nitecore

As the name might suggest, Nitecore's line of Tiny Monster flashlights are design to pack maximum punch into compact packages, and the recently introduced TM20K cranks up the illumination to a blinding 20,000 lumens.

In 2013, Nitecore introduced what it billed as the world's smallest 3,500-lumen flashlight. After eight years, it's managed to shrink the size of its lights much further, packing 4,000 lumens into a torch that hangs from a keychain.
