The best combination of light and size that I have


Great product!



Fantastic.. Didn't show mood until I'd charged it (which it states in the instructions). Good quality



My second TM03 to purchase, for me the plus factor is the small size, and extremely bright light


The Nitecore TM03 flashlight has a maximum output of 2800 lumens in burst mode from the Cree XHP70 LED, making it the most powerful single 18650 cell flashlight in the world today. A deep textured reflector ensures a uniform beam pattern with a range of up to 289 meters.

The TM03 has four brightness levels that can easily be cycled through using the Mode switch. The torch has a dual-switch tail cap, allowing for tactical, easy application and direct access to Strobe mode and Burst.

The flashlight has a power indicator LED hidden in the tail switch, which allows you to check the battery has enough power before going out and using the torch.

The included IMR battery is specially made for the TM03 and is capable of providing high output power to drive the LED to the fullest and incorporates a protection module for added safety. We recommend to charge the battery with a Nitecore charger to ensure compatibility.

The TM03 also features temperature regulation and protection. It is able to detect the body temperature and adjust the output performance in real time.

Brightness Levels & Runtimes:

Burst: 2800 lumens 
High: 1350 lumens - 45 mins runtime
Medium: 550 lumens - 2 hrs 15 mins runtime
Low: 40 lumens - 30 hrs runtime

Maximum beam distance 289 meters, waterproof to IPX-8 (2 meters submersible) and resistant to impacts from up to 1.5 meters.
