I don't have experience with their bike light, but I bought their HL60R headlamp couple of weeks ago and took it on a ride with my NiteRider Lumina 750. Both Fenix lights use the same LED diode and battery and weigh pretty much the same. What I found is that the Fenix light was as bright as my NiteRider Lumina 750, and cast a much wider beam. Not sure if the bike light version is as wide, but I enjoyed the wider beam while riding offtrail.
