I have zero experience with head lamps and would like to purchase one. My uses would be night time yard work and a SHTF headlamp. I would like to wear it on my bare head and in the winter over a hat. I'd prefer CR 123 batteries. I would like to be able to use the lamp for night time navigation and also have low lumen setting for longer runtime, mabye 10 lumens. You would be surprised how bright 10 lumens is in pitch black night. Also I have seen some models that a horizontally rotating bezel to adjust the direction of the beam.
Any advise?
