Thread: Neutral white or cool white better for seeing blood?

  1. #1

    Default Neutral white or cool white better for seeing blood?

    Looking at the Quark series and see they offer a few left in neutral white too.

    Any idea on which would show minor blood spots for tracking after dark?

    I have no real idea, but I was told that hunters are after greenish tints.

    Normally, you should use blue light for seeing blood as I learned and if hunters want greenish tints, we have the cold side of colors. So, the cool white should in theory be best...

    It's been my experience that the neutral whites give far more feedback on reds than the cool whites do. If there's some blood 20 feet away on a patch of brown grass it will pop out, do that with a cool white and you may not even notice.

    Neutral, by far. The warmer the tint, the better. Cool blue LEDs have very poor red output.

    They don't, but if you pair them with red then you can get some decent contrast going on and the red blood will seem to "pop" better.

    It seems you're right. Blood looks black under blue light. Perhaps blue is only good to make the distiction between blood and other liquids?

    I could have thought about that from my time as an amteur photographer, using filters. The whole color thing is quite difficult.

    I only walk through the forest, hoping not to meet any blod on my way. For that purpose, a neutral white light is much better than a cool white, as teh color rendering is better. Best is of course high CRI, but you may say that neutral white renders in general better than cool white. It isn't true however, that a high CRI light must be an extremely warm light. Difficult discussion as well...

    Neutral white would probably be better due to more red output.

    I have not found Blue to be a good blood finder.
    I have a SureFire with the Blue LED.

    Incandescent works best for me.

    My SureFire M6 works best of all. If I am having a hard time following a blood trail I get the M6 out.

    It's said that the old Coleman fired lantern is better than any flashlights for tracking blood outdoors.

    Guess what... My wife was so interested in helping answer this question that she ran down a deer with my truck this morning!! She woke me up @ 6:30 with a phone call giving me the news... Anyway long story short I had the deer and blood in/on my truck and it was still dark. I remembered reading this question yesterday so I grabbed my D10 Q5 and my Quark warmy... Drum roll please... I could see the blood from further away with the warm/neutral tinted Quark... Up close I couldn't tell much difference.

    Oh well I'm off to look at deer jerky recipes, and for a new grill for my truck...

    Blood does look black with a cool tinted Cree.

    They are probably the same in effectiveness, but the cool tint is counter-intuitive to what you would expect to see.

    To be honest, you might want to get an Incandescent light if you want to see blood and use a LED light for everything else.
