Utilizing 4 x CREE XP-L2 V6 LEDs and a total reflective optic lens for uniform and soft light, the newly released NITECORE T4K has a max output of 4,000 lumens, a max peak beam intensity of 10,900cd and a max throw of 209 meters. As a thumb-sized technical breakthrough, the spatial distribution is precisely calculated so that the electronic components including the OLED display, quad-core emitters and dual switches can be packed in an ultra compact housing to offer an unprecedented user experience.

The multifunctional OLED real-time display is always ready to show the current flashlight status including battery level & voltage, brightness level, current user mode, and runtime remaining. Also inherited from the NITECORE Flagship Product TM10K, the T4K is available for two different levels of lockout modes for various storage, daily or emergency needs.

The T4K has an ultra compact and lightweight body of 77g (2.72oz) with the versatile Deep Carry Pocket (DCP) Clip. The Mechanical Quick Release Design enables you to hold the Quick Release Button and pull out to conveniently detach the keychain light. The solid metallic ring pull is able to withstand up to 30kg (66lbs) of weight.

The Advanced Power Cut-Off (APC) Technology allows an ultra-low standby current of 1μA provides a unique and unprecedented user experience in the standby status. The built-in Li-ion battery of 1,000mAh offers a runtime up to 67 hours. The multiple USB-C charging safeguards ensures a safe charging process. The integrated ATR technology regulates the output of the T4K according to the working condition and ambient environment to maintain the optimal performance. The quad-core emitters are embedded on the 3mm-thick copper cooling PCB, designed to make the heat quickly dissipated in order to guarantee a stable performance.

The T4K has 2 user modes and 5 brightness levels available for various scenarios. Direct access to TURBO is available for outdoor and long-range searching while ULTRALOW can be used for short-range illumination to protect the scotopic vision. It is continuously powered even in the charging status for users to get out of the outdoor illuminating predicament and enjoy the inexhaustible power supply.
