- Which color is the best to use during nighttime tactical operations, and why? Instructor White does his best to explain.
Used in this instructional are the Walther XT2 (400 lumen) with filters, and a 10 lumen size AAA micro torch. - Sport
I never thought that a full-grown man will explain me things about the army... under a blanket with a light to his face.😅
Thank you so much really needed that info !
I taught night vision goggles helicopter training at the US Army school-house (Ft. Rucker, Alabama) for years... If you want to be sneaky, red light travels the least distance, and is harder to see by the human eye due to the Perkinje shift effect when the eye starts to dark adapt. For home defense, use an intense blue/green flashing light to stun your target.
There's also recent research that indicates that blue light at night can disrupt your sleep cycle - blue light will wake you up. Especially if you're sleeping while people are trying to be sneaky around you with blue lights. It is also proven that blue light is responsible for the damage of photoreceptors, and overexposure can cause blindness.
@@Sara-L keep your hand off it, it also causes blindness!
I read that somewhere, so it must be true 😜🤯 lol
Not true with the red light distance. If you sit a above a city. You can see the red stop lights go on and off, better than you can see a green light. Or blue. Even at ten miles away. Red is a Long wavelength. Green is shorter.
Don't believe me! Sit on a hill above a city or town and see for yourself. (0321)
You can see a cigarette cherry from a thousand yards at night.
@@Sara-L It isn't so much blue light, but any light or disturbance can disrupt the sleep cycle. Which is of course common sense but many people don't realize having their lit up clock or TV on does interrupt their sleep.
I drive tugboats night watch. I don't know anything about combat environments, but from what I see out here, red is extremely visible. Even a fairly dim red light is visible for a mile over the water. Orange is behind it, followed by white, then green. Blue seems to travel the worst, but oddly close blue light ruins my night vision, while red has the least effect.
*Thank you! When I was in The Army during night operations, I always closed one of my Eyes whenever a flashlight was turned on irregardless of what the color was being used! It helped me Tremendously!*
I am interested, please elaborate further. Thank you.
@@Anxiou5Panda the closed eye will remain adjusted to the darkness, the open eye will become adjusted to light
IRREGARDLESS???
In my opinion red is the best for camouflage because it doesn't reflect well from green items like grass, leaves and most likely your uniform. Green on the other hand would make you very visible and in the night every other thing that is not illuminated artificially is either black or dark grey.
I looked up that green lasers can be seen further. So red does help a lot to keep you hidden in the dark.
Thank you, this has been useful in picking which chemlights to use where.
Useful video nice job bro
Very helpful info . Thanks
Everyone forgets yellow-green for cockpits/NGGs
You're wrong. Red is the most stealthy if you want to avoid detection.
Was thinking the same thing, red is not reflected well from green items like uniforms, leaves, grass and it's also at a limit of the human visibility spectrum.
According to lasers, green can go further. I would think red would keep you more hidden do to distance.
what happens if you need to fine IVs what would you use
Thank you for that video
What color is best to avoid detection by mother while sneaking cookies from the kitchen at night?
NVGs
red
Nice dude, Thanx
Is this the real life? Is this just fantasy? Good comparison Instructor!
I wish blue lights were illegal for transit vessels, they really do blind oncoming drivers. Thanx.
Wait it's supposed to take 45 mins to get your proper ngiht vision back? Huh I'm guessing 2 mins is kind strange then?
What color works best with infrared
Infrared doesn't care very much for the color of light necessarily... only the heat from the creation of light. That being said, there is near IR (750 nm to 1300 nm wavelength). The 700 nm range is close to the edge of the color red wavelength. IR also has a medium IR (1300 to 3000 nm wavelength) and far IR (3000 nm to about 1000 microns). Hope that helps. Sorry I did not see your question... YT sometimes does that. :-/
I found out that blur doesn't register the nightvision
In conclusion, outline bodies of water and trace rivers on your map overlay then stick to blue light at night.
Is it true the story of the Vietnam red night vision testing that had people seeing weird things?
Yes, starlight pnv-an night vision was in red, guyscsaw creatures in other dimensions.
@@deanc.5984 But this has nothing to do with normal red light.
I recently purchased a Thermal electro optic…. I can see the true shapes of people and beings walking by…. All I can say is…. They are among us 👽 👹
People say that red “doesn’t travel as far” but, scientifically, blue has a shorter wavelength and doesn’t travel as far, it would penetrate less through any sort of smoke, brush, clothes, glass, dust, etc. sunsets are red for a reason-it’s the red light that gets through.
Does that make it better for mot being detected? Idk.
IR has a longer wavelength than Blue yet Blue definitely travels further. But yes, warmer colour temperatures penetrate Fog, Smoke better. But in normal conditions, Cooler Whites are more brighter. There's a good reason the Sun is very bright on a clear day. The Sun when setting is still dangerous to look at, but is more dimmer.
In short, every Colour has it's purpose.
@@stoopidhaters Blue travels the least far of all the colors. Reed travels the farthest of visible light. And if you don’t believe me, or scientists on the internet, then a red light and a blue light and hold pieces of paper in front of them, keep adding papers until you can’t see the lights anymore. The red light will shine through more papers. It’s the same reason your earlobes glow red and the sunset is red and air traffic lights are red and spotlights all use warmer tones.
@@hunterterrell9930 Yup, that's why we transfer data with longer wavelengths, it can just travel further undisrupted :)
哈哈哈哈哈哈哈哈
Umm, pretty sure Red is less likely to disturb my neighbours. I think you're mistaking the fact that Green Light doesn't scare away animals when you're hunting. Of course Green sits in the middle so you're less likely gonna get detected using Green instead of Blue.
Let's take a look at Christmas Lights. The LEDs are all the same Wattage yet the Blue ones are the most noticeable.
Here's another thing. On foggy nights, the Cooler White Flashlights have a more noticeable beam where as more Warmer tints penetrate through the Fog.
