Nitecore TM10K

Compact size, high-tech features, sleek modern styling, and powerful output—the Nitecore TM10K Rechargeable LED Flashlight checks all the boxes for form and performance. Powered by a built-in 4800mAh 21700 battery, the TM10K runs six Cree XHP35 HD LEDs and is engineered to dissipate their heat via a 4mm copper printed circuit board and a die-cast unibody cooling tube. The light is operated by side push-button switches for power and mode and a tail switch for instant access to turbo. The high power setting can be customized at anywhere from 400 to 2000 lumens in 100-lumen increments.

An OLED display shows battery voltage, remaining runtime, light temperature, and turbo duration (the 10,000-lumen turbo mode is meant for burst-style use and limited to 7 seconds’ runtime.) There are two lockout modes: full, for when you’re tossing the light in a backpack and don’t want it to activate accidentally; and half, which leaves the tail turbo switch operational for pocket or holster transport when the light might be needed quickly. A blinking blue indicator beacon on the tail helps you find the light in the dark. The TM10K measures 4.3 x 1.6 x 1.2″ and weighs 8.7 ounces.
