Treatment times: 
The fastest LED light therapy devices will have have the highest concentration of diodes per cm2. The highest out there right now is 120mw/cm2. The latest diodes are more compact and right at this present time there just can’t fit any more diodes to make it higher than 120. That’s a lot of joules per minute in such a small area. (note: many companies at the show that I talked to I busted saying that theirs goes up to 80mw/cm2 and that is the highest they go. I have a spectrometer and I should have taken it to the show to bust them on the spot. Most of the brands I have tested don’t go higher than 40mw/cm2 which can be checked on the spectrometer.

To have fast sessions and go really deep into the skin, it must have at least 10 joules per cm2. A 120 mw/cm2 compact diode array will have that. 80mw/cm2 is high and usually good enough for most people unless a clinic needs to see more people and needs faster session times and then I would recommend a 120mw LED.

Those buying for home use can get by on 50% of this power and can get the same benefit from a 60mw/cm2 LED. This delivers about 5 joules per minute. The Lightwave react Lt model is the model that I buy the most of that costs under 2000 dollars. It has the SMT diodes also which are not the early generation types. (If a residential user wants the React LT model, I am not allowed to give the practitioners price to the end user. Have any health practitioner buy it for you and you will save off the retail price. This goes for pretty much any LED. 

There is a huge markup on these from all the price sheets I have in my hand and I just mark them up a little to keep my site up and pay my employees. (I have another site called Coldlaserstore.com, ColdLasersReviewed.com, and LipoLasersReviewed.com). Those are my main businesses and the LED is just a side venture I started as I tried a Celluma Pro and I wanted to know what all the hype was about so I bought one. Then I went and bought a few different brands and then I went to the Aesthetics and Spa show in NYC and tried all the different brands and spent 3 days comparing them all and hearing complaints from estheticians that have these and why they are looking for more powerful ones.

The complaint I got most is the sessions were too long and they needed a higher powered LED that could dissolve serums and creams better. Those using it for pain relief typically wanted to have shorter sessions for their clients. With my spectrometer and other tests I did, the Poly brand came in number 2 with the second highest fluence. 

Theirs goes up to 80 mw which is very high and have diodes there were different than Lightwave and Lightstim. Their price per diode and mw is much lower since they were one of the newer commercial LED therapy lights on the market into this niche.

(MANY PEOPLE DONT KNOW THE DIFFERENCE BETWEEN being at a high voltage (-50) and being in a healing state and being in pain and the difference of being in the same pain but being in the degeneration state (lower than -20mv). So when people go to get treated by a LED, the patient should know what state they are in. It is stupid to bring something that is already in the healing state and bring them back to the inflammation state. I can only understand if people are under -20 mv that come in for treatment.

For those who are concerned about treatment times and want to know real world treatment times, not based on the Peak wavelengths measured in a perfect setting with a person with low blood volume that makes the company put a shorter treatment time, I know how tests are done and how joules of energy are measured and reflection rates. Nothing can get past someone who has reviewed LEDs and lasers and also has many laser and LED sites. I have customers that can give their negative feedback that will back up anything I say.
I don’t just makeup stuff to sell a LED. I can back up anything from FDA studies and can prove the product I am selling has accurate specs and is backed up. Make contact if you need my help.
