What is a Strobe Light? Is it dangerous? What happens to the eye when it gets “strobed”?
Today flashlights are not just a tool for simple illumination – let us shed a little “light” on an effective defense device.
Our strobe technology can save your life in the right situation. The “Strobe” is a sequence of flashes of light in a certain interval which creates confusion and disorientation. Strobes can be used against offenders, suspects and other opponents. With the rapid succession of light / dark phases it is extremely difficult to focus or recognize the defense or attack movement, or even still, target for a possible attack with firearms or any other weapons.
What does “strobe light” do? Is it dangerous? What happens in the eye when “strobed”?
A strobe light is not the same light as an arc or a welder’s flash. Corneal flash burns are a painful ocular condition. It is also referred to as an arc flash (or arc blast). The event is a type of electronic explosion that results from a low impedance connection to the ground or another voltage phase in an electrical system. A typical commercial strobe light has a flash energy in the region of 10 to 150 joules and has a discharge time shorter than a few milliseconds, often resulting in a flash power of several kilowatts. Larger strobe lights can be used in “continuous” mode, thereby producing extremely intense illumination. This type is much more dangerous than the patent strobe technology of Centurio Design® and was named by military and law enforcement customers “Lightning Less-Lethal Weapons® (LLLW®)” and today a brand of Centurio Design®.
LLLW® Strobe light can cause epileptic seizures when used on photosensitive people?
Most LLLW® flashlights that are freely available, use oscillators (oscillatory system), Centurion Design® limited to about 3-5 flashes per second in their internal oscillators, whereas externally- triggered strobe lights will often flash as frequently as possible. At a frequency of 10 Hz, 65% of affected people are still at risk. The British Health and Safety Executive recommends that the flash-rate for strobe lights not exceed 5 flashes per second, a level at which only 5% of photosensitive epileptics are at risk. It is also recommended that no strobing effect continue for more than 30 seconds due to the potential for discomfort and disorientation.
It can lead to vomiting when illuminated by a LLLW® flashlight / device?
Can LLLW® flashlights / devices with the so-called strobe lights make someone vomit and seizure? There are a lot of debates about these devices and what effects they have. This is because the Military tests have mainly considered the impact on the environment. Meanwhile, there are some rumors and myths that we can really be answered simply. “It makes you vomit,” for example, an American news channel claimed that Strobelights bring the “target” to feel nauseous and disoriented finally causing someone to pass out. Dizziness and nausea are desired properties of the inventors, but nausea is not the same as passing out. “If he close his eyes, the LLLW® flashlights / devices are ineffective”. This statement has most of the professionals amused. If the attacker closes his eyes he can not run away, fight back or use a weapon and resist, so no one can say that any LLLW® flashlights / devices are ineffective. You take the action out of th, and that is exactly what they want to achieve with the LLLW® strobe technology. Many law enforcement officers felt that “If they close their eyes then we have them”.
Physiology of the Eye
Let us review a few basic parts of the eye that are important to understand, what a strobe is, and what happens when the eyes get “strobed”. The eye has the ability to adjust itself very quickly to a steady light. Therefore, the advantage to blind the attacking person gets lost. It becomes harder for the eye to fix on a target behind the light or to determine the distance to the source. The light can thus be used as a protective “shield”.
