When you rely on just a headlamp then it is important to know how wide the sector is and the dead angle. Remember that the headlamp is directed forward and it may be very difficult to see from behind.
Usually the light will reflect on the water or kayak for example and you will be seen.
Lube the thread
some care with lube so it does not get into the housing. If it mixes with substances it may be a problem.
times you can read about night vision and how the eye adjusts for the night or darker places. If you suddenly should get a light beam in the eye then this will ruin your night vision. There is also a different and important phenomenon and here is what I mean:
Today the flashlight is getting better and better and like we know night vision can also be trained. If we continue to use more and more powerful lights at night then we will not train the night vision but
rely on stronger lights. It is almost like we need stronger and stronger lights. I recommend doing a small test. Try to use an old style bulb MagLite AAA and see if it can function for the things you used to do with it. If you cannot use it then the night
vision is less. When we first got a flashlight with 200 lumens (if we can call it lumens) it was a great thing! Today this can looked upon as a candle flame.
Usually the mental mechanism to be in
the dark is to adjust for night vision and to function in the dark. With an extreme amount of power from a light then the mental attitude will be more to forget about the dark and just rely on the light. This will make it more difficult to adjust again and
more difficult mentally.
Around people a headlamp made for close use can be very helpful .It is smart to use the angle
function on it because this can be used to avoid the beam from hitting others around you.
