I have a Nitecore HC90 headlamp. I see that it has been discontinued. What would be a suitable replacement for it? I typically use it for night horseback riding. It is attached to my Troxel equestrian helmet and lights the trails up pretty well. Having something that runs on a single 18650 is great. I would also consider a headlamp that uses two 18650s or a single 26650. (Are there any that use a single 26650?)
