OTOH IIRC someone (you?) in this thread have said that they can tell apart 660nm and 730nm by color.

it was 620 and 660

further up this page I also posted 660 and 730, but the difference is not as obvious in a photo. They still look different side by side (the 660 is more orange than the 730). Plus 730 is like 100x less visible (less bright).

However, even if we cant see it, 730, 810, 900nm all have therapeutic value,
so do 620 and 660nm, and those are easy to see.

so for light therapy, being color blind is not an obstacle

AFAIK we don’t know whether therapeutic value (if there is any beyond placebo) is affected by color blindness. We would need a study for that.

the mechanism of charging mitochondria is not dependent on being able to see the light

and the mechanism of using a red light to relieve arthritis and migraine pain, has nothing to do with being able to see the light. It works even with eyes closed Smile

Have yall been seeing TV ads for the laser hair-growth caps—one site indicates they are using red @ ~650nm.

don’t know if these are just red leds or actually laser diodes, but they aren’t budget items.
capillus website: “Capillus laser therapy devices use only medical grade laser diodes as a light source. “

Now i used to think that i was cool,
drivin' around on fossil fuel,
until i saw what i was doin',
was drivin' down the road to ruin. --JT

Hi guys,

Would this red light be sufficient for the red light eye therapy?

Welcome to the forum Edel21

in my opinion, no, because it seems to use cool white LEDs with a red lens.

Not an actual pure Red spectrum LED.

Instead, I suggest you buy a Sofirn C01R
it has a 660nm Red LED, and the driver has 3 modes.

imo the second mode is sufficiently bright for eye therapy

From reading through the forum Jon, I can see you’ve been using this torch yourself. Do you still practice the red light therapy? Do you hold it at 10 or 28 inches away from the eyes? Do you keep your eyes closed throughout? And is it 3 minutes for each eye?

yes I still use red light to wake up my eyes in the morning

I do keep my eyes closed, and I hold the light about 12 inches away. I move it up and down and left and right, because my reading is that movement helps jump start the nerve signaling, in addition to the red light charging the mitochondria

I dont do 3 minutes, I usually stop in less than 1 minute, but no harm in going a bit longer

as an alternative, you can do the same with morning sunlight. At around 10am the intensity is similar to the red light in the study. You will find this is actually quite noticeable through closed eyelids, and the red light I use, at the distance I use it, is actually less intense than morning sun.

I point that out so you have a reference to gauge how close you can hold the red light, without exceeding the intensity of morning sunlight.

I also use red light on painful spots, sore joints, sore muscles, even painful pimples.. The red light seems to stop pain, for an hour or two. I notice pimples dry out and heal faster, overnight, instead of a few days.

My daughter who gets migraines, solved the problem shining a red light in her nostrils, for about 30 seconds each. An hour later she reported no Migraine, and the next day it did not return. There are a lot of nerve endings to the brain, at the back of the nose…

I also use red light for sore neck and headache, applied to the painful area.

Brilliant. Thank you so much for your comprehensive reply. I really appreciate your time. I will order the Sofirn C01R and use for the same purpose.

the 660nm Red light is called
Sofirn C01R (google that for shopping links)

The C01R only comes in a Red body color

it is quite nice, has 3 useful modes

dont get confused by different colors, and different models such as C01 and C01S.. for 660nm Red the model you want is C01R

Hi
I am building a quad S11 mainly for spotting wildlife just not sure on the led I should use. Is the higher the nm number the better?

Cutter’s has three options that I can see.
1. XP-E2 Cree Far Red 730nm “XPEBFR-L1-0000-00B01” here
2. XP-E2 Cree Far Red 730nm “XPEBFR-L1-0000-00901” here
3. XPG-3 Cree Deep Red 660nm “XPGDPR-L1-0000-00G01” here

MTN has this driver FET + 7135 Driver – 22mm – MTN-22DDm here

thanks for any help

no, 730nm is very dim, not recommended

620nm is much brighter, I recommend that

I was thinking about the nocturnal animals eyes thinking red would be better for them?
I do have a M21B with an osram KP CSLPM1.F1 green light coming.
I will try them both out.

thx

> I was thinking about the nocturnal animals eyes thinking red would be better for them?

if you google red vs green hunting lights, you will learn green is better for seeing animals.

red is better for humans who do astronomy

deer, coyote, boars, dont have good red nor green vision, but green is better for humans to see farther, and to see the fur on the animal

I do not feel comfortable using red, there is something weird about it, for my eyes. With green I feel very comfortable. I would not use red for spotting game, I would only use red if I was doing astronomy.

Apologies for dragging up an old thread, but just spent a few hours going through all 10 pages only to find the Sofirn C01R and C01 are both sold out/out of stock. Is there another recommendation for this application?

you can buy a ready made red light on kaidomain
note that is a dropin, you have the option to buy the host and battery at that link also..

also search amazon for “red light therapy

other options include building your own red light, or hiring someone like skylumen to do it for you

Hi Guys,

Just saw news on red light therapy today at medical news. No real details on exactly what would supply the therapy beyond the implication that fat cat pharma will develop something that will no doubt cost a fortune. I checked amazon etc and there are literally thousands scam listing making false claims. There is serious cause for concern when ignorance is bliss so it was great finding this sight.

This page has a great insight into potential issues to beware of https://medium.com/swlh/the-dangers-of-infrared-light-ir-in-red-light-th...
he also has a book “Living Younger Longer with Red Light Therapy” which might be worth reading. He makes sense in stating the IR frequency is dangerous within red lights but we can use a #5 sunglass to filter just the IR.

The Dangers of Infrared Light (IR) in Red Light Therapy (RLT)
Users of RLT don’t want to develop cataracts in 20 years from IR exposure.
John Iovine

I wont post the page here but its worth a look regards RLT and I would be interested to see opinions anyone might have? RLT seems like a great idea.
If you google “deep red light, with a wavelength of 670 nanometers” it will show the medical news and other articles from the science community.

Just closing eyes should filter out IR, shouldn’t it?

BTW, the 670 nm C01 is sold out at sofirnlight.com, but still available at AE. It’s useable with the above mentioned technique, eye lids will spread the narrow beam.

from Wikedpedia,
In the United States, cataracts occur in 68% of those over the age of 80 years.

Radiation:
Cataracts can arise as an effect of exposure to various types of radiation.
X-rays, one form of ionizing radiation;
Ultraviolet light, specifically UVB;
Microwaves, a type of non-ionizing radiation;

Mr. Lovine’s article is concerned about the 840nm region (microwave) causing damage and thermal cataracts (basically cooking the lens).

i can’t remember who it was earlier in this thread, but one of the forum members suggested closing the eyelids would still provide RLT benefits.

Now i used to think that i was cool,
drivin' around on fossil fuel,
until i saw what i was doin',
was drivin' down the road to ruin. --JT
