Pioneer Design

As the flagship product series of Nitecore flashlights, the Concept Series combines the revolutionary performance with innovative design, intending to make a breakthrough in current illumination industry and bring a brand new illumination experience to users.

Extremely Small and Lightweight

Concept 1 is small and exquisite with 2.18oz weight and 111.5mm length, the size is as small as a 18650 battery, thus it is easy to put into pocket or packsack.

Extremely Powerful CREE XHP35 HD E2 LED

Concept 1 uses a CREE XHP35 HD E2 LED, integrated with the CREE breakthrough technology SC5 to greatly improved the light condensation by up to more than 50% in beam intensity, emitting 1800 scorching lumens, which enables the output of Concept 1 much more stronger than other flashlights powered by one 18650 battery.

    Five Brightness Levels

  • 1800 Lumen - Turbo
  • 810 Lumen - High
  • 300 Lumen - Mid
  • 80 Lumen - Low
  • 1 Lumen - UltraLow
  • Three Special Modes

  • Strobe
  • S.O.S.
  • Location Beacon

Intelligent High-Power Circuit

Built-in high power circuit, driving LED to emit 1800 scorching lumens, giving full play of CREE XHP35 HD E2 LED.

Compact Construction to Minimize the Size

Embedded compact intelligent circuit and outer side switch to spare room of inner space, minimizing the size of Concept 1.

Beam Distance up to Two Hundred Twenty Meters

Crystal Coating Technology combined with PDOT (Precision Digital Optics Technology) for extreme reflector performance.

Integrated ATR Module

The Concept 1 integrated with Advanced Temperature Regulation module to regulate its output and adapt to the ambient environment, maintaining stable performance, extending lifespan.

Multiple Ways of Placement Keep Your Hands Free

Stainless steel clip provides various carrying options Magnetic tailcap can be attached to metal surface with stand capability.

Two Modes Selectable

General Mode: Tap the side switch 3 time quickly to enter Turbo from Standby

Tactical Mode: Tap the side switch 3 times quickly to enter Strobe from Standby

Uses High Efficient Constant Circuit (Non PWM)

Constant lighting without flicker to relieve visual fatigue

The LED Doubles as a Power Indicator to Inform Battery Levels Anywhere Anytime

When power is off, every time the battery is inserted, the light will report battery voltage (to the nearest ±0.1V). For example, when the battery voltage is at a maximum charge of 4.2V , the power indicator will blink 4 times, followed by a one second pause and 2 more blinks before entering the standby status. Different voltages represent the corresponding remaining battery power levels.
