One constant feature with UFOs, or spaceships, is light. They often first appear as light spheres, they emit light in different colors, they send out light beams. When we speak about light, this is not light as we are familiar with. It is not light sent out from a light bulb, nor is it laser light. It is produced by a different technology. It probably is a very high pulsated frequency of an electro-magnetic field or beam.

A UFO can light up an entire valley at night, and make it as bright as daylight. If this would be ordinary light, such as we produce it, it would require an immense amount of power, and we don't have any devices that would be able to do this.

When a light sphere is close to the ground, even at tree top level, it can light up the place underneath to such a degree that one can see every detail of his environment.

In most cases people are focused primarily on the light sphere, and only in a few rare cases do witnesses notice that the light is emitted from every point in space. This means that there are no shadows. Also, the intensity of the light is the same everywhere within the sphere of radiation. This is strongly suggestive that a field is created that makes all the molecules of the air vibrate at a high frequency. The molecules first absorb the energy of the field (electrons go to a higher orbit), then emits the absorbed energy in the form of light (electrons fall back to their previous orbit). As every air molecule does this, there will be no shadows.

People who have been exposed to UFO light, in close proximity or by being hit by a light beam, have come down with various ailments, from nausea, dizziness to rashes and burns. In some cases these ailments can last for days or weeks, and permanent injuries also has happened. When a person is hit by a light beam, he can feel a tingling sensation, pain, a crippling effect, the inability to move, or become unconscious. It probably depends on how the beam is calibrated. Brazil had numerous cases in which people were actively hunted by UFOs and attacked with light beams resulting in severe injuries, burns, and even deaths.

On a few occasions, people have pointed a flash light to UFO, which immediately send out a light beam to the person, hurting him in one way or another. The aliens do not like a light to be pointed at them. Maybe the light from a flashlight or laser pointer interferes with the high energy physics of their craft, and thus they see it as an attack.

Aliens have a device that shoots out a beam that can have the same consequences as mentions above. It sometimes leaves lasting marks on the skin of the person.

The light of a UFO can penetrate the roof of a house. Actually the light does not penetrate anything, because it is not coming from above as ordinary light would do. The energy field or beam the aliens send out is present outside and inside a house within the area defined by the aliens. The light is the result of the excited air molecules as explained earlier. The light thus present inside a house can also be of extreme brightness. I know of a case where only one room of the house was brightly lit, but the next room was totally dark (it was night) despite the door between the two rooms was open.

In contrast to the entire space inside a house lit up, sometimes, a light beam is seen inside searching around like a search light. It apparently seems to penetrate the ceiling or roof, but is actually a well-fined vertical (cylindrical) area that makes the air molecules emit light.

A UFO can emit a beam towards the ground, and then an alien(s) is seen floating down on this beam, or going back up. It is also well-known that such a beam can levitate a person, and pull him up towards and inside the craft, sometimes with the entire car he is sitting in! Cows have been seen being pulled up this way (in relation to animal mutilations).

These light beams can have different properties. In a unique case, one night in March, 1981, two hunters near the small Amazon town of Monte Alegre said a UFO came down and shined a beam of light at them. One man was "imprisoned" inside the cone of light. He tried to break out but it was as if the outer limits of the cone of light were an impenetrable wall. This continued until the other hunter fired two rifle shots at the UFO, at which time the UFO turned its light off and went away.

The light beam is not always cylindrical, it can have the shape of a cone. In one case, halfway to the ground, the cone of light just stopped in mid-air, cut off flat. Again, a sign that the emanated EM field can be strictly controlled in shape and form.

The beam of light can also be straight and narrow but halfway to the ground the beam can then become conical.

UFO light can leave behind a luminescence. Light beams have been seen going over the surface of water, leaving behind a trail of luminescence on the surface for several hundred yards, gradually fading out. A light luminescence has also been seen of the soil where UFOs have landed, slowly fading out over many days.

UFO light is also seen as bright flashes when it suddenly appears into our dimension, or disappears.

If we want to understand what UFO light is about, we should look to the discoveries of Nikola Tesla. For more than a century, we have been using electromagnetic waves based on the Hertzian model, from radio waves all the way to gamma rays. Tesla discovered a new kind of waves based on electric pulses of rapid discharges. This produced a variety of phenomena that we can also find with UFO light or with just the mere presence of a UFO its particular EM field.

Here is an excerpt from the book Secrets of Cold War Technology by Garry Vassilatos (1996), who devoted an entire chapter to this most interesting aspect of tesla's work. If you want to know more about this kind of these non-Hertzian waves, read the book.

I am not saying that UFO technology utilized exactly these kind of waves, but it seems to be similar. I have put the phenomena we also find with UFO light or UFO emanate fields in bold.

"This was a new electrical force. Tesla realized more than ever that he was in unknown territory. The fact that these radiant forces travelled as light-like rays distinguished them from the electromagnetic waves of Maxwell. The waves were weak, but these rays were strong. Uncommonly strong. Directional effects could obtained by shaping the wire lines which radiated the shocking waves. The condition which best radiated evenly in all directions required that each line be semi-circular, the entire apparatus being circularly disposed. How far did this field extend, and what was the effect of distance on the intensity of the radiant field? Tesla found it impossible to measure a diminution in radiant force at several hundred yards. In comparison, he recalled that Hertz found it relatively easy to measure notable inverse square diminutions within the confines of his laboratory in Bonn. Tesla suspected that these effects were coherent, not subject to inverse laws other than those due to ray divergence. If he wished to broadcast power to a neighborhood, it would be critical that all radiant energy be focused in receivable directions. Also, Tesla wished to determine the effect of gradually decreased impulse durations required greatest skill and precaution. Tesla knew that he would be exposing himself to mortal danger. Controlling the rapidity of current blowout in the magnetic DC are, Tesla released a new spectrum of light-like energies throughout his large gallery space. These energetic species were like no other which the world has since seen. Tesla found that impulse duration alone defined the effect of each succinct spectrum. These effects were completely distinctive, endowed with strange additional qualities never purely experienced in Nature. Moreover, Tesla observed distinct color changes in the discharge space when each impulse range had been reached or crossed. Never before seen discharge colorations did not remain a mystery for long. Trains of impulses, each exceeding 0.1 millisecond duration, produced pain and mechanical pressures. In this radiant field, objects visibly vibrated and even moved as the force field drove them along. Thin wires, exposed to sudden bursts of the radiant field, exploded into vapor. Pain and physical movements ceased when impulses of 100 microseconds or less were produced. These latter features suggested weapon systems of frightful potentials. With impulses of 1.0 microsecond duration, strong physiological heat was sensed. Further decreases in impulse brought spontaneous illuminations capable of filling rooms and vacuum globes with white light. At these impulse frequencies, Tesla was able to stimulate the appearance of effects which are normally admixed among the electromagnetic energies inherent in sunlight. Shorter impulses produced cool room penetrating breezes, with an accompanying uplift in mood and awareness. There were no limits in this progression toward impulses of diminished duration. None of these impulse energies could be duplicated through the use of high frequency harmonic alternations, those which Sir Oliver Lodge popularized, and which later was embodied in Marconi Wave Radio. Few could reproduce these effects because so few understood the absolute necessity of observing those parameters set by Tesla. These facts have been elucidated by Eric Dollard, who also successfully obtained the strange and distinct effects claimed by Tesla.
