UV light for nighttime blood tracking?

[11boo]

Is this a thing? Would it make tiny blood drops “glow”?

Not unless you are also going to walk through the woods with a backpack sprayer full of Luminol.

Good input, didn’t know if it would show blood or not.

My take;
A good CRI headlamp is pretty darn good

The old Coleman gas lanterns are great if you can find one

BTW, i did a headlamp thread here a couple years back comparing these with photos on how blood shows up at night, high CRI makes a big difference, ( light in the 3,000 kelvin range)

This looks like a good one by you. And I am also a fan of the lights using 18650 and CR123. mine throw a very white bright light, probably as good as anything.

Got this for blood tracking at night. VERY pleased with the brightness and color temp.

Color rendering index...

The different light spectrums [Kelvin index] have different color rendering ability.Some lights can be a very bright white light but suck at CRI. I give examples in the thread linked in 11Boo's post above.

It matters to us as hunters.

For example, the super while light from the newer car headlights is very high 5,000-6,000 kelvin. It is best for distinguishing shapes and clarity...but it washes out colors such as red blood.

2500-3500 kelvin is more like what you get from a halogen bulb; colors are more accurate even vibrant. Thats what you want in a headlamp, IMO.

Hope that helps.

Beautiful, excellent explanation.

Gawd do I HATE newer HID headlights! They should be outlawed from being allowed to be installed in the regular headlamp installation areas. They are far too blinding to oncoming drivers. When I'm coming down outta the mtns I gotta leave my dang sun-visor in the cab at it's lowest hanging down osition so I can lift my head up enough to pull my eyeballs up enough to where they don't get blasted by those damn lights! Especially on like a SuperDuty truck, their headlamps are quite high up so right in your freaking eyeballs!

I'm not at all averse to cars having them.. but Phuq man!!!.. get them sh*ts outta people's line-of-sight for goodness sake! Mount em at top of windshield or roof, but angled down sufficiently that you're not blasting peoples eyes at night on twisty mtn roads blinding them.

BTW Bright white vs Warm White is always an "issue" in our house because you know how the women folk for some reason seem to despise the Bright White type of light bulbs.

As an additional comment, I had one of those high kelvin white light spot beam headlamps that I used to backpack in at night on a hunt and I swear it made me nauseous.

That nausea, I'll bet that was just from dehydration. I had that one time while packing out. That and my upper abs just under my rib cage kept twinging like it wanted to cramp on me.

try putting some scotch tape over the lens. or look for a floody headlamp so it doesnt have a hotspot bouncing all over. a nice even floody light will feel much more natural and you won't notice a light bouncing and moving all over.

I like the zebralights so I use an h53fc on low and just hold it waist high for walking in/out to my spots, and use the h604fc for night blood tracking when I want more light.

Simple fi

They do make blue or violet blood track lights.. we used them back when i lived in south tx and la. not much use now, or even then.. we'd just wait until daylight. Or use a dog.
