I am pushing the Chinese clones flashlilghts, they really overstate the lums. .. With that said, the one above might be rated at 1300 lums. I think it is an honest 900 to 1000 lums, and plenty bright. In addition, that photo I was just testing it, I always run in pairs, and since it is getting dark early, one on my helmet too. Also, I am running cheap blinking light strips on my legs..
