Amazing light. I got two of them to mount one on a handlebar and one on the helmet. Just one light is not enough for riding MTB single-track in the dark... but do not get me wrong... even one 3000 - 5000 lm won't be enough because the beam is not covering wide enough area and I do not like the idea of remote power bar on more powerful bike lights. two lights setup works great even on 600lm settings for most of the riding, full 1200lm are great when trail gets very gnarly. The lowest setting is enough to ride any access road in complete darkness to the main trail. On the photo I am running only one light on the handle bar.
