INTERNALIZING LIGHT ENERGY
The nasal channel is saturated with permeable blood capillaries.
Vielight technology delivers optimized light energy to blood that flows through the nasal channel.
Convenient and effective, systemic photobiomodulation has never been easier.

Systemic Photobiomodulation
The nasal cavity is saturated with blood capillaries and five major arteries connect directly to the circulatory system – making it the perfect location for non-invasive systemic photobiomodulation.
Vielight systemic photobiomodulation technology is hypothesized to boost the immune system and increase blood oxygenation levels.
Theoretical benefits include :
Increased energy levels
Enhanced aerobic fitness
Immune System
Up-regulation of cytochrome c oxidase
The mechanism of photobiomodulation is proposed to rest on photon absorption by cytochrome c oxidase (CCO).
Since CCO is an inducible enzyme, a longer-lasting metabolic effect is achieved by photobiomodulation up-regulating CCO concentration, which in turn enhances the capacity for cellular oxygen metabolism.
Release of Nitric Oxide
Photobiomodulation of the blood has been shown to increase nitric oxide (NO) and hemoglobin concentration (Δ[HbO]) as the electromagnetic energy dose accumulates over time.

VIELIGHT 633
The Vielight 633 Red is a compact personal photobiomodulation (PBM) device. Its 633 nm wavelength is ideal for systemic photobiomodulation.
The LED of the Vielight 633 Red releases non-coherent cold LED light that is bright red and visible to the human eye.
Parameters | Values |
---|---|
Wavelength | 633 nm LED |
Power density | 15 mW/cm² |
Effects | Increased oxygenation |


VIELIGHT 655
Similar to the Vielight 633 Red, the Vielight 655 Prime emits a powerful beam within the visible red range in the electromagnetic spectrum.
However, the Vielight 655 Prime utilizes a cold laser beam instead of a LED beam. The efficacy is theoretically similar between the two models.
Parameters | Values |
---|---|
Wavelength | 655 nm Laser |
Power density | 5 mW/cm² |
Effects | Increased oxygenation |
VIELIGHT X-PLUS
The Vielight X-Plus is a versatile and hybrid photobiomodulation device.
The 633nm intranasal diode irradiates the circulatory system via the nasal capillaries.
The 810nm X-Plus module can be placed over the cranium, the vagus nerve, shoulder etc.
