The Nitecore Concept 1 is the first torch in the Concept series. Utilising a Cree XHP35 HD E2 LED it has a maximum output of 1800 lumens.
The included IMR battery has a high discharge current of 10 A to drive the LED to the fullest and incorporates a protection module for added safety. We recommend to charge the battery with a Nitecore battery charger that is designed for IMR batteries to ensure compatibility. A standard 18650 can also be used, however it needs to have a high discharge current of at least 8 A in order to work. The Concept 1 can also use CR123A lithium metal non rechargeable batteries, however the turbo setting is unavailable if you are using CR123A batteries.
Crystal coating technology combined with precision digital optics technology provides extreme reflector performance that enables the beam to reach up to 220 metres.
The Concept 1 is operated using the side mounted switch and has a choice of two modes. General mode offers direct access to turbo from standby and tactical mode offers direct access to strobe from standby. To change modes, turn the light off and loosen the tail cap and then hold down the button as you tighten the tail cap again. A single blink will indicate general mode and two blinks will indicate tactical mode.
All five brightness settings are available in both modes and the last brightness setting used will be remembered next time you use the torch. From off, hold the button down to turn the light on in the previous used brightness setting, or continue to hold the button down to cycle through ultra-low, low, mid, high, turbo. Once you release the button it will select the brightness setting.
From standby two quick presses of the button will enter ultra-low and three quick presses will enter instant turbo or strobe depending on what mode the torch is in. When the light is on in any mode, press and hold the button to momentarily enter turbo and release to go back to the previous output.
The special modes are accessed by triple pressing the button with the light on, or with the light off when set to tactical mode. Strobe will come on first and then to switch between strobe, SOS and Beacon press and hold the button for 1 second. When not in use it is advised to loosen the tail cap half a turn to prevent accidental activation of the button.
The advance temperature regulation (ATR) technology allows the Concept 1 to dynamically adjust output performance based on the internal temperature of the torch in order to protect the LED from overheating and prolong its working life.
A voltage power indicator light is beneath the side switch and will display the voltage each time the battery is inserted. The light will flash to show the voltage, for example if the voltage is 4.2 V the light will flash four times, pause and then flash two more times.
This pocket sized torch can easily be carries with the stainless steel pocket clip and it can be used hands free with the magnetic base.

Using 1 x IMR18650 3100 mAh lithium-ion battery:
Turbo: 1800 lumens; 30 minutes run-time* (turbo not available when using CR123A batteries)
High: 810 lumens; 1 hour, 30 minutes run-time*
Mid: 300 lumens; 4 hours run-time
Low: 80 lumens; 15 hours run-time
Ultra-low: 1 lumen; 300 hours run-time
Using 2 x CR123A 1700 mAh lithium metal batteries:
High: 810 lumens; 1 hour, 15 minutes run-time*
Mid: 300 lumens; 3 hours, 30 minutes run-time
Low: 80 lumens; 13 hours run-time
Ultra-low: 1 lumen; 200 hours run-time
Please note: * The built-in temperature regulation automatically monitors the internal temperature when in turbo and high brightness settings and will lower the lumen output if the torch overheats. Therefore the Turbo mode is unavailable whilst the torch is too hot.
Tested to ANSI/NEMA FL1 standards. Data may vary slightly during real-world use due to battery, individual usage habits and environmental factors.
