Being as avid a hunter and outdoorsman as I am, I use headlamps all the time. Throughout the years I have found that I need to keep 2 types on hand.
1) Cheapo Energizer or such with 4 LEDs for working on things like vehicles.
2) A nice headlamp like my Black Diamond I have. It is something like 160 lumens for white light and also has a red lamp installed as well. The red is useful when trudging through the woods in search for your hunting spot. Not sure why Amazon has it under review.. I have 2 of these and love them.
No matter what type you get or how many you get, these devices are great.
