Flashlight Tests, under real use.

Does that mean a pruple light would work best...

UV maybe :whistle:

UV would be pretty much useless unless you sprayed the area with luminol beforehand. Fresh blood won't fluoresce under UV on its own, and monochromatic violet wouldn't be any more helpful than monochromatic blue.

The Gerber Carnivore uses a mixture of some low power red and blue LEDs to provide contrast. I think I'd prefer a strong incandescent just for the output, though. I can't imagine the Carnivore has a lot of effective range for blood tracking.

I was joking :thumbsup:

Well, this morning the alarm went off again.

My wife "looked" with the NVD before she woke me up...

She saw a BIG bobcat... came and got me..

I spent over an hour "on the scope" but I think my Llamas ran the bobcat off, so it was... No Joy.

Storms are moving in tonight, but the motion detectors are in place...

Rifle is loaded and flashlights are ready.

I wonder if that really works or it is just a gimic.

Everybody says that blue LED's are good for blood, but this is the third time I have tried it,and even after finding the blood with the SF M6, and THEN shining the Blue LED on it, I could not say that I recognized it as blood.

In my limited experience red (or specifically blood) doesn't reflect light under a blue ALS instead it absorbs light giving it a significantly darker appearance (see pictures below), someone earlier posted about specialized "blood tracker" LED lights using a red/blue combination, well I found a small portable spotlight that makes red colured objects appear to blink as the light pulses red LED bursts whilst permanently lighting the area with white LED goodness, it's called the Xenopus Electronix Blood Tracking light :thumbsup:

The problem seem to be that a bunch of stuff looks the same under these "specalized" lights.

But under the SF M6 [I have used it several times before] red blood looks RED.

That's what I'm talking about!!!

Anyone besides me notice that the "blue" filter that comes with the military issued Fulton angle-head is actually a dark purple, as opposed to the "Bright Blue" that comes on most commercial "Blood Tracking Lights"? I'm nearly 99% positive the military would have studied this in great depth to ensure it worked. We're cooking ribs tomorrow, so I'll see if I can try it out with that, and compare the Fulton blue lens to a commercial blue "blood tracking" LED and let you know what I find out. I'm guessing the blood will be more readily visible with the fulton lens though...especially on darker military/police clothes. (i.e. so you can tell where you buddy bleeding, since blood doesn't show up to well against black))

The "purple" military Fulton filter mimics the effect of a blue/red ALS combination (hence it's colour I presume), the light escaping from the 2 cell incan' via said filter isn't substantial apologies for "dim view" :D
