Knog from Australia makes a serious effort in lights with a staggering selection. Honest outputs, good beam patterns and the best form factors in the business are some of its virtues with this 640 as their brightest offering.
The Volt 1600 continues to be one of our favorites as the output bumps up to 1600 Lumens now. Chassis and mount are getting a bit dated now for this much light but this is still a self-contained powerhouse.
This latest Lumina bumps output to an honest 800 Lumens. It also incorporates an OLED display to make switching through modes very easy. Finding out remaining runtime on any light level is handy as well.
