Being an avid waterfowl guy I am always using headlamps as well for my big game. I always had 2 or 3 head lamps in my pack or blind bag at a time cause battery's don't last or never got charged or there just not bright enough. I have been running the Black Diamond head lamps now and they actually work!!!! I just like how bright the lumens are and how long the battery's last on them. I am in the field or over a pond setting up 60-80 dozen full body decoys and sure takes awhile and I have to have a lamp that will last me 3 to 4 hrs non stop and be bright. Just want to know which head lamps have you guys found that last and have a DAMN bright light?
