The correct question is: what advantages does it offer over a aspheric lens, because optically that is much closer. And the answer is: in this size that is not clear, although it looks like this mirror is optically better than the aspheric lenses commonly used in flashlights.
In larger lights it becomes a major advantage that mirrors are more lightweight than an aspheric lens, and optically superior over a fresnel lens.
But for me it is about the :sunglasses: factor, it is a type of flashlight that I have not fiddled with as yet.
