Why are LEDS used instead of incandescent lights?
Light emitting diodes–LED’s–are state of the art solid state devices that convert small amounts of 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 patterns of brainwave activity. They also create very pure colors–again an important factor in the alteration of consciousness and brainwave activity.
