Love the lighthead, always ride with the flashmode during the daytime for peace of mind so cars can see me when I'm out riding urban or country roads. Night time could be a bit brighter but still pretty decent for commuting at night as long as there are some random streetlights around.
Love how bright and noticeable this light is on my bike. I have it in the hanging position to get it out of the way. So far I have only used it on the intermittent flash mode. Battery lasts a long time before it needs to be recharged.
