Flashlight with blue light

Blue light is very mild. This ensures that your natural night vision is not affected. If you want to read a map at night, blue light is highly suitable. More details and colour differences are visible when you use blue light than when you use red light, for example. Blue light also illuminates traces like blood. This makes this light colour very suitable for investigators, hunters and search & rescue teams. You have torches with a blue LED but you can also choose a filter.
