HALAR Optical Disruption Mode

• Red Dazzle (290 lm)

• Green Dazzle (380 lm)

HALAR uses 100% eye-safe LED technology and will not cause any eye-damage. The eye will blink as a reflex response to bright visible light.

1. The eye is most sensitive to Green light. Under daylight conditions, the average normal-sighted human eye is most sensitive at a wavelength of 555 nm, resulting in the fact that green light at this wavelength produces the impression of the highest “brightness” compared to light at other wavelengths. AT nighttime, the eye is most sensitive to 507 nm (greenish-blue).

2. Exposing the eye to different colors, especially red and green, interferes with depth perception. This is the principle behind 3D glasses at movie theaters, which put red in front of one eye and blue in front of the other to get a 3D effect.

3. Flashing colors interfere with the brain’s perception of objects. Sometimes called the “Kaleidoscope effect,” they slow down a person’s reaction time.

4. The frequency of a flashing light can significantly increase the distraction and disorientation effects. A flashing light at the right frequency—neither too fast nor too slow—can be more disruptive than a steady light. For instance, flashing white light is more effective at causing disorientation than a steady light, and flashing different colored lights is even more distracting.
