As compared to the Cateye headlights I've bought, this light falls short.
Yes, it DOES project some mighty lumens. This is a good, very good thing. Yay Lezyne for that.
Unfortunately, that's really the best thing I can say about it, and things go down hill from there - not in a good, wind in your face kind of way.
I have two gripes, neither of them huge, but in my view, significant. First off, I'm really not getting the battery staying power Lezyne claims on their site. Close, but maybe, 10% short of claims - and that's right out of the box, brand new (yeah, AFTER a full initial charge as instructed). Secondly, I'm not loving their attachment bracket, which, while functional, falls short. It's nothing more than a rubber strap that's not particularly easy to install as snug as you'd like, and I fear it won't last nearly as long as the much better brackets I'm used to from Cateye.
So yeah, it's a good light. Not great.
