I don't really know about the Sofirn (or any hand torch adapted for bike light use), but if you're considering the the RN-1500, you can get an
RN-3000 (basically 2 RN-1500's side by side in the same case) from AliExpress for not much more. The RN-3000 puts out plenty of light and has really good battery life, but is pretty heavy - so really only good as a bar light.
Tangentially related comment: I'm a believer in bright flashing lights to increase visibility during daylight road cycling. So I have a 250 lumen rear flasher and like as bright a front flasher as I can get. Many lights have a degree of restraint built into their flashing modes and don't flash at full power. The RN-3000 is not so encumbered and blasts out all 3000 lumen in day flash mode. It's a good MTB bar light (though I prefer some others), but it's absolutely my favorite for daylight road rides.
