Nitecore EC23

The Nitecore EC23 torch has a maximum output of 1800 lumens from the Cree XHP35 HD E2 LED and can be powered by either 1 x 18650 (output ≥ 8A) battery or 2 x CR123 single use or RCR123 Li-ion batteries.

Please note: The EC23 can be powered by an 18650 battery, however it MUST have an output of 8A or higher.

With an excellent output and throw, the EC23 is an ideal flashlight for everyday carry. The EC23 feature five brightness levels ranging from 1 to 1800 lumens, in addition to strobe, SOS and location beacon modes. The settings are controlled by an all-in-one side switch, providing convenient operation. 
The Nitecore EC23 has a blue power indicator built into the side switch which reports remaining power level. This ensures you know when the battery needs charging or changing to provide you with enough power for your application.
The flashlight is made from high quality materials and features a diamond knurled body for a comfortable, anti-slip grip.
