Hunting Hogs and varmints with RED and GREEN LED FEEDER LIGHTS and SPOT LIGHTS.
This is a widely discussed, widely debated and widely misunderstood topic.
_______________________________________________
UPDATE 02-04-18

Research now clearly supports the fact that hogs, deer, (Ungulates) coyotes, bobcat (Varmints) and most native 4 lgged species are DICHROMATIC RED/GREEN Clor Blind.
DICHROMATICISM, in simple terms, deals with "SATURATION".
The eye structure (without all the technical lingo) suggests they are colorblind beginning at 530 to 540 NM, with an exception to the levels of saturation.
This explains how they pick up on LASERS (laser dots) due to the high saturation level.

The following Wavelength chart indicates that hogs can in fact pick up on GREEN well before they can pick up on any levels of red, yellow or orange.

Chart along with explanations of Dichromaticism would indicate that animals are capable of picking up powerful GREEN Hunting Lights. Especially if they have hard edges.
Which does explain why many of the GREEN HUNTING LIGHTS scare animals.

I would encourage readers to go here and look at the real world photos and videos using RED GREEN HUNTING LIGHTS

I will attempt to explain what hogs, deer, and varmints can see and can not see in a way we can relate to it and understand it.

:arrow: Hogs, deer, varmints as well as most other 4 legged critters are fully RED GREEN color blind.
:arrow: Humans are fully INFRA-RED color blind.
Using this similarity I will explain what can be seen and can't be seen using red and green LEDs so its understandable.

:arrow: How can we relate to this and understand it :?:
It's easy. Most everybody has an INFRA-RED trail camera or has access to one. Many modern cameras and camcorders also use infra-red LEDs.
Humans are INFRA-RED color blind so we can use those devices to understand what RED GREEN color blind anaimls can or can not see.
Are you catching on now?
Take your camera into a room that is totally dark. With the infra_red mode on take a picture - in the case of a camcorder just turn it on, the infra-red leds will be ON when the device is recording. What do you see?
:arrow: you don't see nothing but DARK. You don't see shadows, you don't see any illumination because we are color-blind to infra-red color spectrum. NOW, turn the camera and look into it the lens (take a picture so the LEDs will come on) Around or near the lens you will see the infra-red LEDs glowing :thumbup: :o :clap:
That's a real simple, well that's what a fully red green colorblind hog, deer, varmint will see using RED High power LEDs in the dark. That's not complicated. :shifty:

Here's a more in depth down to earth explanation.

The cameras use LASER DIODES that project the INFRA-RED spectrum of light. So, when the cameras turn “ON” to take a picture we can see the LED Emitters glowing but we are color-blind to the INFRA-RED Spectrum they project. So, if it's pitch dark, there are no other spectrums of light and an INFRA-RED spectrum is projected, we would remain in the dark unable to see.
We can see the LEDs glow but we can ”NOT” see the illumination (refraction) they are projecting outward. Not even if it's pitch dark. YET, the camera itself can see it and use that light (rerfraction/illumination) to take a photograph.

Now, we're going to switch roles from above.
We humans will become the camera, the camera will become a red flashlight, green flashlight, or TEXASBOARS FEEDERLIGHT. We (as the camera did) can see the illumination projected by the LASER DIODES.
However:
The hogs, who will take over our role as having used the camera, can NOT see the projected spectrums of RED and GREEN illumination. The same as we humans, INFRA-RED color blind could not see the projected illumination from an infra-red LEDs.

We need to remember, the hogs can see the LEDs glowing, just as we can see the infra-red LEDs glowing. That's why I have stated in the past and on these forums, that LEDs absolutely can scare animals! That's exactly why, the competition falls short. They use crappy cheap low-powered LASER LEDs that will only provide sparing amounts of illumination. Therefore they have to be installed only a few yards from the bait. Right up in the animals face and in their safety zone. It clearly scares some of the smarter bigger animals.
TEXASBOARS FEDERLIGHTS and hunting lights are NOT set up at the feeder or bait, TEXASBOARS lights are in the “STAND” with you! 50 yards, 75 yards, 150 yards away from the feeder. You simply turn the light ON and adjust it from the comfort of your stand. Bring it back home when your through hunting. There is no need to "leave the light running so the animals will get used to it". They can't see it. Therefore there is no need for solar panels, no need for dusk to dawn switches and by all means you absolutely would not ever use "motion sensors" for the reason of the animals getting used to the light. Unless, the light is so poor and weak it has to be installed on or just yards from the feeder. That CAN and does scare some animals. They will not get used to it, because they will never return.

Next we can address another confusing and widely misunderstood topic.
SO, why can a dog, cat, squirrel, raccoon and other animals that are red green color blind see a laser pointer?
EASY!
Animals are “NOT” color blind to the LASER SPECTRUM. Laser spectrum is completely different than the common red spectrum’s.
A laser pointer or laser pen is a small hand held device with a power source (usually a battery) and a laser diode emitting a coherent (tightly focussed) beam of visible light, intended to be used to highlight something of interest.
In other words, without a bunch boring scientific crap, they “project a coherent laser spectrum”.
The high power LEDs we as hunters would use in the field are also classified as laser diodes. The difference we need to understand is they do not project a coherent laser spectrum, therefore the refraction or “illumination” is a different spectrum than that of the emitter. Only the emitter itself is in the laser spectrum. Just like the INFRA-RED LEDs used in a trail camera.

Thanks for reading.

Abstract Two experiments were carried out in order to clarify the color perception of Japanese wild boarsSus scrofa leucomystax. Two females were trained using an operant conditioning technique to press a switch under a positive stimulus color card in order to receive food as a reward. In Exp. 1, they were tested for discrimination between 3 colors (red, green and blue) and gray. The luminosity of all colors was the same. The wild boars succeeded in discrimination tests between blue and gray, but failed to discriminate red from gray. They also did not discriminate green from gray so clearly as blue from gray. In Exp. 2, the same wild boars were tested to discriminate between 8 kinds of color, which were created by gradating green yellow into red purple except for the 3 colors used in Exp. 1, and gray. They could clearly discriminate blue, purple blue and a part of purple from gray. In these experiments, wild boars were capable of recognizing bluish colors. However, for colors approaching green or yellow, they failed the test by degrees.
-----------------------------------------------------------------

Conclusion
They are fully RED color blind
Partially (by degrees unstated) GREEN and Yellow Color Blind.

You are as adamant about a pig's red-green light color blindness, with justification, as I am adamant about promoting the use of the chemical Permethrin as an Insect Killer, with justification (US Army uses it extensively). I believe you whole heartedly about the R & G lights.

I am about to "pull the trigger" on the Classic 2x6 RPG (nice pun) for a new tower stand ~90 yards away from the kill zone. I will be looking into solar recharge of twin 12V Marine Deep Cycle Batteries, in parallel (same voltage, longer duration), which this 18 watt light system will most likely need for ~5 hours of steady light. Any recommendations?

Excellent sales pitch Sir! Well done and the new on-line catalog is coming along nicely. Two AM to "finish" is a long day...just saying.
