Why do we use the red 660 nm lights?

About ten years later at the University of   Chicago, researchers discovered that the average wavelength of cell tissue in the human body ranged between 600 nanometers and 720 nm; 660 is the mid-point. So in essence, the reason a 660 nm works better than any other single frequency is because it is closer to the resonant frequency of cell tissue. The other reason is that 660 nm absorbs better in hemoglobin.

As you move toward the red end of the spectrum, the rate of cellular regeneration increased. For instance, a single frequency in the green range might affect the kidney 40 times better than a normal base-line study, whereas a red would be about 4,000 times faster.

So over the years they migrated to infrared, red and eventually the 660 nanometer wavelength because it was the fastest way to regenerate tissue. So if you have an injury you would normally recover from in ten days, you can actually recover that tissue in two days by treating it with light.

Irradiating mitochondria with red and infrared light causes them to produce cytochromes, which increases their efficiency.


What does the number 660nm mean?
The 660 signifies wavelength, the nm designates nanometers which is measurement of length, so 660nm would mean the distance between the light waves is 660 nanometers. It is also a way to specifically exactly state a color.
660 is deep Red
635 is a more orangish red, most common red color
590nm is yellow
520nm is green
470nm is blue
400nm is violet

What do the different colors do?
Infrared 880:  Stimulates production of nitric oxide in blood which open up the capillaries thus increasing the blood flow, also the most deeply penetrating.
Red 660:   Speeds up healing and increases production of ATP in the cells, which is their energy source.
Yellow 590:  Stimulate collagen production to helps with wrinkles, recently found out the red does it too.
Blue 470:  Works on Bacteria, MRSA, Jaundice and inflammation to some degree.

What is the option boost power and fan, and what does it do?

My LEDs are good for about 15 to 20 minutes at a time and then they get pretty warm, which allows you to use it on 3 to 5 areas in one session. If you have larger areas to cover then getting the fan option is a good idea. You can also add the boost/fan option for a little more output, which is approximately 20% more. The fan is added inside the LED unit and some holes are put on the back to allow the air to circulate. The boost power is an adjustment in the circuit that allows more power to the LEDs which makes them get worm faster, so I add the fan to keep it cool.


What is the power output of my LEDs?

I had my main LEDs tested by a man with a device that measures them directly. Here are the results.
For calculation there are 4 LEDs in a square centimeter, multiply the below figures by for to get the  mw per cm2 rating.

Where are we located?
We are located on the central coast of Sunny California in Pismo Beach.
Where do we ship to?
We ship world wide and include a universal power supply for international orders. We also add a plug adapter so you can plug it in right out of the box and start using it. For domestic orders a standard 120 volt power supply is included, so if you intend to travel overseas with your unit be sure to drop me a line, and tell me to include the universal power supply and plug adapter for the country you are going to. Email lights@theledman.net
  
What does shipping cost?
For USA shipping is 10 dollars for one unit and 15 for two or more units. For International shipping is 15.00, We use Priority Mail  with USPS
How soon will my order ship?
Usually your order will ship in 2 to 3 days depending on workload. Each order you place is individually made, so if there are a lot of orders it will take longer before it is your turn. Sometimes I have to wait for parts if I run out or have to make a special unit for you. So there are times when it make take a week up to two weeks for some orders. Most of the time it ships out the next day or within 2 to 7 days. Priority mail in the USA takes about 2 to 3 days. International usually takes about a week sometimes more depending on the country. If your are worried about your order email me. I am usually on online all day long and will answer as soon as I can. If you don't hear from me within 24 - 48 hours then I probably didn't get your email, or am buried in emails, and so you may try to send it  again, or my reply ended up in your spam folder. Sometimes I can't get through to customers due to spamfilters. lights@theledman.net
