Nice test Vestureofblood! This is unique test to bust all kind of flashlight blood tracking sellers that are selling real “myth” for costumers believing that red, blue, green light does make difference while their only function is to blind you while tracing for blood trail.
If someone finds/invents flashlight that really works with blood trail it will be big hit in hunting world cause every hunter wants one in a backpack.
Until that light appears I will just stick to cool white zoomie which works the best of everything I seen or tried till now.
P.S. It gotta be zoomie? Why?
Zoomie light without any spill unlike the reflector light has very sharp borders, so there is better contrast between illuminated area and dark area. The enhanced contrast lets you perceive blood trail better and you have preserved night vision.
