Abstract: A lighting arrangement for treating a user having a neurological disorder and/or for growing plants includes a light emitting device that emits a first light within a first wavelength range of 620 nm to 750 nm at a first intensity, a second light within a second wavelength range of 500 nm to 565 nm, and a second intensity between 30% and 50% of the first intensity, a third light within a third wavelength range of 565 nm to 590 nm and a third intensity between 25% and 40% of the first intensity, and a fourth light within a fourth wavelength range of 435 nm to 500 nm and a fourth intensity equal to or less than 30% of the first intensity.

Abstract: An ocular light therapy arrangement for treating a user having a neurologic disorder includes a light emitting device the emits a light having a flicker rate of less than or equal to about 2 Hz and/or greater than or equal to about 85,000 Hz at a wavelength of within a first range of from about 500 nm to about 565 nm, wherein the light is effective to reduce neurologic disorder symptoms by reducing stimulation of the user's retina and brain cortex.
