Hello. I’m interested in building a red light therapy hat. But I’m having trouble finding a source for 670nm and 810nm led strips. I was wondering if anyone who has built a hat using these specific wavelengths could share a link to where they purchased them.
Thank you.
Brain stimulation technology e.g. from the companyVielight (Neuro Duo - Brain PBM) Photobiomodulation device for the brain - I have been using this three times a week in “gamma mode” since November 6th, 2021.
Since the beginning of May 2023 I have also been using the helmet fromSymbyx Biomes.
A friend made my hat for me so I don't have the exact link, but they came from AliExpress in China
Have you noticed any improvements in any symptoms? How long may I ask have you used it for ?
About a year. It's just one of many things I do / supplements take/foods avoid etc. so really hard to say what is working . Especially as what is doing good may mean not deteriorating as fast as would do otherwise 😉But I'm a believer in 'marginal gains' rather than silver bullets. So if each thing we do makes us 1% better (on average), then doing 30 things hopefully makes me 30% better than otherwise.
That’s true about marginal gains adding up. Forget that sometimes. Do you have a picture of your hat by chance? Just curious what was used for the hat portion.
Plastic garden fencing! And lots of cable ties ebay.co.uk/itm/133884258232...
this is great thank you. I swear this picture looks familiar. I think I've seen it before. Does that device pulse the light? Is it a raspberry pi controller? I'm contemplating this led layout so it's great to see an example.
No, 1st time I've posted photos. Sorry, don't know technical details as a friend made it for me. I believe it is a raspberry pi case, but not sure what is inside. I will ask him.
Here are some more details of the components used - hope it helps someone who knows about electronics -I am not sure what all of it means! Everything my friend told me is below....
Logic controller: An ESP module espressif.com/en/products/m... (I used Wemos D1 Mini though any small ESP8266 or ESP32 module would work. These days I would use a module like this. unmannedtechshop.co.uk/prod...
A 12v buck (step-down) DC-DC converter module (the blue one) to power the LEDs from a 12-30V input. Not sure of the exact specs but it needs to be able to handle enough current for either the IR or Deep Red strips but not both together.
A 5v converter module (green) to provide power for the ESP8266 module (which has its own 3.3V regulator).
Enough 660nm Deep Red led strip to make about half of a hat
A similar amount of 810nm IR led strip (or a bit less as they use more cur)
2 x N-channel MOSFETs, one on the negative side of each LED strip, to perform the PWM switching.
4 (I think) 10K resistors associated with the FETs
A diode on the power input - to allow for higher power than when using USB for input.
A "Dallas" DS18B20 temperature sensor to measure the 12V module's temperature. This is probably not 100% required but protects it from overheating with extended use.
A stripboard base to mount and connect the modules
A box (raspberry pi case)
Silicone-insulated wires (for heat resistance)
The MOSFET circuits used drive the LED strips are something like shown here :circuitdigest.com/electroni.... Apparently I used IRF3708 but lots of similar ones would work as long as they will switch on fully with a gate voltage below 3.3V. I think there are 2 resistors for each MOSFET.
Each is driven by a GPIO pin on the ESP8266.
The firmware was built using ESPHome. esphome.io/
Of course it would be much neater to design a custom PCB onto which the modules and other components could be soldered. It's economical to get them made online if you want more than one or two.
This is some really great information. Thanks for posting it and thanks to your friend too. I appreciate it.
Just Google 670nm led strips and 810nm led strips. Plenty of sources come up: Like LEDLIGHTSWORLD ledlightsworld.com/products...
I had to buy mine in two different places to get the right nm.
670nm ledlightsworld.com/search?t...
810nm superlightingled.com/940nm8...
Make sure you choose the 810nm in the dropdown. Here is the video to make one although I'm using both wavelenghts and this video shows only one:

Hope this helps!
does it get hot wearing it? Do the leds produce a lot of heat?
Not really. Remember to only wear it for the recommended 12 minutes each wavelength for a total of 24 mins twice a day
Thank you. Have you noticed any improvement in any symptoms? How long have you used your led hat for?
I have just started using it this week. I'm not sure yet because it's only been a few days 
I hope it goes well I will try to remember to follow with you in a month. Do you happen have to have any pictures of your red light hat?
Bottom of hat.... Hope this helps Good luck to you too!
Thank you for the pictures. Seeing other people’s hat masterpieces is helping to keep me motivated and not discouraged, like the fact my finger dexterity is a lot worse than I thought after fiddling with wires and a tiny bits and pieces. Made me quite sad.
I am sorry to hear that. Maybe doing more things using your fingers would help improve your dexterity? Best of luck in creating your own masterpiece 😀
Why should you not wear it longer? I bought a handheld device called the cureray pro for my husband. It has both Nir and red light LEDs . I have used it for like half an hour on his forehead and brainstem. Is it a bad idea to overdo it? He has dementia and I am wondering if I am making it worse if I use the red light on him. His walking and movements are definitely improving. I really need to know more about this, and would appreciate more info. I bought Mark Sloans book on red light therapy, but did not get any guidelines on how much to use it.
I'm not sure if it's bad to overdo it but I believe there have been some negative effects for people. I just listed the time recommended by the company that makes the duo coronet.
Hi. I’m not familiar with the device you are using but longer isn’t always better. I wish I could be more helpful other than mentioning that. There is a channel on YouTube called brain-PBM. They have a variety of information on the use of photobiomodulation light therapy for things like Alzheimer’s dementia Parkinson’s TBI etc. hope it helps.
I've been using one similar to this one on Amazon for 2 years. It has both bands and a 40hz pulse: a.co/d/9lEMsgP
Hi This might be a helpful link. wellred.com.au/products
I want to thank everyone for their responses, I appreciate it. I will update this post as I make progress with the project.
I forgot to ask for those of you who made a homemade helmet or hat, how hot or warm does it get wearing it? Do the LEDs produce a lot of heat? I'm still trying to decide the type of helmet or hat to use to mount the LEDs to.
