"I was looking for a light that would give me good vision at night and did not need a battery pack. This fits the bill perfectly. It is very bright and lights up the path nicely. Night quite as good as some of the more expensive ones, but then again it is 1/3 the price.
It is a bit on the large side, but I hang it upside down on my handlebars where you barely see it and it also does not have the gear cables to contend with."
