Nitecore is continuing to push the boundaries with the Nitecore Concept 1, the first release in the new Concept Series. Featuring a premium CREE XHP35 HD E2 LED for a super bright 1800 lumens max output, the C1 is easily the top of its size class. A conveniently located single side switch control lets users adjust through 5 brightness settings and two selectable operating modes give a choice between direct access to Turbo or Strobe.
Operating on 1x IMR18650 battery (recommended) or 2x CR123A batteries, the C1 offers up to 300 hours of runtime on low and up to 30 minutes on Turbo. The compact 4.39" body tube weighs under 3 ounces without a battery making this flashlight perfect for everyday carry, travel and emergency backup.
The Concept 1 supports multiple battery options including button top & flat top IMR 18650 batteries. For optimal performance and to enable the full 1800 lumen output, we recommend using the button top IMR 18650 provided in the drop down option above (or here) which has a built-in protection circuit. The light will shut off at the maximum setting when using 2xCR123A or an 18650 battery with lower than 8A output.
