    Took this light with me on a 7 day bike tour. I ended up doing several after sunset rides (to get dinner usually, or due to not riding as fast as expected). This thing is killer. I have lower powered Serfas lights, and one thing that was totally unexpected is that the “low” setting on this lamp is like 700 lumens, which is just as bright as my other headlamp. BUT because it’s “low”, it lasts for like 4.5 hours. That’s amazing.

    SO — pick the lumens you want, then buy a light that has that setting as the ‘low’ not the ‘high’ setting. Then you’ll be good to go for extended periods of time.

    This light let me traverse forest gravel trails hours after sunset with no problem. It was able to keep 2 riders safely away from obstacles and navigating without issue. Thanks!

    Just wanted to update my previous review (feel free to post this or just update the previous). I had the lumens for the ‘low’ setting incorrect, but the idea is the same. The ‘medium’ is actually 400 lumens, which is plenty bright for many situations and gives 4.5 hours of runtime. ‘low’ is 200 lumens and 9.5 hours of runtime, which is also great.
