uncomfortable heat.
Anduril 2 Firmware#
This is the same open-source firmware found on flashlights costing $80-120. In simple mode, you get on/off, smooth brightness ramping, and turbo. Switch to advanced mode and you unlock stepped ramping, configurable brightness floors and ceilings, candle flicker simulation, lightning storm mode, and even a thermal calibration tool. The learning curve takes about 15 minutes, but once you understand the click patterns, the control feels intuitive.
USB-C Rechargeable#
The built-in USB-C port eliminates the need for an external battery charger. Plug in any USB-C cable from your phone charger, laptop, or car adapter and the included 18650 battery charges safely with overcharge protection. The rubber port cover keeps dust and water out during use.
IPX8 Waterproof Construction#
Rated for submersion up to 2 meters, the SC31 Pro handles rain, snow, mud, and accidental drops into puddles without issue. The aluminum body also serves as an effective heat sink, managing thermal output during extended high-brightness use with automatic stepdown to protect the LED and battery.

Final Verdict#
Buy it. The Sofirn SC31 Pro is the rare budget flashlight that flashlight enthusiasts actually recommend to each other, delivering premium firmware, solid build quality, and serious output at a price that makes premium brands look overpriced.
Our recommendation: Grab one for your EDC and a second for your car or toolbox. At this price, two SC31 Pros cost less than a single comparable Olight or Fenix light. 🇺🇸 Sofirn SC31 Pro on Amazon US | 🇩🇪 Sofirn SC31 Pro on Amazon DE
