Black Eye X31 is an advanced handheld flashlight designed for users requiring maximum light range and precise control. It emits a beam of 3100 lumens with an impressive range of 530 meters, making it the farthest shining model in the Black Eye series. It is a reliable tool for uniformed services, rescuers, military personnel, and professionals working in demanding conditions.

QUICK-SET™ Programming – Full control over light
Thanks to the advanced programming system, the user can adjust the modes to specific operational conditions.
- Program 1 offers five brightness levels that allow precise management of the light beam and runtime.
- The Boost mode delivers 3100 lumens, providing a strong light beam and a range of up to 530 meters, which is crucial in situations requiring long-distance lighting.
- The High and Medium modes allow for optimal adjustment of light intensity for prolonged activities, ensuring a balance between power and extended runtime.
- The Low modes guarantee energy savings while maintaining lighting functionality in less demanding conditions.
Ultra-Energy Saving Mode – SURVIVAL
The Black Eye X31 is equipped with a Survival mode that allows operation for up to 4 days, providing minimal but sufficient lighting for survival in crisis situations. This feature is extremely useful for rescuers, soldiers, and individuals exploring hard-to-reach areas where a reliable light source can determine safety and survival. The Survival mode can be activated by holding the button when the flashlight is off.
Program 2 – Advanced Dimming System
The flashlight also offers Program 2, the Advanced Dimming System, which allows for smooth brightness adjustment. Thanks to this feature, the user can precisely adjust the light intensity to current conditions, which is ideal in situations requiring dynamic changes in lighting levels. This is particularly effective during tactical operations, terrain exploration, searches, and activities in changing weather conditions.


Strobe & Beacon – Effective signaling in emergencies
The Black Eye X31 is equipped with the Strobe & Beacon function, which allows for instant switching between strobe mode and BEACON mode by double-pressing the button. The Strobe mode is effective in disorienting opponents and providing warning signals, while the Beacon mode allows for signaling one's position in emergencies, which is extremely important during rescue operations, military operations, and survival situations.
Last Setting Memory
The Black Eye X31 flashlight is equipped with the Last Setting Memory function, which remembers the last used lighting mode. This allows the user to quickly return to their preferred setting without the need to reconfigure the modes after turning it back on. This convenience increases comfort and efficiency of use, especially during dynamic field operations.
Durability and resistance in extreme conditions
The sturdy housing made of aircraft-grade aluminum provides high resistance to mechanical damage, and the IPX8 rating guarantees complete waterproofing, allowing operation in the most challenging weather and terrain conditions. The flashlight is resistant to drops from a height of 1 meter, making it ideal for dynamic operational and field activities. Powered by a 21700 battery with a capacity of 5000 mAh, it allows for up to 4 days of operation in Survival mode, and the USB-C port enables fast and convenient charging. Included with the flashlight is a reduction sleeve that allows the use of popular 18650 batteries. The built-in battery level indicator ensures full control over energy levels, which is crucial during prolonged missions.
Adaptive Cooling Technology – Overheat protection
The built-in Adaptive Cooling Technology system automatically monitors and regulates the temperature of the electronics controlling the LED, preventing overheating of the components. This solution ensures stable and long-lasting operation of the flashlight, even in demanding operational conditions.
