For daily walk in the woods in the dark winter months the LED Lenser is well suited. If you have used brand new batteries, the LED Lenser lights up the whole forest. Unfortunately oncoming people get blinded, so you better do it, the Always keep light cone ground gen.
But the pleasure does not last very long. After about 2 hours usage it shows clearly how the batteries subside.
Sooner or later the strong LED Lenser lights up no more or less than any conventional flashlight.
