Light Emitting Diodes (LEDs) are another form of Biophoton Light Therapy, that is a relatively recent development of the Laser Industry. LEDs are similar to Laser Diodes inasmuch as they have the SAME Healing Effects, but DIFFER in the way that the Biophoton Light Energy is delivered. A significant DIFFERENCE between LEDs and Laser Diodes is the Power Output. The Peak Power Output of an LED is measured in milliwatts, while a Laser Diode is measured in Watts. However, this difference, when considered alone is misleading, since the MOST Critical Factor, that determines the amount of Biophoton Light Energy delivered is the Duty Cycle of each Diode.

An LED usually has a 50% Duty Cycle. That is, the LED Pulse is "ON" for 0.5 seconds and "OFF" for 0.5 seconds versus the 200/1,000,000,000 (200 billionths) of a second burst from a Laser Diode at 1 Hertz/Pulse per second. Moreover, an LED is "ON" 50% of the time and "OFF" 50% of the time, regardless of what Frequency/Pulses per second Setting is used. On the contrary, the Laser Diode is "ON" for 0.000000000005 of a second and "off" for 0.999999999995 of a second. In short, the LEDs emit MORE than 33% MORE Biophoton Light Energy, than a comparable Laser Diode, because of the substantially LONGER Duty Cycle, eventhough the Peak Power Output is LESS.

In the majority of Laser Diodes on the market today, the Biophoton Light Energy Output varies with the Frequency/Pulses per second Setting, so that the LOWER the Frequency/Pulses per second, the LOWER the Peak Power Output. The Peak Power Output of a Biophoton Tool is CONSTANT, regardless of Frequency/Pulses per second. Even in the case of Laser Diodes, that claim a Peak Power Output of 10 watts, because of the VERY SHORT Duty Cycle, the average Power Output at the HIGHEST Frequencies is in the order of about 10 milliwatts. At the LOWER Frequencies, however, the average Output PLUMMETS into the range of microwatts (1 microwatt = 1000th of 1 watt).

LEDs do NOT deliver ENOUGH Power to DAMAGE the Tissue, but they do deliver ENOUGH Biophoton Light Energy to stimulate a response from the Body to HEAL itself. With a LOW Peak Power Output, but HIGH Duty Cycle, the LEDs provide a MUCH GENTLER delivery of the SAME Healing Wavelengths of Biophoton Light Energy as does the Laser Diode, but at a substantially GREATER Energy Output. For this reason, LEDs do NOT have the SAME risk of ACCIDENTAL Eye Damage, that Laser Diodes have.

Moreover, LEDs do NOT produce Coherent or Collimated Light, but they do generate a Monochromatic (single-wavelength) Light Beam, which a Laser Diode also does. Non-collimation and the wide-angle Diffusion of the LED confers upon it a GREATER ease of application, since the Biophoton Light Emissions are thereby ABLE to penetrate a BROADER Surface Area.
