The Nitecore Concept 1 is the first in a new range of torches aimed at flashlight enthusiasts, who demand more from their torches than regular users. In other words it has been made for flashaholics like you ;)

Includes free Nitecore IMR18650 3100mAh protected battery with continuous discharge rate of 10A.

Featuring the Cree XHP35 HD E2 LED with a maximum output of 1800 lumens when used with the included high capacity protected IMR battery. This makes it the most powerful single 18650 light we currently sell and it can also run on a pair of CR123A cells.

The Concept One is very small (11.1cm) and light weight (62 grams) making it the perfect every day carry torch. In order to keep size to the minimum Nitecore have continued to innovate with the metal side switch on the side of the head.

Beam distance is impressive at 220 meters aided by the crystal coating technology and precision digital optics reflector. An integrated advanced temperature module (ATR) regulates the brightness to ensure a safe operating temperature to extend the LED life.

A removable pocket clip (screw attachment!) and magnetic tail cap allow for a range of hands free operation.

Two modes of operation are available. To change mode simply turn off the light, loosen the head section half a turn and tighten while holding the side switch. The light will then flash to indicate which mode has been selected, single flash for general mode and double flash for tactical mode.

General mode: Offers direct access to turbo brightness from standby (triple click)
Tactical mode: Offers direct access to strobe from standby (triple click)

Five brightness levels (runtimes using included IMR18650):

Turbo: 1800 Lumens - 30 minute runtime
High: 810 Lumens - 1 hour 30 minute runtime
Medium: 300 Lumens - 4 hour runtime
Low: 80 Lumens - 15 hour runtime
Ultra Low: 1 Lumen - 300 hour runtime

To change brightness simply hold down the side switch with the light turned off and the Concept one will cycle though the modes - release to select desired brightness. An intelligent circuit remembers the last brightness level used.

The Turbo 1800 lumen mode requires the use of IMR18650 or Li-ion 18650 with an output current higher than 8A. When used with batteries with output current lower then 8A the turbo mode will not be available.

Other notable features of the Nitecore Concept 1 include an efficient constant circuit so there is no flicker (PWM). The LED also acts as a volt meter when a battery is inserted by flashing the voltage!

Water proof to IPX8 (2 meters submersible) and impact resistant to drops from up to 1.5 meters. The Nitecore Concept 1 is the light every flashaholic should have in their collection.

Includes: Nitecore IMR 18650 battery, spare o-ring, wrist lanyard, screw on pocket clip, holster.
