Ive got a Lezeyne 1300xxl and it is really good. The light pattern is wide while still projecting up the road. I usually run it on medium and I would guess I get 6-8 hours out of it. On high it can burn through quickly, but I dont ever need that much light.
I also had an L&M Taz 1200. That thing would overheat itself (even on 40F mornings) after 15 minutes on the top 2 settings and drop down to the lowest light which was generally when I entered a wooded path. If it didnt do that I would have stuck with it. I found the light to be much wider, but didnt project as far as the lezeyne.
