- Does red light therapy work? Maybe, maybe not. What we do know for certain is that the people selling the led panels are marking up their prices 50x higher than what it should cost. See how you can buy the same LEDs from Aliexpress for a couple of dollars and strap it into a lamp from the dollar store and build your own DIY panel!
Unscripted Coding is entirely unscripted and organic. If you're looking for a tutorial, you're in the wrong place! What we do here is try and build something from scratch, filled with all the mistakes and lessons learned along the way!
Total Cost: $6
Total Time: 1 hour and 38 minutes

The idea would be to replicate a panel they're selling that's worth reproducing. 300 emitters total, dual 5W LED, 630/810 and 660/850, or 75 LEDs of each wavelength, you'll also need a housing, fans, DC adapter and lots of time and patience.
Yes. Or build something that is similar with 10 3-5w bulbs that you plug in. Not a red flash light.
Thank you for sharing. I love how simple this cost effective project was to create.
A parts list would perfect, in part, this excellent video. Thank you for producing it.
Apologies, but Aliexpress has a habit of delisting and relisting the LEDs, and the rest are just literally off the shelf components.
PARTS LIST??? Did you not watch the video??
This isn’t a red light panel. This is a silly experiment
This just popped up on UA-cam for me today, I don’t know why. Very cool and simple project. I don’t have a 3D printer so I appreciate how you recycled a dollar store case. thanks for the inspiration.
This was useful I think I’ll take this task on. A quick run down of components and pointers of where to begin if a layperson (me) wants to do this..would have been a bonus
Love this.... I'm going to start working on a panel
A benefit of the Dollar store light's design is that its standby current is zero. Duracell previously made some PWM flashlights that had a controller chip in the screw-on base. The standby current would almost always deplete the batteries, leading to leaking alkaline fuzz that ruined the flashlight.
On the other hand, the design of the Dollar store light is bad. Any mismatch in LED forward voltage drop will cause the one with the smaller drop to draw more current. At one time, best practices said that when diodes are put in parallel, a small resistor should be placed in series with each diode to improve current sharing. Unfortunately, for products like this one, keeping the bill of materials simple and the manufacturing cost low are the only two things that matter.
By the way, "100" most likely means 10 Ohms, not 100. The third digit is a multiplier. 100 would be written "101" (in other words, 10 E+01 Ohms).
The hero we all deserve
Hey there! I'm looking forward to more electronics oriented videos...fantastic work! not a lot of youtubers out there integrating electronics and coding!
Thanks! I always intend to do more, but there's just so many things I want to play around with!
@@UnscriptedCoding 🤣
This is a fun project. I was looking at one of those handheld LED device and it was a couple hundreds.
I love you so much thank you for making this
actually to date there are over 8000 studies that document LLLT efficacy. Red lite therapy is referring to the spectrum of red lite, usually LED's. However, cold lasers (not hot lasers) have been used in Russia for around 60 years to treat many many medical conditions, that we in the US have no effective treatment for particularly heavy duty infections. All of that aside, the devices are far too expensive for what they are made of. so more power to you for coming up with a way to make your own. If you can use low level red lasersand NIR lasers in addition to LED's you will have even more success. I can't wait to see what you come up with. (be careful of your eye with the lasers though)
Some of the devices are 1$ per led. The benefit is worth it.
@@fortezzasolutions It's a scam how much they are charging for it to be honest.
Gonna make one myself, it's literally just a LED device where the LED's are a few bucks per 100.
People can go ahead and spend 400 dollars on it if they like.
Do you have the link to the AliExpress store that you buy your lights (and do you know if they have the kind that reaches the brain?).
Thank you ✌️
Genius!❤
you have 3 battery so 4.5V. These leds need 2.2V to light up. So in theory you should need (8 leds x 2.2V )= 17.6 V. How it is possible?
Great job but I must say; Photomodulation therapy has been extensively scientifically proven to be effective.
Thanks! I don't want to comment on an area I don't know enough about. I encourage everyone to Google it quickly, there are definitely studies and research out there that you can read!
I came here looking for a diy red light therapy set up and you hit the mark perfectly for what i want to make. Do you have a parts list or links to the parts you bought? I need to find one of those cheap LED flash lights too.
Apologies, but Aliexpress has a habit of delisting and relisting the LEDs, and the rest are just literally off the shelf components.
Did you end up making your own red light therapy device?
No I bought a small flash light size one from Amazon for 20$
@@curtg7606 did it work like you wanted?
I'm curious, I've been looking through different options for doing something similar. I found grow panels for plants online. Have the same sort of setup as the red light panels but also at a fraction of the price. Would it be possible to just replace the lights in the grow panels for these red LED style? It has all the bells and whistles you would need for one of those panels except instead of it costing around $1,200 you could buy a panel for like a hundred bucks. Same size along with maybe $30 of lights.
In theory it should work. I wouldn't trust myself, I'm no expert at electronics. You want to know what sort of LEDs are on the existing panel and match them up. If they are different specs for example, you might supply too much power to your new red LEDs, and you'll need to put resistors in front them. Not to mention more expensive products usually have tailored housing. The cheap dollarama item was great, there was plenty of space to jam whatever I want in there. tl;dr I can't see why it wouldn't work conceptually, but I can see all sorts of complications showing up.
This is exactly my question ( nasa made this discovery in precisely this manner) how does one test that we are putting too much power through-as you suggest might be a problem? Thanks so much!
Did you check into the quality of lights you bought? Evidently there are huge differences and some may be less effective.
This isn't something I dug deep into. I was just curious about building it rather than whether it works or not, so all I can say is that's what it said from the seller and manufacturer, I have no reason to believe otherwise.
for the science , watch huberman lab episode "using light for health"
i liked it
can you provide the make and link to where to get the LEDS
If you just search aliexpress for "Deep Red 660nm LED" you'll find the same ones. Shops go up and down on aliexpress all the time unfortunately.
