The Nitecore EDC27 UHi is an ultra-slim, high-performance tactical Everyday Carry (EDC) flashlight, serving as an updated version of the popular EDC27. It's designed for discreet pocket carry while still delivering powerful illumination for various situations, from daily tasks to tactical applications.
Key Features
Ultra-Slim and Flat Design: The defining characteristic of the EDC27 UHi is its incredibly slender profile, measuring only 14.2mm (0.56 inches) in thickness. This flat design makes it exceptionally easy to slip into a pocket, backpack, or even a shirt pocket without creating bulk.
NiteLab UHi 20 LEDs: It utilizes two NiteLab UHi 20 LEDs, which are Nitecore's proprietary, purpose-built LEDs featuring a round light-emitting surface. This design enhances optical efficiency, resulting in a cleaner beam and impressive throw for its size.
High Output and Throw:
It boasts a maximum output of 3,100 lumens, providing a powerful burst of light.
The beam can reach up to 305 meters (333 yards), allowing for good visibility at a distance despite its flood-oriented nature.
Tactical Tail Switch System: The EDC27 UHi features a sophisticated two-stage tactical tail switch designed for rapid and intuitive operation:
Power Button (Taller): A full press for constant on/off. A half-press cycles through standard brightness levels (Ultralow, Low, Mid, High). A half-press and hold from off gives momentary Ultralow.
Mode Button (Flatter Paddle): A half-press and hold for momentary Turbo (3,100 lumens). A full press and hold for momentary Strobe (3,100 lumens). The Strobe mode uses randomly changing frequencies for a more disorienting effect. This "STROBE READY™" technology ensures quick access for self-defense or signaling.
OLED Real-time Display: A clear OLED screen on the side of the flashlight provides real-time information at a glance, including:
Current brightness level (lumens)
Battery voltage
Estimated remaining runtime
Lockout mode status
Internal temperature
Built-in Rechargeable Battery: It's powered by an integrated 1,700mAh Li-ion battery, which contributes to its compact dimensions.
USB-C Rechargeable: The flashlight features a convenient USB-C charging port, allowing for fast and efficient recharging. A full charge generally takes about 1 hour 15 minutes with a compatible 5V/2A adapter.
Advanced Safety and Durability:
Rapid Lock™ System: A physical sliding lock switch on the tailcap offers two modes to prevent accidental activation: Semi Lockout (disables constant-on but allows momentary Turbo/Strobe) and Full Lockout (disables all functions).
Durable Construction: The body is made from high-strength stainless steel with a PVD (Physical Vapor Deposition) titanium coating, offering excellent resistance to scratches, wear, and corrosion. It often incorporates a carbon fiber reinforced polymer frame for lightweight rigidity.
Advanced Temperature Regulation (ATR): This patented technology monitors the internal temperature and adjusts output accordingly to prevent overheating and maintain optimal performance.
IP54 Rating: It is rated IP54 for dust and water resistance, protecting it from splashes and light rain.
Impact Resistance: Withstands impacts from up to 1 meter.
Sensor Protection Function: Automatically reduces brightness if the light is accidentally turned on while obstructed (e.g., in a pocket) in High, Turbo, or Strobe modes to prevent overheating.
