Nitecore Concept C1 Flashlight - 1800 Lumens

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.

The 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 a pocket or backpack.

Concept 1 uses a CREE XHP35 HD E2 LED, integrated with the CREE breakthrough technology SC5 to greatly improve 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.

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

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

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

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

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.