I thought the IR frequency between 860 and 940nm would be most beneficial for health purposes. Any idea on the 660nm then?
Honestly, I have no clue about any of the health stuff. IIRC, when I googled it quickly there were two ranges that were beneficial for different reasons. You and I are probably looking at different ranges.
Benefits start at 660
From my brief reading on the subject, the shorter wavelengths (amber/reddish-orange) are meant to penetrate less deeply into tissue, while the longer wavelengths (say, 860 or 940) offer deeper penetration. I am skeptical that bodily tissues have very narrowband responses to electromagnetic radiation; in other words, if you irradiate yourself with 880 nm (another wavelength available from inexpensive LEDs), the effects would likely be nearly identical to those obtained with 860 nm.
To some extent, I can appreciate the intent of having multiple wavelengths of LEDs in a panel; they are trying to emulate a broadband source, such as a blackbody radiator. However, there's a cynical side of me that says that slight differences in the designs of panels from Brand A vs. Brand B might exist simply for marketing purposes or to avoid patent infringement.
how did you put the pcbs together?
They fit nicely within the case, but if they didn't, I would have used some play-doh or modelling clay to fix them in place. No need for a lot of overthinking here.
is it better than tms for parkinsons plz?
Sorry, I'm not going to comment. Red light therapy hasn't been that well studied yet as far as I know.
Hello, can you please tell us how to make a red light device that can reach the brain?.
I have a brain injury and my brain is deteriorating fast, I don't have money to buy a device that can do that, so it would be of a huge help.
Thank you ✌️
Hello there,
Red light can’t penetrate the skull. What you need is 850nm infra red light which has been shown to penetrate the skull no problem and can benefit the brain, especially energy production in the brain, mitochondrial function, read up on it yourself.
You can buy IR lamps on Amazon called “IR illuminator” or “infrared illuminator”. They are used for security cameras but can be used for 20minutes at a time on your head put about 1 inch from your head. They cost around 30 to 50 dollars each. I would buy 5 of them and use them all at the same time.
You will need a 12volt power supply with a 2.1mm connector on the end to connect to the lamp. You can buy a one to many cable so that your power supply can supply multiple lamps at once. Buy a 5amp 12 volt supply to handle multiple lamps.
Ideally you would flash them at a frequency of between 1 to 4 hertz, ie. flashing anywhere from once to 4 times per second for optimum healing. There are 5 main frequency ranges for the brain. The lamps don’t need to be flashing to be of benefit though. I am currently working on getting my lamps to flash at set frequencies. Yes I will keep you informed if you put your email address in the comment reply if you reply, no problem. Best of luck
@@cdunne1620 Thank you so much for all the information.
I tried twice leaving my email, but I guess UA-cam deleted.
If you have a video of how to make them, please let me know. My brain is not functioning properly but I will give it a try.✌️
@@cdunne1620 Can you please tell me how to search for the article where you saw the wavelength need it to reach the brain?.
Thank you ✌️
@@luyzqint3760 luyz if you are there, make a video and on a piece of paper write your personal number and if can text you. Im gonna help you.
Would've been nice if you included link to LEDs to click and buy, avoid duplication of effort
Unfortunately I couldn't. Aliexpress links tend to rotate and die out. My original place of purchase no longer lists it, so you'll just have to search it up with the details given. Sorry for the hassle!
@@UnscriptedCoding ah bummer. Makes sense.
Thanks and check out Dr Hamblin. He explains the biphasic element which means you can overdose and reverse the healing. There are formulas but the intensity per square inch is needed to know how long to expose the light on a certain area before the reversal begins.
The led's are usually 5w or more each. Watts, and joules, wavelength are also important.
How long battery lasts ?
Sorry, I never measured it. I gifted this off, and I understand that it was fully useable, lasting many one-hour sessions on one set of AAA batteries. How many that is, no clue.
@@UnscriptedCoding Can I use these with wall socket ?
LEDs do not have a peak frequency output like a lazer - re-read the articles... nitty gritty in the details - make sure power output is enough to make medical light skin penatration ok...
I’m skeptical that aliexpress light are actually the nm they say they are. If that’s wrong, then it’s useless. 🤔
I've seen this idea spread elsewhere as well. I suspect the people who make the absurdly expensive panels are trying to keep their high margins. It doesn't cost manufacturers anything extra to tune to the right nm, there's no shortage of these LEDs. It is simply a less used color. If the manufacturer claims they are the right nm, I have no reason to believe or suspect otherwise.
power output significantly lower. the efficacy would be absolute trash, would have to spend so much time under the lights to compare to 5 mins on the high quality commercial brands. dont be fooled!
the power output is significantly different thats why the cost. Its not just about wavelength. The ones you purchased for cheap have terribly low power output so the efficacy is v low.
the big commercial panels have such greater power output that they have built in cooling systems like fans. dont be a moron.
I'm going to be honest here, red light therapy hasn't even been fully proven, and I think this "low power output" is just a new marketing ploy to get people to pay more for expensive brands. Regardless, we can rearrange how the batteries are wired to get much much higher power output to match. Wire them in series instead of parallel. The LEDs can handle the increased voltage (again they churn these out).
@@UnscriptedCoding im not sure what you mean by not proven…hundreds and hundreds of peer reviewed papers including rcts which is the highest standard of credibility does provide clinical evidence.
Again increasing power output generates substantial heat. Heat decreases efficacy. These commercial brands have huge cooling systems. I’m not sure why you think it’s all a rip off and a scam.
Not only soldering skills need improving, preparation of topic so you know how to do it, plus camera skills, no e case for not having subject in view... shame topic good content miserable
