The Nitecore i4000R is the latest of the next generation 21700 lights from Nitecore. Featuring 4 x Cree XP-L2 V6 LEDs the i4000R has a maximum brightness of 4400 lumens in a torch that can easily fit inside a pocket.

The i4000R is rechargeable and includes a patented 5000mAh 21700 battery, which has positive and negative polarities at both ends to help minimise the loss of power due to internal resistance. The battery charges inside the torch via a USB-C port in the tail cap, which has a rotatable protective cover made from aluminium alloy. A USB-C charging lead is also included.

This light can be used for a wide variety of applications with the added benefit of Nitecore's 2nd generation strobe ready technology. With the light turned off the mode button provides instant access to the strobe setting making this an ideal companion when alone at night. Strobe can also be accessed when the light is turned on by triple clicking the mode button. For normal operation there is a tactical tail switch with momentary on function and then the mode button cycles through the brightness levels and pressing and holding provides access to the turbo mode of 4400 lumens.

ATR (Advanced Temperature Regulation) regulates the output of the i4000r according to the working condition and ambient environment to maintain optimal performance and prevents damage to the LED from overheating.

The Nitecore i4000R is very compact for a torch of this brightness and the 1 inch diameter body is compatible with a wide range of mounting systems. Also included is a Nitecore NTH20 holster, which can attach to a belt or Molle webbing.

In addition to the rechargeable 21700 battery the i4000R can run on CR123A cells with the provided battery magazine, although runtimes will be much lower when used with these types of battery.

Water resistant to IP68 and resistant to drops from up to 1 meter.

Nitecore i4000R includes: Nitecore NL2150HPi 5000mAh 21700 li-ion battery, USB-C charging cable, pocket clip, wrist lanyard, spare o-ring, CR123 battery magazine and NTH20 tactical holster.
