LED Fluence/ Density

It is hard to really know what fluence is when each manfucture told me their fluence is the highest. Lightwave has 2800+ diodes on their 4 panel (but not all of them are the same wavelength. They are split up between reds and infrareds but that doesn't mean it is not delivering a lower joules per minute to the same surface area of just say a POLY LED that has 1800+ diodes of all the same red or blue or infrared. So if someone wants a dual wavelength the Lightwave LED 4 panel has more fluence. There are more LEDS in their 4 panel than POLY LED has in their 5 panel.

If comparing an 80mw POLY diode and a 120mw Lightwave diode but POLY has nearly twice the amount of diodes (nearly twice the fluence as Lightwave), the question is, is having half as many red SBT diodes just as good at twice as many POLY diodes. The joules of energy can be almost identical. Then the question of which LEDs are being reflected back into the LED and which LEDS the energy is being absorbed into the blood. Having LEDS that are too powerful can be a negative thing. With far infrared, the heat is the byproduct. It is the infrared rays that are what the body absorb. There are some really cheap infrared diodes out there that feel totally different than a SBT diode.

Note: some LED companies say their diode is 120mw/cm2 but don't mention that when they are pulsed that it is only delivering 60mw, not 120. They say 120mw when the machine is powered on its duty cycle. That is not an accurate measurement of the LEDs fluence.

Note: There is a very popular LED panel out there that has it's power level ratings so misleading (I will not say their name because if people do their research and know how to compare they will easily see through the misleading information. So when they say they have 30mw/cm2 laser and IT IS FLICKERING ON AND OFF, THIS 50% DUTY CYCLE BRINGS IT DOWN TO 15MW/CM2. 

So, when a LED panel has 10mw/cm2 and the manufacture claims 40 watts, then it can have a 80% duty cycle. On 20% of the time, off 80% of the time. When they flash on so fast it is hard to detect this unless using a tool to measure it.

Note: A LED panel can have tons of diodes giving it a high fluence but if the power density is low, it can still have a high fluence but the penetration level will not go as far in the body. Power density = mw/cm2. A A non pulsed LED will have a sustained energy and a session will take half the time than that same LED if it was continuously on the entire time.

This mask has few diodes compared to some facial LED masks that have many more diodes.
The 2 pictures above are POLY LED panels. This is a single wavelength LED panel that has 80mw/cm2 of constant power. Lightwave has 120mw/cm2 of power density even though it has less diodes. See my diode type page. I compare SBT diodes to other diodes.
