How does STUN PHASER work?


STUN PHASER is an LED based deterrent device designed to induce aversion responses such as blinking, blocking, and other actions to remove oneself from the light source.  Its high intensity light bleaches photoreceptors in the retina, causing black spots in the field of vision.  In addition, red and blue lights pulse at two overlapping frequencies, 12-15 Hz and 50-60 Hz, causing over stimulation in the sensory processing system.  Human brain has a limited capacity by which it can receive and process visual information.  Overloading the sensory processing system causes disorientation and induces automatic aversion responses.  The effect of the discomfort fades a few minutes after removal from the light source. 


Does STUN PHASER work?

STUN PHASER is an EN62471 Risk Group 2 certified light source.

What is EN62471?

EN62471 is the European New Standard for all lights and lighting systems including LED. Classification of products are based on the following:
1) UV damage to skin and eyes
2) Near UV damage to eyes (315nm-400nm)
3) Blu-ray damage to the retina
4) Blu-ray damage to the retina (small light source)
5) Thermal hazard to the Retinal
6) Thermal hazard to the Retinal (for weak visual stimuli) (780nm-1400nm)
7) Infrared radiation hazards to the eyes (780nm-3000nm)
8) Thermal hazards to skin (380nm-3000nm)

What does EN62471 Risk Group 2 mean?

A Risk Group 2 category light source triggers an aversion response within 0.25s.  Typical aversion responses include blinking, head movement, constriction of the pupil and continuous eye movement to limit the amount of light reaching the retina.  For STUN PHASER, only the physical movement away from the light source can alleviate the discomfort caused by the STUN mode.

What is photosensitive epilepsy?

Photosensitive epilepsy is a type of epilepsy where almost all seizures are triggered by flashing or flickering lights.  Roughly 3% of the total 2 million plus Americans who experience epilepsy fall in this category.  It is most common between the ages of 7 and 19 and affects more girls than boys.  Most people with photosensitive epilepsy are sensitive to 16-25 Hz (frequency of flashes/flickers in a second).

Can the STUN PHASER trigger photosensitive epilepsy?

STUN PHASER’s overlapping pulse frequencies are 12-15 Hz and 50-60 Hz, placing it in the triggering range for photosensitive epilepsy.  It is important to remember that STUN PHASER is intended to trigger aversion responses.  Behaviors that remove a person from the stimuli will reduce the risk of over stimulation.  Please consult medical professionals on how to manage a possible epileptic situation.
