Not tested outside yet but look to be high quality and shines like hell. Both 1600 and 800 lm regimes are significantly brighter than my older 500 lm light, so I guess the numbers are true. I just hope that it will not lose power over time as my other light does and stay at full power for the stated time. The quality of the bracket also looks pretty good and it should be sturdy enough. There's also a wired remote that I won't be using as I don't want to clutter my cockpit that much with more wires and I probably won't need to change the power of the light that often. It, however, may be very useful for a road cyclist that needs to change the power based on the oncoming traffic or so. Looking forward to taking the light out in the woods for a ride.
Fast shipping. Perfect packaging.
