In my opinion it has 1300 lumens, because my fenix with 1000 lumens it is more brighter.
It is a good lamp but it does not reach 300 meters because the light is very wide.
I'm happy with the lamp but you have to work more in the reach of light.
You need to work harder to focus the light. The light can not be so wide if you want to reach 300 m clearly.
I am satisfied with klarus xt11gt, but fenix uc35 with 1000 lumen is the winner, because it reaches 280 meters with better focus.
Thanks
