What's the difference between the Nitecore TM39 Lite and Nitecore TM39?
Easy, it's the form factor and power source. The TM39 Lite runs off of high powered 18650 batteries and has a smaller, more compact, and lightweight design. And you still get the best features that the full-sized version has to offer, like an intuitive dual button user interface for single-handed use and an integrated OLED that feeds you real-time information like remaining runtime, output, and battery level. Plus, you get the same 5200 lumen output as the full-sized version, but at half of the size!
