The Nitecore Concept 2 is a rechargeable unit and the second model in the Concept series. Utilising four Cree XHP35 HD LEDs allows for a maximum output of a whooping 6500 lumens.
Crystal coating technology combined with precision digital optics technology provides extreme reflector performance that enables the beam to reach up to 398 metres.
The Concept 2 has a built-in 12400 mAh battery comprised of four high drain 3100 mAh 18650 lithium-ion cells. The battery is charged via the charging port on the side of the torch. Simply remove the dust cover and insert the included adaptor one end and plug the other into a 3 pin UK main socket. The blue LED indicator under the switch will slowly blink to show charging is in progress and will turn solid blue when charging is complete after approximately 5 hours.
Each time the charging cable is removed the blue LED will report the power status and this can also be done by pressing the button once while the torch is off. The blue LED will flash to indicate the battery voltage, so for example if it is fully charged to 4.2 V, the light will flash four times, pause and then flash two more times.
The Concept 2 is operated using the side mounted two stage switch. Fully press the button until a click is heard to turn the light on or off. Once the light is on soft half presses of the button will cycle through ultralow, low, mid, high, turbo and the last used brightness setting will be remembered next time you turn the light on.
Instant access to turbo is possible by fully pressing and holding the button while the torch is off and once you release the button the light will go off or half pressing and holding the button while the torch is on and once you release the button it will go back to the previous brightness setting. The special modes are accessed by fully pressing and holding the button while the torch is on until it enters strobe. The button can then be released and half presses cycle through beacon, SOS and strobe.
A lockout function prevents the torch from being activated in transit and is recommended when it is in a backpack or anywhere the button may be presses accidentally. To enter lockout mode firstly turn the light off and then half press and hold the button for 2 seconds until the main LED flashes once to notify users that lockout mode has been entered. To exit lockout mode fully press and hold the button for 2 seconds until the light turns on.
The advanced temperature regulation module allows the concept 2 to regulate its output and adapt to the ambient environment to maintain optimal performance.
The lack of a tail switch means the Concept 2 can stand securely on it's end to serve as a candle light. A lanyard, holster and pocket clip are all included for easy and versatile carrying options.

Turbo: 6500 lumens; 30 minutes run-time; 398 m beam range*
High: 2500 lumens; 1 hour, 30 minutes run-time; 252 m beam range*
Mid: 1000 lumens; 6 hours, 30 minutes run-time; 155 m beam range
Low: 285 lumens; 16 hours run-time;77 m beam range
Ultra-low: 1 lumen; 2000 hours run-time; 5 m beam range
Special Modes: 6500 lumens
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. The head of the torch rapidly generates heat when in turbo and high settings, adjust the brightness manually if the torch is too hot to handle.
