Convoy L21B SFT42R 5000K, 2600 Lumens, 1350m Range

Note: This torch is self assembled with carefully selected parts for the best performance. In stock form they operate at a lower brightness and are usually out of focus. I 3D print my own custom part to fine-tune the focus for max range.
 
This SFT42R LED is an absolute beast, best range and beam width balance I've come across, and in 5000K colour temperature.
