Why are blue LEDs used instead of incandescent lights?
Light emitting diodes — LED’s — are state of the art solid-state devices that convert small amounts of safe electrical energy into light. They can be switched on and off much faster than incandescent lights, producing the crisp strobe-like pulses which have been shown to be most effective at inducing the frequency following response needed to guide the user through the brainwave states. The blue LED was picked for its very pure cool color. Our operational research showed that users prefer the blue effect through closed eyes better than any other LED available. It is important to note that a person who is prone to seizures should not use the light portion of the NXTLynk™ system.
