Nitecore C1 Concept 1 Series LED Flashlight
Key Features
  • 1 / 80 / 300 / 810 / 1800 Lumens
  • Cree XHP35 HD E2 LED
  • Strobe, SOS and Beacon Modes
  • Side Switch
Offering extraordinary output for its size, the Nitecore Concept 1 Flashlight performs like a full-size torch, yet takes up barely any space and weighs just over 2 ounces. Its top setting is a blazing 1800 lumens, and it will run on its lowest setting for 300 hours on one rechargeable 18650 battery. The single metal side switch provides access to five output levels plus disorientating strobe and a location beacon. In General mode, three taps of the switch takes you straight to turbo, while in tactical mode, the same three taps activates the strobe. The C1's beam is smooth and steady thanks to its constant current circuit technology, which avoids the flicker often experienced with lights using pulse width management (PWM).

Nitecore Concept 1 Overview

Offering extraordinary output for its size, the Nitecore Concept 1 Flashlight performs like a full-size torch, yet takes up barely any space and weighs just over 2 ounces. Its top setting is a blazing 1800 lumens, and it will run on its lowest setting for 300 hours on one rechargeable 18650 battery. The single metal side switch provides access to five output levels plus disorientating strobe and a location beacon. In General mode, three taps of the switch takes you straight to turbo, while in tactical mode, the same three taps activates the strobe. The C1's beam is smooth and steady thanks to its constant current circuit technology, which avoids the flicker often experienced with lights using pulse width management (PWM).

The LED serves as a battery power indicator, reporting voltage with a series of blinks each time a battery is inserted, so you won't be caught off-guard by a depleted cell. As you might expect with such a high-powered light, there is protection from overheating in the form of Nitecore's Advanced Temperature Regulation feature, which maintains stable performance and extends the light's lifespan.

A magnetic tailcap allows the light to be attached to any metal surface for hands-free use, and the stainless steel clip assures is stays put in your pocket or pack. Rated IPX8, the C1 is submersible to 6.6' and impact-resistant to 4.9'. It can be powered by one 18650 or IMR18650 or two CR123 batteries.

Nitecore Concept 1 Flashlight

By Dale
Rated 1 out of 5

This flashlight will likely cost you $120 instead of $61, unless you already have the NL1835HP 8 Amp batteries. Nowhere in the manual is this requirement stated, nor in the product information here including the tech specs. But when you receive the C1, the Quick Start Guide tells you that the C1 will Turn on and turn back off immediately if you do not have the 8 Amp batteries. The 8 A is printed right on the batteries.
