I have owned 15 headlamps over the years. I currently own the Princeton Tec Apex. It runs on 4 "AA" and is the most useful and brightest headlamp I have ever seen. We go hiking at night and I bring up the rear of the line and with my headlamp on, no one else needs to use their headlamps. Very bright, long distance beam, waterproof casing and flood LED array option for when that single 3 watt 130 lumen LED is too bright. It sounds perfect for what you want to accomplish! PT Apex headlamp!
