Maybe not, but they're the same exact driver and the same light pattern as the MagicShine, and most other "proper bike lights." I'm not sure what in your mind makes something a "proper bike light" unless it's just that it was designed as a bike light, rather than how it performs.
I can't tell if I've got the MagicShine or the flashlight turned on when I'm riding unless I look at the bar to see which one is on.
If a flashlight meets your runtime requirements, they're every bit as good a bike light as anything you could buy up to about 3 years ago, and they cost less than "proper bike lights" that put out 1/5 as much light.
