I'm going to be doing some night rural riding this summer and may need additional illumination. Arrived yesterday and I tested them last night. Not fancy features but the look and feel are quality/fine. I want to make sure its "4000 lumen" claim really is significantly better than my trusty Light & Motion Urban550. If so, it'll be a great deal. That test is probably tonight, though they're probably already impressive anyway to be keepers. (I paid 4X as much for the Urban550 years ago.)
P.S. Speaking of trusty, I still have and use my Blackburn Flea set regularly for just be-seen needs.
