I really like this light. While the tint is a bit warmer than the neutral white I prefer, it's a pleasant and easy to look at when your eyes are dilated. One thing I would prefer is a lower low. Medium and high or good output levels, but low could be much lower; something closer to 1 lumen or maybe even a Moonlight mode.
That said, every light is a compromise in size, weight, output and runtime, among other attributes and this light hits enough of them right that it gets 5 stars.
